Five years ago, NASA’s infrared Spitzer Space Telescope helped discover a family of seven rocky exoplanets orbiting the same star, known as TRAPPIST-1. Now, NASA’s new infrared powerhouse — the James Webb Space Telescope (JWST) — measured the temperature of one of those worlds, TRAPPIST-1b, in new research published in the journal Nature (opens in new tab) .
The bad news: The Earth-like planet is almost certainly uninhabitable.
Astronomers used JWST’s mid-infrared camera, called MIRI, to look for the planet’s thermal emission — think heat-sensing “Terminator” vision. They found that TRAPPIST-1b is scorching — about 450 degrees Fahrenheit (232 degrees Celsius), about the temperature of an oven — and that it likely lacks an atmosphere.
The discovery is another record-breaking first for the JWST, which has been steadily producing newsworthy results since its launch.

“This is the first detection of any form of light emitted by an exoplanet as small and as cool as the rocky planets in our own solar system,” NASA officials said in a statement (opens in new tab) .
“No previous telescopes have had the sensitivity to measure such dim mid-infrared light,” Thomas Greene (opens in new tab) , a NASA astrophysicist and lead author of the new work, said in the statement.
The initial discovery of the seven TRAPPIST-1 exoplanets spurred great excitement in the astronomical community, since all of the distant worlds are about the size of Earth and are located in their star’s habitable zone, the region that’s just the right distance from a star for liquid water to exist on a planet’s surface. This system is “a great laboratory” and “the best targets we have for looking at the atmospheres of rocky planets,” study co-author Elsa Ducrot (opens in new tab) , an astronomer with the French Alternative Energies and Atomic Energy Commission (CEA), said in the statement.
Don’t get too excited about a new world for humans yet, though — the TRAPPIST-1 planets are out of our current reach, at a whopping 235 trillion miles (378 trillion kilometers) away. They’re also orbiting a star much smaller and redder than our sun, known as an M dwarf star.
“There are ten times as many of these stars in the Milky Way as there are stars like the sun, and they are twice as likely to have rocky planets as stars like the sun,” Greene said.
These abundant M dwarfs are obvious targets for astronomers seeking habitable planets, and it’s conveniently easier to observe rocky planets around these smaller stars. There’s one catch, though: M dwarfs are much more active than our sun, often flaring and spewing high-energy rays that could be damaging to budding extraterrestrial life or to a planet’s atmosphere.related stories—Monster black hole may have killed this galaxy’s star-forming power, James Webb Telescope reveals

Previous observations of TRAPPIST-1b weren’t sensitive enough to determine if it had an atmosphere after all, or if it was a barren rock. The planet is tidally locked to its star, meaning one side always faces its star and the other is stuck in perpetual night. Simulations suggest that if this world had an atmosphere, the planet’s temperature would be lower, as the air would redistribute the heat around both sides. The JWST recorded a significantly hotter temperature, though — indicating no atmosphere and knocking one more planet off humanity’s list of possibly habitable worlds.
The real excitement here, however, isn’t really the specifics of TRAPPIST-1b. Instead, the crucial takeaway is that the JWST is capable of these kinds of measurements and will continue to make more of them, exploring the atmospheres and temperatures of many other worlds.
“There was one target that I dreamed of having, and it was this one,” study co-author Pierre-Olivier Lagage (opens in new tab) , also with CEA, said in the statement. Lagage is one of the developers of MIRI, the instrument that made these observations. “This is the first time we can detect the emission from a rocky, temperate planet. It’s a really important step in the story of discovering exoplanets.”
Sabrina Carpenter has hit out at an “evil and disgusting” White House video of migrants being detained that uses one of her songs.
“Do not ever involve me or my music to benefit your inhumane agenda,” the pop star posted on X.
The White House used part of Carpenter‘s upbeat song Juno over pictures of immigration agents handcuffing, chasing and detaining people.

President Trump‘s policy of sending officers into communities to forcibly round up illegal immigrants has proved controversial, with protests and legal challenges ongoing.
Mr Trump promised the biggest deportation in US history, but some of those detained have been living and working in the US for decades and have no criminal record.
Carpenter is not the only star to express disgust over the administration’s use of their music.

This community in Sri Lanka’s Kandy District is a mass of mud and loss.
The narrow, filthy streets in Gampola are filled with broken furniture, sodden toys and soiled mattresses. A torrent of floodwater ripped through this neighbourhood and many people had no time to escape.
Trying to reach their now destroyed homes is like wading through treacle – the mud knee-deep.
Many locals say they were not warned about the threat Cyclone Ditwah posed here before it struck last Friday, and weren’t told to evacuate. They say they’ve received very little help since.
Resourceful neighbours were left to try to help rescue survivors. But some had to carry the bodies of the dead, too. Mohamed Fairoos was one of them.

“We took five bodies from here,” he says, gesturing to a house full of debris, where mattresses hang drying over the balcony.
“We took nine bodies in total and handed them over to the hospital.” He appears both shocked and exasperated at the lack of support this community received.

“When I took the bodies, the police, the navy, no one sent for us.” He tells me he even posted a video online appealing for boats, hoping it might help.
I ask him if he thinks the government has done enough. “No,” he says forcefully. “No one called for us. No one helped us. No one gave us any boats.”

‘Five people were killed here’
Just a few doors down, a group of volunteers have come to clear another home filled with floodwater. “Five people were killed here,” one of them tells me.
Five of them came from one family: a mother, father, their two daughters and son. Kumudu Wijekon tells me she was friends with them and they’d fled here to a friend’s house, hoping to escape the threat.
“There was heavy rain, but they didn’t think there would be flooding. They left their own home to save themselves from landslides. If they had stayed, they would have survived.”

‘We don’t have a single rupee’
A short drive away, Chamilaka Dilrukshi is sobbing inside the photography studio she shares with her husband Ananda. They have two children aged four and 11.
Chamilaka is clutching a bag of rice – she says it’s been donated by a friend and it’s all they have to eat.

Everything in the shop is wrecked – expensive cameras and lighting equipment covered in thick layers of mud, and outside, rows of broken frames and ripped pictures.
They think they’ve lost nearly £2,500 and their home is severely damaged. She weeps as she tells us: “We don’t have a single rupee to start our business again. We spent all of our savings on trying to build our house.”
Like Mohamed, she believed they should have been warned. “We didn’t know anything. If we did, we would have taken our cameras and our computers out. We just didn’t know it was coming.”

Anger at government’s perceived failings
Sri Lankan president Anura Kumara Dissanayake has declared a state of emergency to deal with the aftermath of the cyclone, and international aid has arrived.
But many people are angry at the government’s perceived failings. It’s been criticised for not taking the warnings from meteorologists seriously two weeks before the cyclone made landfall, as well as for not communicating enough messages in the Tamil language.
It is going to take places like Gampola a long time to rebuild, repair and restore trust. And in a country still recovering from an economic collapse, nothing is guaranteed.

The White House formally announced its plan to hike US fuel costs by $23 billion today, in the form of a new proposed rule cutting fuel efficiency requirements.
Update 12/3: This article has been updated to reflect the formal announcement of the proposed rule.
Since the beginning of this year, the occupants of the White House have been on a mission to raise costs for Americans.
This mission has encompassed many different moves, most notably through unwise tariffs.

But another effort has focused on changing policy in a way that will raise fuel costs for Americans, adding to already-high energy prices.
The specific rollback today focuses on a rule passed under President Biden which would save Americans $23 billion in fuel costs by requiring higher fuel economy from auto manufacturers. By making cars use less fuel on average, Americans would not only save money on fuel, but reduce fuel demand which means that prices would go down overall.
The effort to roll back this rule was initially announced on the first day that Sean Duffy started squatting in the head office of the Department of Transportation. Duffy notably earned his transportation expertise by being a contestant on Road Rules: All Stars, a reality TV travel game show.
Then in June, Duffy formally reinterpreted the Corporate Average Fuel Economy (CAFE) standard, claiming falsely that his department does not have authority to regulate fuel economy.
Republicans in Congress even got into effort to raise your fuel costs, as part of their ~$4 trillion giveaway to wealthy elites included a measure to make CAFE rules irrelevant by setting penalties for violating them to $0. In addition, it eliminated a number of other energy efficiency and domestic advanced manufacturing incentives.
Duffy’s department then told automakers that they would not face any fines retroactively to 2022, which saved the automakers (mostly Stellantis) a few hundred million dollars and cost American consumers billions in fuel costs.
Today, Duffy formally announced the proposed changes to the CAFE rules, lowering the required fuel economy for 2022-2031 model year vehicles, even despite all of the other changes in trying to make the rules unenforceable. The theory behind this would be to make it harder to later enforce the rules, and to allow automakers to get off with more pollution, and to increase fuel demand and fuel prices for longer until a real government returns to power and starts doing its job to regulate pollution.
Specifically, the announcement changes the planned 2031 50.5 mpg target to 34.5 mpg, cutting vehicle efficiency by nearly a third, which will lead to a commensurate increase in your fuel costs.
CAFE targets have been in place since the 1970s. In the last two decades, they helped drive a 30% improvement in average fuel economy, saving an average of $7,000 over the lifetime of an average vehicle – and they did this without increasing vehicle prices.
Rollback supported by auto CEOs who want to increase your costs
Today’s announcement was praised by the CEOs of the Big Three American automakers – GM, Ford, and Stellantis (formerly Chrysler). Ford CEO Jim Farley and Stellantis CEO Antonio Filosa attended the announcement at the White House, along with a manager from GM, though Barra signaled her support while speaking at another event.
Despite both Barra and Farley recently making statements claiming their support for electric vehicles, both cravenly supported the rollback in fuel economy standards that will cost you more money at the pump.
Barra said today that “I’m always going to advocate for one national standard and making sure regulatory requirements don’t get in front of the consumer,” despite the fact that GM lobbied against the single national standard that had been agreed to between Obama and California, and that today’s move only increases the gulf between the federal government and California on auto standards.
And Farley, despite acknowledging that the Chinese are trouncing us on EVs, said today that “we can make real progress on carbon emissions and energy efficiency while still giving customers choice and affordability,” which is detached from reality given that today’s moves will reduce affordability and efficiency and increase carbon emissions.
Their support suggests that their prior commitments to energy efficiency and electrification were not serious, as they are now joining in an effort to increase your fuel costs, just to save themselves a few engineering dollars on having to provide something other than the disgusting, deadly land yachts that are a blight on the nation’s roads and are murdering pedestrians at a 50-year high.
This isn’t the only way the White House is trying to raise your costs
Today’s announcement is just one many efforts currently being undertaken by executive departments to try to raise your fuel costs.
One of the largest is the EPA’s attempt to delete the “Endangerment Finding,” the government’s recognition of the scientific fact that climate change is dangerous to humans. The EPA is undertaking this effort so that it can then eliminate other rules intended to reduce pollution, with the goal of making you more beholden to fossil fuels.
Even the Energy Department’s own numbers, signed off on by oil shill Chris Wright, say that changes sought by the White House will increase gas prices by $.76/gal.
Like most other governmental changes, today’s change will likely go up for public comment, as required by the Administrative Procedures Act. We’ll let you know when it does.
