It Seems Like Things Are Actually Cooling Down Between Israel and Iran

 It Seems Like Things Are Actually Cooling Down Between Israel and Iran

A rare bit of calming news from the Middle East: It seems that neither Israel nor Iran wants to widen the war.

The odds of a direct conflict between the region’s two most powerful countries seemed high for much of this month. On April 1, Israel attacked Iran’s consulate in Syria, killing seven senior officers of the Islamic Revolutionary Guard Corps. On April 13, Iran retaliated by launching a massive, multipronged attack—more than 300 missiles and drones, including 110 ballistic missiles—against Israel. Almost all the incoming weapons were shot down (a remarkable feat by U.S., Israeli, British, French, and Jordanian air defenses), no one was killed, and very little damage was sustained, and at just one air base. Still, the attack, which could have been deadly, marked the first time Iran had ever attacked Israeli territory. Israel felt the need to do something in response.

In the wee hours on Friday, three drones flew over an air base in the Isfahan district of southern Iran, not very far from a critical nuclear facility. Iran says they were all shot down. Maybe so, maybe not. The key facts are these: Israel has not acknowledged launching the drones—nor has Iran accused Israel of doing so. In fact, one senior Iranian official blamed the deed on “infiltrators” who fired the drones from inside Iran.

The point is, the widespread fears of mutual escalation—one airstrike sparking another, which sparks another, then another, on and on, for reasons of revenge, pride, a compulsion to “restore deterrence,” or whatever—have proved baseless, at least for now.

After the Saturday night air raid, an Iranian official warned Israel not to retaliate. Even a small Israeli attack, he said, would trigger a much more massive counterstrike from Tehran. President Biden urged Israeli Prime Minister Benjamin Netanyahu to heed the warning. Most Israelis felt they had to do something to deter future Iranian attacks. They wound up doing about as little as a powerfully armed country can do while still doing something—and Iran pretended that Israel didn’t launch the attack anyway, thus evading their pledge to respond to any such attack massively.


In sum, Iran proved that it can mount a massive attack on Israel, while Israel proved that its weapons have the range to strike targets inside Iran. That seemed to be enough for both sides. The equilibrium has thus been restored, at least for now.

As of midday Friday, the Israeli government seemed content to go along with the game, declining to comment on the drone strike. An exception was Itamar Ben-Gvir, the ultra-right-wing national security minister, who had pushed for a much more forceful response. “Lame!” he tweeted Friday morning in reference to the three-drone airstrike—thus acknowledging that Israel had launched the attack and that some senior officials wanted to do more. Netanyahu usually endorses Ben-Gvir’s radically hawkish statements, or at least doesn’t dispute them. But this time, Channel 12, Israel’s leading TV news station, reported that officials in the prime minister’s inner circle are very upset with the tweet, saying that it damaged Israel’s national security and slamming Ben-Gvir generally as “childish” and “irrelevant to any discussion.”

Meanwhile, the aftereffects of Iran’s attack last weekend continue to benefit Israel. On Wednesday, 48 countries signed a statement condemning Iran for its attack on Israel. The palpable sign of Israel’s continued vulnerability is also likely to boost approval of President Biden’s emergency military-aid package, which the House will take up on Saturday. Before the attack, many of those countries would have been reluctant to endorse any expression of support for Israel—and Biden’s aid package was losing support—as a result of Israel’s “over-the-top” military tactics (as even Biden called them) in Gaza.


The prospect of a major war between Iran and Israel distracted the world’s focus from the fighting and suffering in Gaza, but probably not for long. U.S. and Israeli officials remain locked in disagreement over how to rout the last battalion of Hamas terrorists from the town of Rafah on Gaza’s southern tip, where more than 1 million civilians—most of them refugees from the northern towns—are crowded, many of them starving. Netanyahu and the other members of his war Cabinet want to mount a major offensive against Rafah. Biden and his aides urge them not to take that step unless they come up with a way to avoid killing tens of thousands of the civilians. The Israelis have not come up with any such way. Nor have the Americans thought up a way to rout Hamas’ last battalion without an armed offensive.

This is why U.S., Egyptian, and Qatari diplomats continue to hammer out a plan for a cease-fire, combined with an exchange of Israeli hostages held by Hamas for Palestinian prisoners held by Israel. Hamas has rejected several proposals, most of them endorsed by Israel. Its one counteroffer—a cease-fire that delays the release of any hostages until all Israeli troops have withdrawn from Gaza—is unacceptable to Israel.

Bitcoin just completed its fourth-ever 'halving,' here’s what investors need to watch now

 Bitcoin just completed its fourth-ever 'halving,' here’s what investors need to watch now




The Bitcoin network on Friday night slashed the incentives rewarded to miners in half for the fourth time in its history.

The celebrated event, which takes place about once every four years as mandated in the Bitcoin code, is designed to slow the issuance of bitcoins, thereby creating a scarcity effect and allowing the cryptocurrency to maintain its digital gold-like quality.

There may be some speculative trading on the event itself. JPMorgan said it expects to see some downside in bitcoin post-halving and Deutsche Bank said it "does not expect prices to increase significantly." However, the impact may be bigger months from now, even if bitcoin continues its trend of diminishing returns from its halving day to its cycle top. Two key things to watch will be the block reward and the hash rate.


"While the upcoming Bitcoin halving will create a supply shock as the previous ones had, we believe its impact on the cryptocurrency's price could be magnified by the concurrent demand shock created by the emergence of spot bitcoin ETFs," said Benchmark's Mark Palmer.

The bigger immediate impact will be to the miners themselves, he added. They're the ones that run the machines that do the work of recording new blocks of bitcoin transactions and adding them to the global ledger, also known as the blockchain.

"Miners with access to inexpensive, reliable power sources are well positioned to navigate the post-halving market dynamics," said Maxim's Matthew Galinko in a note Friday. "Some miners, many that are not public, could exit the market with a combination of poor access to power, efficient machines, and capital. Miners with capital and relatively expensive power will likely find opportunities in the wake of potential consolidation and disruption driven by the halving."

The block reward

Miners have two incentives to mine: transaction fees that are paid voluntarily by senders (for faster settlement) and mining rewards — 3.125 newly created bitcoins, or about $200,000 as of Friday evening, when the mining reward shrunk from 6.25 bitcoins. The incentive was initially 50 bitcoins.

The reduction in the block rewards leads to a reduction in the supply of bitcoin by slowing the pace at which new coins are created, helping maintain the idea of bitcoin as digital gold — whose finite supply helps determine its value. Eventually, the number of bitcoins in circulation will cap at 21 million, per the Bitcoin code. There are about 19.6 million in circulation today.

"Miners utilize powerful, specialized computer hardware to validate transactions on the Bitcoin network and record them permanently on the blockchain," Deutsche Bank analyst Marion Laboure said. "This process, known as mining, rewards miners with newly minted bitcoins. But with each halving, the reward to mining is decreased to maintain scarcity and control the cryptocurrency's inflation rate over time."

The hash rate

Historically after a halving, the Bitcoin hash rate – or the total computational power used by miners to process transactions on the Bitcoin network – has fallen, pricing some miners out of the market. It generally recovers in the medium term, however, Laboure pointed out.

The network hash rate has been hitting all-time highs for months as miners tried to take market share ahead of the halving. Growth in the Bitcoin hash rate dilutes individual miners' contribution to the network hash rate.

"In the past three halvings, the network recovered its pre-halving hash rate levels within an average of 57 days," she said. "It is also likely that the current elevated prices of bitcoin may limit this short-term dip in the hash rate, as bitcoin miners enjoy record high profits in the lead-up to the halving."

Palmer said the impact of the halving on bitcoin miners' economics could be "more than offset over time" if bitcoin's price rallies keep pushing the cryptocurrency to new highs in the months ahead.

U.S. Mortgage Rates Jump Above 7% for the First Time This Year

 U.S. Mortgage Rates Jump Above 7% for the First Time This Year


Rates on 30-year mortgages — the most common kind among U.S. homeowners — surpassed the 7 percent mark on Thursday, a troublesome sign for an already tight housing market.



Mortgage rates rose above 7 percent for the first time this year, crossing a symbolically concerning threshold that threatens to keep millions of potential home buyers and sellers on the sidelines of a U.S. housing market that is increasingly showing signs of slowing.

The average rate on 30-year mortgages, the most popular home loan in the United States, rose to 7.1 percent this week, Freddie Mac reported on Thursday, the highest since November. Mortgage rates reached a recent high of nearly 8 percent late last year — a level not seen since 2000.

As mortgage rates have risen in recent months, making homeownership costlier for buyers, potential sellers who may feel locked into lower rates on their existing loans have been keeping their houses off the market, in effect pushing prices higher, too. Combined, the forces have fed into a broader feeling of frustration about the economy, at a time when inflation has remained hotter than expected.

“Potential home buyers are deciding whether to buy before rates rise even more, or hold off in hopes of decreases later in the year,” Sam Khater, Freddie Mac’s chief economist, said in a statement. “It remains unclear how many home buyers can withstand increasing rates in the future.”

At the same time, the market has slowed. Sales of existing homes fell by 4.3 percent in March and 3.7 percent from a year earlier, according to the National Association of Realtors.

In April 2021, mortgage rates were at about 3 percent, less than half the current rate. They began to climb that year and continued to rise in 2022 when the Federal Reserve started raising its benchmark rate in an effort to combat inflation. Although inflation has since cooled significantly, it’s still above the central bank’s 2 percent target.

The Fed has signaled in recent months that it may keep the cost of borrowing higher for longer amid stubborn inflation. The Fed’s benchmark interest rate is currently the highest it’s been in 22 years.

Mortgage lenders generally watch the 10-year Treasury bond, which is tied to mortgage rates, and expectations that the Fed will keep rates high has pushed up Treasury yields. The 10-year Treasury yield has soared since the start of the year, now sitting at about 4.6 percent.

The N.A.R. agreed to settle litigation last month that would eliminate the standard sales commission, a move housing experts say could bring down home prices. Sellers currently pay a 5 or 6 percent commission to a real estate agent, a cost that’s typically passed onto the buyer through a higher sticker price.

Britain is set to impose tough measures to stub out smoking, which has emerged as one of the biggest causes of cancer deaths in the country.

Parliament approved the government’s “historic” plans to create a “smoke-free” generation on Tuesday in a bid to reduce the number of people dying from smoking-related diseases, a big burden on the country’s publicly funded National Health Service (NHS).

Dubai flooding hobbles major airport's operations as "historic weather event" brings torrential rains to UAE

 Dubai flooding hobbles major airport's operations as "historic weather event" brings torrential rains to UAE





Dubai, United Arab Emirates — The desert nation of the United Arab Emirates attempted to dry out Wednesday from the heaviest rain ever recorded there after a deluge flooded out Dubai International Airport, disrupting travel through the world's busiest airfield for international travel. The state-run WAM news agency called the rain Tuesday "a historic weather event" that surpassed "anything documented since the start of data collection in 1949." 

The rains began late Monday, soaking the sands and roadways of Dubai with some 0.79 inches of rain, according to meteorological data collected at Dubai International Airport. The storms intensified around 9 a.m. local time Tuesday and continued throughout the day, dumping more rain and hail onto the overwhelmed city.


Flooding impacts Dubai International Airport

By the end of Tuesday, more than 5.59 inches of rainfall had soaked Dubai over 24 hours. An average year sees just 3.73 inches of rain fall at Dubai International Airport, a hub for the long-haul carrier Emirates.

At the airport, standing water lapped on taxiways as aircraft landed. Arrivals were halted Tuesday night and passengers struggled to reach terminals through the floodwater covering surrounding roads.

TOPSHOT-UAE-BAHRAIN-OMAN-WEATHER-FLOOD

The airport said in a series of social media posts that all operations were halted for about 25 minutes on Tuesday afternoon and that all arrivals would be diverted after that "until the weather conditions improve." Late Wednesday morning, the airport and the flagship carrier Emirates were still warning travelers not to come to the airport unless absolutely necessary, saying all flight check-in was still suspended.

"Flights continue to be delayed and diverted. Please check your flight status directly with your airline," the airport said in a tweet. "We are working hard to recover operations as quickly as possible in very challenging conditions." 


One couple, who spoke to The Associated Press on condition of anonymity in a country with strict laws that criminalize critical speech, called the situation at the airport "absolute carnage."

"You cannot get a taxi. There's people sleeping in the Metro station. There's people sleeping in the airport," the man said Wednesday.

They ended up getting a taxi to near their home some 18 miles away, but floodwater on the road stopped them. A bystander helped them over a highway barrier with their carry-on luggage, the bottles of gin they picked up from a duty-free store clinking away.

Passengers wait at a flight connection desk at Dubai International Airport, April 17, 2024, amid flight delays and cancelations caused by flash flooding brought by a historic rain storm.


Paul Griffiths, the airport's CEO, acknowledged continued issues with flooding Wednesday morning, saying every place an aircraft could be safely parked was taken. Some aircraft had been diverted to Al Maktoum International Airport at Dubai World Central, the city-state's second airfield.

"It remains an incredibly challenging time. In living memory, I don't think anyone has ever seen conditions like it," Griffiths told the state-owned talk radio station Dubai Eye. "We are in uncharted territory, but I can assure everyone we are working as hard as we possibly can to make sure our customers and staff are looked after."


Did "cloud-seeding" contribute?

Rain also fell in Bahrain, Oman, Qatar and Saudi Arabia. However, the rains were acute across the UAE. One reason may have been "cloud seeding," in which small planes flown by the government go through clouds burning special salt flares. Those flares can increase precipitation.

Several reports quoted meteorologists at the National Center for Meteorology as saying they flew six or seven cloud-seeding flights before the rains. The center did not immediately respond to questions Wednesday, though flight-tracking data analyzed by the AP showed one aircraft affiliated with the UAE's cloud-seeding efforts flew around the country Sunday.

The UAE, which relies heavily on energy-hungry desalination plants to provide water, conducts cloud seeding in part to increase its dwindling, limited groundwater.


Flooding closes schools across UAE

Schools across the UAE, a federation of seven sheikhdoms, largely shut ahead of the storm and government employees were largely working remotely if they could. Many workers stayed home as well, though some ventured out, with the unfortunate ones stalling out their vehicles in deeper-than-expected water covering some roads.

Cars are seen on a flooded street during a rainstorm in Dubai, United Arab Emirates, April 16, 2024.

Authorities sent tanker trucks out into the streets and highways to pump away the water. Water poured into some homes, forcing people to bail out their houses.

The country's hereditary rulers offered no overall damage or injury information for the nation, as some people slept in their flooded vehicles Tuesday night. In Ras al-Khaimah, the country's northernmost emirate, police said a 70-year-old man died when his vehicle was swept away by floodwater.

Fujairah, an emirate on the UAE's eastern coast, saw the heaviest rainfall Tuesday with 5.7 inches falling there.

Authorities canceled school and the government instituted remote work again for Wednesday.

Rain is unusual in the UAE, an arid, Arabian Peninsula nation, but occurs periodically during the cooler winter months. Many roads and other areas lack drainage given the lack of regular rainfall, causing flooding.

Meanwhile in neighboring Oman, a sultanate that rests on the eastern edge of the Arabian Peninsula, at least 19 people were killed in heavy rains in recent days, according to a statement Wednesday from the country's National Committee for Emergency Management. That includes some 10 schoolchildren swept away in a vehicle with an adult, prompting condolences from rulers across the region.

U.S. to hit Iran with fresh sanctions after Israel attack

 

U.S. to hit Iran with fresh sanctions after Israel attack

The U.S. will impose new sanctions on Iran's missile and drone program after the country's unprecedented attack on Israel over the weekend, White House national security adviser Jake Sullivan announced Tuesday evening.

Why it matters: President Biden is urging Israeli Prime Minister Benjamin Netanyahu to exercise military restraint. But in the economic sphere, the administration is demonstrating a willingness to retaliate against Iran.

🔸These new sanctions and other ones Treasury Secretary Janet Yellen is preparing represent a subtle message to Israel that there is more than one way to harm the ruling regime in Tehran.

Driving the news: Sullivan said in a statement that Biden is working in coordination with international partners including G7 nations and bipartisan leaders in Congress on a comprehensive response to Iran's attack.

🔸U.S. defense agencies are working on strengthening air and missile defense and early warning systems across the Middle East.
🔸The new sanctions will also target entities supporting the Islamic Revolutionary Guard Corps (IRGC) and Iran's Defense Ministry. "We anticipate that our allies and partners will soon be following with their own sanctions," Sullivan said.
🔸Meanwhile, Yellen vowed that the U.S. "will not hesitate" to inflict economic punishment in response to Iran's attack.
What's next: Yellen will press fellow finance ministers — visiting D.C. for the annual spring IMF meetings this week — to focus their governments on possible sanctions work with the U.S. on coordinated actions.

🔸"Treasury will not hesitate to work with our allies to use our sanctions authority to continue disrupting the Iranian regime's malign and destabilizing activity," Yellen is prepared to say Tuesday during her opening remarks at a press conference.


🔸"The attack by Iran and its proxies underscores the importance of Treasury's work to use our economic tools to counter Iran's malign activity," she will say, according to a copy of her remarks obtained by Axios.

🔸The G7 is also considering sanctions with the goal of isolating Iran internationally and increasing economic pressure on the regime, White House national security spokesman John Kirby told reporters Monday.


🔸"We now have a unified alliance of partners," he said. "That wasn't Iran's intent."



Flashback: Days after Hamas Oct. 7 attack on Israel, the Biden administration announced new sanctions against Hamas leaders and financial facilitators.

Zoom out: Republicans have criticized the Biden administration for not doing more to check the aggression of Iran and Iranian-backed forces throughout the Middle East.

🔸Biden's warning to Netanyahu to temper any possible Israeli counterattack against Iran was hit with a barrage of criticism Sunday, including from some Democrats.

🔸Last September, Republicans pilloried the president for releasing some $6 billion in Iranian oil revenue as part of a hostage swap deal.

🔸In January, after a pro-Iranian militia killed three U.S. service members in Jordan, some GOP lawmakers called for attacks on targets inside of Iran.

🔸Instead, Biden ordered strikes against Iranian groups in Iraq and Syria.

Zoom in: House Republicans have scheduled more than a dozen votes for this week on bills sanctioning Iran and its proxies in retaliation for last weekend's wide-ranging drone and missile attack on Israel.

Go deeper: Blinken: Escalation with Iran is not in U.S. or Israel's interests

Editor's note: This article has been updated with details of the White House national security adviser's announcement.

Updated 9 hours ago - World Blinken: Escalation with Iran is not in U.S. or Israel's interests

 

Blinken: Escalation with Iran is not in U.S. or Israel's interests







Secretary of State Antony Blinken told a group of American Jewish leaders on Tuesday that further escalation with Iran is not in the interests of either the U.S. or Israel, three people who attended the meeting told Axios.

Why it matters: The Biden administration and several other Western countries allied with Israel are urging Benjamin Netanyahu's government not to rush into a retaliation against Iran that could lead to a regional war.


🔸The U.S. assessment is that Iran would respond to any significant, overt Israeli strike     on Iranian soil with a new round of missile and drone attacks, a senior U.S. official told     Axios.

🔸"We think it will be very hard to replicate the huge success we had on Saturday with defeating the attack if Iran launches hundreds of missiles and drones again — and the Israelis know it," another U.S. official said.

Behind the scenes: A person who attended the meeting said Blinken did not say that Israel should refrain from responding to Iran, stressing it was Israel's decision to make.

🔸"But his message was: be smart, strategic and limited as possible," the attendee said.

🔸"Strength and wisdom are two sides of the same coin," Blinken told the Jewish leaders.

🔸Blinken said that "we would never tell Israel what to do," and that the Biden administration was simply giving Israel the best advice it can, according to two people who attended the meeting.


The intrigue: Blinken told the group that the fact that Jordan and Saudi Arabia were part of the defensive effort to repel Iran's attack was very important and opens opportunities for the future, according to one attendee.

🔸Blinken also claimed that Hamas may have rejected the most recent hostage deal because it thought the Iranian attack might lead to a regional conflict, two attendees said.


🔸He added that if Hamas sees there is no regional war, the militant group will once again be under pressure to cut a hostage deal.


🔸The State Department declined to comment.


Zoom in: Blinken spoke on Monday with Benny Gantz, a minister in Israel's war cabinet, and conveyed a similar message regarding Israel's possible retaliation, two sources with knowledge of the call said.

🔸Gantz said on Tuesday that he's spoken to senior U.S. officials over the last 24 hours about the need for the international community to take action against Iran, including imposing more sanctions in order to stop its aggression.


🔸"Israel will work with its allies around the world to make it happen. A regional normalization process will serve this goal. Israel will act with strategic wisdom and respond in the time and place of its choosing," Gantz said at a policy conference.


🔸The call between Blinken and Gantz, which hasn't been disclosed publicly, is one of a series of calls between senior U.S. and Israeli officials in recent days focused on Israel's plans for retaliation.

🔸Secretary of Defense Lloyd Austin spoke on Monday with his Israeli counterpart Yoav Gallant. It was their fourth call since the Iranian attack on Saturday.


The other side: Iranian President Ebrahim Raisi told Russian President Vladimir Putin in a phone call Tuesday that Iran doesn't seek further escalation, according to Iranian state news agency IRNA.

🔸"We will respond to any action against Iran's interests more fiercely, extensively and painfully than before," Raisi stressed, according to IRNA.

🔸The Kremlin said Putin "expressed hope that all sides would show reasonable restraint and prevent a new round of confrontation fraught with catastrophic consequences for the entire region."

SM-3 Ballistic Missile Interceptor Used for First Time in Combat, Officials Confirm

 SM-3 Ballistic Missile Interceptor Used for First Time in Combat, Officials Confirm


On Nov. 16, U.S. Missile Defense Agency and Navy sailors aboard USS John Finn (DDG 113), an Aegis Ballistic Missile Defense System-equipped destroyer, fired a Standard Missile-3 (SM-3) Block IIA guided missile that successfully intercepted and destroyed a mock Intercontinental Ballistic Missile (ICBM) during a flight test demonstration in the broad ocean area northeast of Hawaii in November 2020. MDA photo.


For the first time in combat, guided-missile destroyers fired missiles developed to intercept ballistic missiles during the U.S. response to the Iranian attack on Israel, USNI News has learned.

USS Arleigh Burke (DDG-51) and USS Carney (DDG-64), in the Eastern Mediterranean, fired four to seven Standard Missile 3s to intercept Iranian ballistic missiles headed toward Israeli targets over the weekend, two defense officials confirmed to USNI News on Monday.

Carney and Arleigh Burke have versions of the Aegis combat system that were modified to track and target ballistic missiles. The SPY-1D radar on the destroyers cues the SM-3 to attack the ballistic missile. The SM-3 transports a kill vehicle outside the atmosphere to intercept a ballistic missile near the height of its path from its launch point before it reenters the atmosphere to hit its target.

Both the destroyers were placed off the coast of Israel as part of the defensive measures against a Iranian strike in retaliation for an Israeli attack on an Iranian embassy in Syria.

It’s unclear what missiles the Iranians fired toward Israel, but, according to missile analyst Chris Carlson, the fact the Navy used SM-3s points to the likelihood the Iranians used some of its medium-range ballistic missiles with a range of up to 1,800 miles.

First deployed in early 2004 on U.S. cruisers and destroyers, the SM-3s have been part of the U.S. ballistic missile defense network across the world. In 2011, the U.S. announced it would deploy four U.S. BMD destroyers in Rota as part of the European Phased Adaptive Approach to BMD along with missile defense sites based on the Aegis technology in Poland and Romania that also use SM-3s. The EPAA was specifically created during the Obama administration to protect Europe from Iranian ballistic missiles.

Burke is currently part of the U.S. destroyer contingent in Rota, and Carney had previously been stationed there as part of the mission. Likewise, BMD destroyers and cruisers patrol near Japan and South Korea as a hedge against potential North Korean ballistic missile attacks.

While variants of the missile have been in use for more than two decades and have undergone a wide range of tests, they have never been used in a real-world situation.

“Until you use it in combat, there are always questions,” Carlson told USNI News .
 

Trump Media Stock Plunges, Extending Recent Losses

 Trump Media Stock Plunges, Extending Recent Losses


Funds that bet on a fall were set to profit as the parent of Truth Social came under renewed pressure after it registered new shares for a potential sale.

Shares of former President Donald J. Trump’s social media company plunged on Monday after the company filed to register the potential sale of tens of millions of additional shares.

Trump Media & Technology’s stock fell 18.3 percent, erasing hundreds of millions of dollars from the company’s market value — and putting a dent in Mr. Trump’s majority stake. Since a surge in its first days of trading as Trump Media, which lifted the value of the company to about $8 billion at one point last month, the company’s shares have dropped by around 60 percent.

Trump Media was expected to register the potential sale of new shares after the completion of its merger last month with Digital World Acquisition Corp., a cash-rich shell company known as a SPAC. Companies that merge with SPACs, or special purpose acquisition companies, typically file a registration statement a few weeks after the deal is completed for the sale of additional securities held by early investors.

70 million Americans under severe weather threat from Northeast to Midwest

 70 million Americans under severe weather threat from Northeast to Midwest

From Sunday through Tuesday, hail, winds and a few tornados are possible.

Severe weather is projected to impact 70 million Americans from the Northeast Sunday through to Tuesday in the Midwest.

NOAA's Storm Prediction Center has issued an enhanced risk outlook for the multi-region storm system, designating it a level 3 out of 5 risk for severe weather.

In the Northeast, intense thunderstorms are likely to develop late Sunday afternoon in a corridor across the upper Ohio Valley into the Pocono Mountains in Pennsylvania and the Catskill region in Upstate New York.

Damaging wind, some hail and tornadoes are possible as the storm spreads slowly southward into Sunday evening.
ABC NewsSevere risk forecast for Sunday evening.

A line of these strong to potentially severe storms is projected to impact cities from Pittsburgh to New York Sunday night from 10:00 p.m. ET to 11:00 p.m. ET.

In the Midwest, a dynamic weather system across the Rockies and into the Great Plains from the Dakotas to Texas has the potential to form storms capable of becoming supercells and produce very large hail, damaging winds, and tornadoes on Monday.

ABC NewsSevere weather outbreak forecast for Monday and Tuesday.

Scattered severe thunderstorms are likely across the southern to central Great Plains, mainly Monday evening when large hail, damaging wind and a few tornadoes are possible.

Storms may begin as early as 5:00 p.m. CT from Central Texas to Nebraska and then continue to develop overnight across the region.

By Tuesday morning, storms are projected to impact regions from eastern Nebraska to Kansas City, Missouri, and parts of Iowa. These storms may still be strong and possibly severe.
The strongest storms are anticipated in areas from Des Moines, Iowa, to Columbia, Missouri, on Tuesday afternoon.

Scattered severe thunderstorms are likely on Tuesday into the evening from Chicago to east of Dallas.

On Wednesday morning, there may be lingering strong to severe storms in the Ohio River Valley.

NASA unveils probe bound for Jupiter's possibly life-sustaining moon

 NASA unveils probe bound for Jupiter's possibly life-sustaining moon


NASA's Europa Clipper Spacecraft is headed for one of Jupiter's moons to see if it has the right conditions to sustain life.
US space scientists on Thursday unveiled the interplanetary probe NASA plans to send to one of Jupiter's icy moons as part of humanity's hunt for extra-terrestrial life.

The Clipper spacecraft is due to blast off in October bound for Europa, one of dozens of moons orbiting the solar system's biggest planet, and the nearest spot in our celestial neighborhood that could offer a perch for life.

"One of the fundamental questions that NASA wants to understand is, are we alone in the cosmos?" Bob Pappalardo, the mission's project scientist told AFP.

"If we were to find the conditions for life, and then someday actually find life in a place like Europa, then that would say in our own solar system there are two examples of life: Earth and Europa.

"That would be huge for understanding how common life might be throughout the universe."

The $5 billion probe is currently at NASA's Jet Propulsion Laboratory in California, sitting in a "clean room"—a sealed area only accessible to people wearing head-to-toe covering.

The precautions are to ensure the probe remains free of contaminants to avoid transporting Earthly microbes to Europa.

After transport to Kennedy Space Center in Florida, Clipper is set to launch aboard a Space X Falcon Heavy rocket and begin an over-five-year journey that involves a pass by Mars to pick up speed.

In 2031, it should be in orbit around Jupiter and Europa, where it will begin a detailed study of the moon scientists believe is covered in frozen water.

"We have instruments like cameras, and spectrometers, a magnetometer and a radar that can... penetrate right through ice, bounce off liquid water and back to the surface to tell us how thick is the ice and where is liquid water located," Pappalardo said.

Mission managers do not expect to find little green men swimming in the water—in fact, they're not even looking for life itself, only for the conditions that could support it.

Scientists know from extreme environments on Earth—like light-starved geothermal vents located deep under the polar ice cap—that tiny beings can find purchase almost anywhere.

And conditions on Europa, which is almost as large as Earth's moon, could provide a similar habitat, offering the tantalizing prospect we are not alone—not even in our own solar system.

"If moons around planets far away from stars could hold life, then the number of opportunities around the solar system, around the universe, where life could take hold, I think goes up dramatically," said Jordan Evans, project manager for the Europa Clipper mission.

Challenges

The science is not easy—a powerful radiation field around Europa could degrade the instruments, which will be getting the equivalent of 100,000 chest X-rays every circuit around the moon.

The vast distances involved mean that when Clipper sends its data back, the signal will take 45 minutes to arrive at Mission Control.

And despite its massive solar array, which unfurls once in space, keeping Clipper powered will be a major challenge, Evans said.

"Right after launch, (the solar panels are) putting out 23,000 watts... but when we're out at Jupiter, so far away from the sun, they're only putting out 700 watts," he said.

"Near Earth, they could power 20 houses continuously. And when we're at Jupiter, just a few light bulbs and some small appliances."

The mission, planning for which began in the late 1990s, is expected to conclude around 2034, when Clipper will likely have reached the end of its useful life.

The probe will then have one final port of call: Jupiter's largest moon, deputy project manager Tim Larson said.

"After we're done with the science mission, the way we end is by crashing into one of the other bodies in the Jovian system to dispose of the spacecraft," he said.

"Right now, the plan is to go into Ganymede."

Two 100-foot asteroids set to pass Earth today; NASA reveals how close these scary space rocks will come

 

Two 100-foot asteroids set to pass Earth today; NASA reveals how close these scary space rocks will come


NASA tracks as many as 4 approaching asteroids, including two 100-foot space rocks. These two asteroids will approach Earth today.

The US space agency, the National Aeronautics and Space Administration, better known through its abbreviation NASA, has revealed that as many as four asteroids are silently making their way towards Earth. Each one varies in size. While asteroids are definitely something to be scared of as they have impacted Earth on many occasions in its long history leading to global scale destruction, none of these have any chance of impacting our planet. The reason behind it is that NASA’s scientists are constantly tracking their movements and this has revealed they will get very close to Earth, but they pose no danger. Their close encounter with Earth is imminent though and as many as two asteroids are 100-foot monsters and they will approach today.

The first is Asteroid 2024 FR3. It is approximately the size of an airplane. This is a 78-foot asteroid and despite its large size, it is set to maintain a safe distance of 824,000 miles from Earth.

The second is the plane-sized Asteroid 2024 FG3. This is a 100-foot asteroid and it will pass Earth at a safe distance of 1,940,000 miles.

The third is Asteroid 2024 FN3 and it too will pass Earth today. This is also a 100-foot asteroid that is well on its way to Earth in its long journey. This asteroid will get as close as 4,220,000 miles to Earth.

The fourth is Asteroid 2024 FL3. It too is a 100-foot monster in size, but it will make its closest approach on April 3, 2024. Traveling at a distance of 2,030,000 miles from Earth, it marks the end of this series of encounters.

The important thing to note here is that the Universe is huge and many of these space rocks, which tumble out of the asteroid belt due to some reason or the other, get extremely close to Earth. NASA and other global space agencies track these asteroids to ensure that none of them are heading for a potential calamitous crash against the Earth.

While none of these asteroids posed an immediate threat, their close brushes are a scary reminder of the dangers ever-present in space that have to be closely monitored because of the potential dangers.

Mars exploration: NASA's Curiosity searches for new clues about ancient water

 Mars exploration: NASA's Curiosity searches for new clues about ancient water


A recent study by an international team has suggested that Mars might have retained more water for a longer period than previously thought.


The presence of water on Mars—Earth’s neighbour —is not an alien concept. Astronomers over decades have talked about the presence of water on the Red Planet without evidence. However, a recent study by an international team has suggested that the fourth planet of the solar system from the Sun might have retained more water for a longer period than previously thought.

As the Curiosity rover of the National Aeronautics and Space Administration (NASA) has begun exploring a new region of Mars i.e Gediz Vallis channel—appears to have been carved by an ancient river—it could reveal more about when liquid water disappeared once and for all from the Red Planet’s surface.

The rover team is focusing on the Gediz Vallis channel and searching on for evidence that would confirm how the channel was carved into the underlying bedrock. The formation’s sides are steep enough that the team doesn’t think the channel was made by wind.

The rover’s journey through this region aims to find out the process of the Gediz Vallis channel formation—whether the debris flows (rapid, wet landslides) or a river carrying rocks and sediment could have formed the bedrock. Scientists are also eager to find out whether the debris was transported by water or dry avalanches.

Since 2014, Curiosity has been ascending the foothills of Mount Sharp above the floor of Gale Crater to explore the evaluation of the Mars climate change. The study of layers in the lower part of Mount Sharp formed over millions of years may provide scientists a clue as to how the presence of both water and the chemical ingredients required for life changed over time. These layers present a chronological record of Mars’ environmental changes, crucial for understanding its potential for past life.

“If the channel or the debris pile were formed by liquid water, that’s really interesting. It would mean that fairly late in the story of Mount Sharp – after a long dry period – water came back, and in a big way," said Curiosity’s project scientist, Ashwin Vasavada of NASA’s Jet Propulsion Laboratory in Southern California.


Last year, Curiosity made a challenging ascent to study the ridge, which drapes across the slopes of Mount Sharp and seems to grow out of the end of the channel, suggesting both are part of one geologic system.

This Curiosity exploration contributes to a growing body of evidence suggesting Mars experienced water in phases, with periods of aridity interspersed with significant watery intervals. Discoveries like mud cracks, remnants of shallow lakes, and evidence of the complexity of Mars's hydrological past, Massive debris flows underscore the complexity of Mars’ hydrological past.

Pluto declared ‘official state planet’ of this US state

Arizona—a southwestern US state—has recently declared Pluto as its ‘official state planet’ despite the ‘dwarf planet’ being stripped of its official status as a planet in 2006 by the International Astronomical Union
This Pluto image was taken in July 2015, when NASA's New Horizons spacecraft was 476,000 miles (768,000 kilometers) from the surface
Arizona--a southwestern US state—has recently declared Pluto as its ‘official state planet’ despite the ‘dwarf planet’ being stripped of its official status as a planet in 2006 by the International Astronomical Union

Last Friday (i.e. March 29), Arizona governor Katie Hobbs signed a legislation declaring the ‘dwarf planet’ as the ‘official state planet’ of the US state, reported The Arizona Daily Star. When quizzed on whether the Pluto is a full-fledged planet? The Arizona governor dodged the question saying “I am proud of Arizona’s pioneering work in space discovery."

It is important to note that Pluto was discovered by American astronomer Clyde Tombaugh at the Lowell Observatory in Flagstaff of Arizona in 1930. Pluto happens to be the only planet to be discovered in the US.

“The whole story of Clyde is just amazing, just sitting there under the telescope’’ looking for planets by taking photos over a period of time," said Arizona state Republican Justin Wilmeth (R-Phoenix), who praised the Pluto legislation.

Senator Sally Ann Gonzales (D-Tucson)--one among the five senators who voted against the legislation--said, “Scientifically, they took it out of being a planet." Gonzales added that lawmakers must take scientific information into account, “something that we as a Legislature, as a body, sometimes omit.’’

What is the status of Pluto?
In 2006, the International Astronomical Union (IAU) voted to remove Pluto from the group of planets, claiming that the icy object at the edge of the solar system failed to meet the full and proper definition of planets. The IAU reclassified Pluto as a “dwarf planet."

According to NASA, “Pluto is a dwarf planet located in a distant region of our solar system beyond Neptune known as the Kuiper Belt. It was long considered our ninth planet, but the International Astronomical Union reclassified Pluto as a dwarf planet in 2006."

“It was named by 11-year-old Venetia Burney of Oxford, England," the US space agency added.

Pluto is classified as a dwarf planet because, “while it is large enough to have become spherical, it is not big enough to exert its orbital dominance and clear the neighbourhood surrounding its orbit," ass per Encyclopedia Britannica.

The website noted that Pluto’s “demolition" felt like a “break from tradition" to many across the globe. It added that the step was, however, “a positive step forward into a new light, new knowledge, and changing perspectives of the universe."

NASA further said, “When Pluto was reclassified in 2006 from a planet to a dwarf planet, there was widespread outrage on behalf of the demoted planet. As the textbooks were updated, the internet spawned memes with Pluto going through a range of emotions, from anger to loneliness. But since the release of New Horizons images showing a very prominent heart-shaped feature on the surface, the sad Pluto meme has given way to a very content, loving Pluto that would like to once again be visited by a spacecraft."

“The Disney cartoon character Pluto, Mickey's faithful dog, made his debut in 1930, the same year Clyde Tombaugh, an astronomer at the Lowell Observatory in Flagstaff, Arizona, discovered the dwarf planet. There is speculation that Walt Disney named the animated dog after the recently discovered planet to capitalize on its popularity, but other accounts are less certain of a direct link," the US space agency added.

Milky Way’s Earliest Building Blocks Found, Named Shiva & Shakti

 

Milky Way’s Earliest Building Blocks Found, Named Shiva & Shakti


Scientists of one of the world’s leading astronomy institutes, Germany-based Max Planck Institute for Astronomy, have identified two of the Milky Way’s earliest building blocks and named them“Shakti” and “Shiva”

“These appear to be the remnants of two galaxies that merged between 12 and 13 billion years ago with an early version of the Milky Way, contributing to our home galaxy’s initial growth. The new find is the astronomical equivalent of archeologists identifying traces of an initial settlement that grew into a large present-day city. It required combining data for nearly 6 million stars,” the study said, the results of which have been published in Astrophysical Journal.

Khyati Malhan and Hans-Walter Rix of the Max Planck Institute for Astronomy were the ones who succeeded in identifying the two earliest building blocks that can still be recognised today as “proto-galactic fragments that merged with an early version of our Milky Way at the very beginning of the era of galaxy formation in the universe”. The components were identified by combining data from European Space Agency’s astrometry satellite Gaia with data from the Sloan Digital Sky Survey.

Researcher Malhan has named these two structures Shakti and Shiva, the latter one of the principal deities of Hinduism and the former a female cosmic force often portrayed as Shiva’s consort. “We observed that, for a certain range of metal-poor stars, stars were crowded around two specific combinations of energy and angular momentum. Shakti and Shiva might be the first two additions to the ‘poor old heart’ of our Milky Way, initiating its growth towards a large galaxy,” said Malhan, in a press statement. Rix provided detailed information about the stars’ chemical composition.

Their energy and angular momentum values, plus their overall low metallicity on a par with that of the “poor old heart”, makes Shakti and Shiva good candidates to be some of the earliest ancestors of our Milky Way.
