WASP-94A b is a hot, tidally locked gas giant orbiting close to one of the stars in a binary system roughly 690 light-years away from Earth. In a new Science study, scientists led by Sagnick Mukherjee, an astrophysicist at Johns Hopkins University, used the James Webb Space Telescope to learn what the weather looks like out there.

Tidal locking means that you no longer have day- and night-side temperature differences sweeping across the planet. “We wanted to understand the atmospheres of such planets,” Mukherjee says. “Are they static or dynamic? Do they have winds? Do they have clouds?” His team found that, on WASP-94A b, it’s cloudy in the morning, but the skies are clear in the evening. The fact that we didn’t know this already means we might have gotten the chemistry of this and many other exoplanets surprisingly wrong.

Averaged atmospheres

WASP-94A b has a mass slightly below half of Jupiter but has a diameter that’s over 70 percent wider. “This means the planet has low density, and its atmosphere extends further out into space, which makes it easier to observe,” Mukherjee explains. When astronomers study atmospheres like this, they usually rely on transmission spectroscopy. By analyzing the spectrum of light filtering through the planet’s atmosphere as it crosses in front of its star, they can figure out its chemical composition.

NASA's Psyche spacecraft returns unfamiliar views of a familiar world

NASA's Psyche spacecraft returns unfamiliar views of a familiar world

fivenewscrypto    mai 22, 2026   

Not quite halfway through a six-year sojourn through the Solar System, a NASA spacecraft used a close encounter with Mars last week as a dress rehearsal for its arrival at the Solar System's largest metal asteroid in 2029.

The Psyche mission launched more than two-and-a-half years ago, in October 2023, from Kennedy Space Center, Florida, to kick off a journey of some 2.2 billion miles (3.6 billion km) to reach its unexplored namesake, the asteroid Psyche. The robotic research mission got an initial lift from a powerful SpaceX Falcon Heavy rocket. It uses plasma engines to gradually build up the impulse needed to reach its destination in the asteroid belt, between the orbits of Mars and Jupiter.

A flyby of Mars last Friday gave the spacecraft its most significant boost since launch. Navigators at NASA's Jet Propulsion Laboratory in California set up the spacecraft for a course taking it 2,864 miles (4,609 km) from the Martian surface, well above the planet's tenuous atmosphere. Psyche used Martian gravity like a slingshot to gain enough speed to reshape its orbit around the Sun, putting the probe on a path to intercept its asteroid target.

Leaving the V8 in the past: The all-electric Mercedes-AMG GT 4-Door

Leaving the V8 in the past: The all-electric Mercedes-AMG GT 4-Door

fivenewscrypto    mai 22, 2026   

At a star-studded event that closed downtown Los Angeles' Sixth Street Viaduct last night, Mercedes and AMG unveiled the next generation of performance electric vehicles. The new four-door GT Coupe arrives in the midst of a pivotal period, the result of an almost experimental process that seems to take two steps forward and one step back quite regularly. In many ways, the all-electric AMG leaves previous plans in the past by effectively bringing the record-setting Concept AMG GT XX to series production, with many firsts for Mercedes supporting the abandonment of internal combustion power, including new axial motors from YASA and F1-derived battery cells.

Fittingly, then, Mercedes brought out its F1 team’s personnel, as George Russell presented the new car while Toto Wolff and Kimi Antonelli watched from the makeshift grandstands. Hollywood celebs ran the gamut, from Brad Pitt—who drove one GT onto the bridge—to Jacob Elordi and Kevin Hart, while Blink 182 played a surprisingly sarcastic mini set. All of the above may mean less to potential GT buyers than performance metrics and pricing when the 2027 model year comes along, but it only serves to prove just how big a deal Mercedes-AMG believes this will be.

A new look

In person, the new GT bears almost no resemblance to any of Benz’s prior EVs. No more bulbous, nautical EQS shapes or minorly smoothed over boxy G-Wagen aesthetic. The new design is more aided by digital renderings and iterative algorithms, especially the jutting front grille, reclined headlights, and Kamm-tail rear end—a bit of Aston Martin fore and aft. From the profile view, the proportions fit somewhere between a Porsche Panamera or Taycan, low-slung and slippery for ideal aerodynamic efficiency.

Trump wants $1B to protect White House ballroom from drones and other threats

Trump wants $1B to protect White House ballroom from drones and other threats

fivenewscrypto    mai 22, 2026   

President Donald Trump’s latest pitch for using taxpayer dollars to secure his White House ballroom featured a militarized building—including a rooftop hardened against drone strikes and a “drone port” that could potentially house military drones.

The remarks came on May 19 as Trump gave reporters a personal tour of the ballroom project that has already involved the demolition of the White House mansion’s East Wing. The president spoke of installing a rooftop drone base “for unlimited numbers of drones” operated by the US military as a “drone port that would protect all of Washington,” according to Reuters. He also highlighted a ballroom roof made from “impenetrable steel” that would supposedly be “drone-proof” against potential drone strikes.

To pay for such measures, Trump has been urging Republican lawmakers in the US Congress to approve $1 billion in taxpayer funding to provide a wide variety of “security adjustments and upgrades” for his ballroom project. The taxpayer-backed security enhancements would be separate from the $400 million construction cost for the ballroom project that has been funded by private donors, including companies such as Amazon, Apple, Coinbase, Comcast, Google, HP Inc., Lockheed Martin, Meta, Micron Technology, Microsoft, Palantir, Ripple, and T-Mobile.

Hulu set to keep existing as standalone streaming service and app (for now)

Hulu set to keep existing as standalone streaming service and app (for now)

fivenewscrypto    mai 22, 2026   

Disney currently has no plans to shutter Hulu as a standalone streaming service or app, according to a company representative.

In a report from Variety today, the spokesperson said that Disney, which took total ownership of Hulu in June 2025, will continue to sell subscriptions to Hulu in the US and that “there are no current plans to sunset the Hulu app.”

Disney owned two-thirds of Hulu before closing its acquisition of the streaming service’s remaining third from Comcast last year. Since then, some reports have suggested that the Hulu app would be phased out in 2026, while others have speculated that Disney would likely, but not definitely, shutter Hulu. Disney’s statement today means that people should be able to continue watching stuff on Hulu without having to pay for Disney+ for the foreseeable future; although, Disney is free to change its mind at any point.

Minnesota prohibits prediction markets, promptly gets sued by Trump admin

Minnesota prohibits prediction markets, promptly gets sued by Trump admin

fivenewscrypto    mai 21, 2026   

The Trump administration yesterday sued Minnesota in an attempt to block the first state law that prohibits prediction markets.

While other states imposed restrictions on prediction markets, Minnesota banned them outright in a law signed by Gov. Tim Walz on Monday. The US Commodity Futures Trading Commission announced a lawsuit against the state, saying that Minnesota's "new legislation represents the most aggressive move by a state to shut down CFTC-regulated markets and undermine the federal regulatory regime set up by Congress more than 50 years ago."

“This Minnesota law turns lawful operators and participants in prediction markets into felons overnight,” CFTC Chairman Michael Selig said. “Minnesota farmers have relied on critical hedging products on weather and crop-related events for decades to mitigate their risks. Governor Walz chose to put special interests first and American farmers and innovators last.”

Russia's plan to advertise on rockets and spacecraft takes off

Russia's plan to advertise on rockets and spacecraft takes off

It's difficult to know the true state of the Russian economy, both because the country's financial reporting is sparse and because official figures are unreliable. But things probably aren't great.

This week, Sweden's minister of foreign affairs, Maria Malmer Stenergard, shared her country's assessment that the Russian economy has likely contracted over the last five years amid the war in Ukraine. Inflation is also high, and international sanctions have cost Russia $450 billion since the onset of the war in February 2022. Russia's economy is currently smaller than that of Texas, Stenergard said.

By most measures, then, the economy is not in tip-top shape. Moreover, the war is draining a large amount of the country's financial resources, with defense spending reaching a post-Soviet record of about 7 percent of government spending.
