JWST maps the weather on a hot gas giant 700 light-years away

2026-05-22 03:26:03

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 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 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.

Zillow loses thousands of listings in fight over “hidden” homes

2026-05-22 02:35:38

On Wednesday, Zillow abruptly lost access to thousands of property listings in the Chicago area after filing a lawsuit accusing a private listing network owner of colluding with the nation's largest brokerage to harm consumers by hiding homes.

According to the Chicago Sun-Times, hopeful Chicagoland home buyers browsing Zillow and Trulia suddenly saw significantly fewer listings. On Zillow, a nearly 5,000-home market dropped to about 1,700.

Thorough home buyers diligently checking every possible resource can still turn to other platforms, like Redfin and Realtor.com, which currently host between 5,000 and 8,000 listings, the Sun-Times noted.

Stunning aerial footage still best thing about Top Gun at 40

2026-05-22 00:42:43

When the action film Top Gun hit the big screen in 1986, critical reviews were mixed, but audiences were thrilled. The film racked up $358 million globally, making it the highest-grossing film of that year. Its success spawned a few video games and a critically acclaimed blockbuster 2022 sequel, Top Gun: Maverick, and the eye-popping flight sequences definitely boosted enlistment numbers for the US Navy. Those scenes are still the best thing about Top Gun, 40 years later.

(Spoilers below because it's been 40 years.)

The film was inspired by a 1983 article in California magazine detailing the lives of fighter pilots at Naval Air Station Miramar in San Diego (aka "Fightertown USA") and featuring plenty of aerial photography alongside the text. Producers Jerry Bruckheimer and Don Simpson tapped Jim Cash and Jack Epps Jr. to write the screenplay, with Epps sitting in on declassified classes at the academy and even taking a flight aboard an F-14.

Uh-oh, the International Space Station is leaking again

2026-05-22 00:07:17

NASA confirmed Thursday that the Russian segment of the International Space Station has begun leaking atmosphere into space again. It's an old problem that NASA recently hoped was resolved.

For more than half a decade, engineers from Roscosmos and NASA have been tracking the leak rate from a small Russian module attached to the space station that leads to a docking port. The source of these leaks, microscopic structural cracks, have been difficult to find and address.

In January, NASA said that after multiple inspections and sealant applications, the pressure inside this segment, known as the PrK module, had reached a "stable configuration." The PrK module is essentially a transfer tunnel attached to the Zvezda Service Module on the Russian segment of the space station.

US government takes $2 billion equity stake in nine quantum computing firms

2026-05-21 21:48:38

The US government will take equity stakes worth a total of $2 billion in a slew of quantum computing companies, including a startup backed by a firm with links to the Trump family and one taken public by a Pentagon official.

The announcement by the commerce department that it had signed letters of intent with nine companies—including GlobalFoundries and IBM—sent shares in quantum specialists soaring on Thursday.

Both IBM, which is set to get $1 billion, and GlobalFoundries, which will receive $375 million, were up more than 6 percent in pre-market trading. D-Wave Quantum, an awardee that was taken public in 2022 by Emil Michael—now a top Pentagon official—was up more than 20 percent.

Plug-in hybrids get plugged in more than you might think

2026-05-21 21:34:53

Plug-in hybrid powertrains were developed to be the best of both worlds: a combustion engine and fuel tank that can handle those longer journeys exactly the same as a non-hybrid car, with an electric motor and a battery large enough for most or all of someone's daily driving range. But only if you plug it in. And it is often taken as a statement of fact that plug-in hybrid owners don't plug in their plug-in hybrids.

Instead, they were seduced into buying a car with far too big a battery, no doubt as a result of generous incentives, the theory goes. And if those drivers aren't going to plug in and therefore enjoy at least some entirely electric driving, they should have bought a parallel hybrid instead, which often delivers better efficiency than a PHEV with an empty battery, at a significantly lower price.

But what if that take is wrong? As it turns out, there's some more evidence that PHEV drivers do in fact plug in their plug-ins, and the latest data point is from one of the most prolific PHEV pushers: Toyota.
