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.”

Cyclones name WSU's Rogers to replace Campbell

Washington State coach Jimmy Rogers has agreed to a six-year deal to become the next coach at Iowa State, the school announced Friday.

Iowa State athletic director Jamie Pollard moved quickly to replace departing coach Matt Campbell, who agreed to an eight-year deal to take over Penn State on Friday, and landed Rogers, a proven winner at the FCS level who just concluded his first regular season at Washington State.

“Jimmy Rogers is a rising star in college athletics who has very strong ties to the Midwest both as a player and as a coach,” Pollard said in a statement. “He has been on my short-list ever since the first time I met him. He immediately impressed me with his interest in Iowa State University and told me during our first visit several years ago that he wanted to be the next head coach at Iowa State.

“Since our initial meeting, I have stayed in close contact with him and have been very impressed with his work ethic and understanding of what it takes to be successful at Iowa State,” Pollard added. “He is a proven winner who has demonstrated throughout his career that he will fit our culture.”

Rogers, 38, has a 33-9 record over three seasons as a head coach. He went 6-6 in his debut season at Washington State after overseeing a significant roster rebuild following the departure of coach Jake Dickert to Wake Forest.

“My family and I are excited to be joining the Iowa State University community and the Cyclone football program,” Rogers said in a statement. “Iowa State has been one of the nation’s top programs for the last decade and we look forward to building upon its upward trajectory. I’m extremely grateful for the opportunity that Jamie Pollard has given me to lead the Cyclones.”

Rogers previously spent 12 years at South Dakota State and led his alma mater to an FCS national championship in 2023 with a 15-0 season in his first year as the Jackrabbits’ head coach after taking over for longtime coach John Stiegelmeier.

Rogers carried a 29-game win streak into his second year as coach and achieved a No. 3 finish in 2024 with a run to the FCS playoff semifinals and a 12-3 season.

The Jackrabbits also won the FCS national championship in 2022 after Rogers was elevated to being the team’s sole defensive coordinator, and they played for another FCS title in 2020.

Campbell, the winningest coach in Iowa State history with 72 victories, led the Cyclones to eight winning seasons during his decade at the helm and two appearances in the Big 12 championship game.

The Cyclones went 8-4 this season and are awaiting their bowl selection on Sunday.

Cool it! JMU AD scolds fans for throwing snowballs

HARRISONBURG, Va. — James Madison athletic director Matt Roan used the public-address microphone to implore Dukes fans to stop throwing snowballs onto the field during the Sun Belt Conference championship game against Troy on Friday night, warning that their actions could cost JMU a penalty.

Roan’s address to the crowd followed an incident that affected the game.

With 4:30 left in the first quarter, Troy’s Evan Crenshaw was nearly hit by a snowball while punting from the end zone with the JMU student section behind him. Crenshaw shanked a 26-yard punt that helped set up the Dukes’ first score, a 40-yard field goal.

Fans in the student section began throwing snowballs during pregame warmups, when the Dukes’ marching band got pelted. They kept it up for most of the first half, despite repeated warnings over the PA system.

Harrisonburg received about 1½ inches of snow Friday, its first measurable snowfall of the season.

No. 19 JMU had an outside shot at making the College Football Playoff field with a win over Troy and a loss by No. 16 Virginia to Duke in Saturday’s Atlantic Coast Conference championship game.

No. 1 recruit DT Lamar Brown signs with LSU

LSU and coach Lane Kiffin closed a busy early signing period with a bang Friday, officially securing the signature of defensive tackle Lamar Brown, ESPN’s No. 1 overall 2026 recruit.

Brown, a 6-foot-5, 285-pound defender from Erwinville, Louisiana, signed his letter of intent on the final day of the three-day period, the program announced, formally joining Kiffin and the Tigers as the program’s first No. 1 overall addition since Leonard Fournette in 2014.

Committed to the program since July, Brown was not initially expected to sign this week following meetings between Brown’s representatives and members of the LSU staff Tuesday.

While Brown remained verbally committed to the program, sources told ESPN that his camp harbored reservations over Kiffin’s to-be-completed coaching staff. Uncertainty hanging over the futures of Tigers interim coach Frank Wilson and defensive coordinator Blake Barker marked a particular concern for Brown, who attends high school on the LSU campus and developed close relationships with the program’s previous staff during his recruitment.

As of Friday afternoon, the Tigers have not publicly announced plans for the program’s defensive staff. The statuses of Wilson and Baker, a reported candidate for multiple head coach openings across the country, remain unclear, too. But according to ESPN sources, Brown and the Tigers progressed toward his signing through talks across Wednesday and Thursday, culminating in the program officially landing his signature Friday afternoon.

Within an impressive Tigers defensive class in 2026, Brown was not alone in initially holding off on signing this week before ultimately submitting the official paperwork.

LSU officially announced the signing of ESPN 300 defensive tackle Richard Anderson (No. 90 overall) on Thursday after questions swirled over his signature on the opening day of the signing period. Top 60 defensive linemen Deuce Geralds (No. 39) and Trenton Henderson (No. 60) each pushed their signings to Friday. Henderson, amid late flip efforts from Auburn and Florida State, gave the Tigers his signature Friday morning. Geralds, ESPN’s No. 2 defensive tackle in 2026, followed in the afternoon, minutes before the program announced Brown’s signing.

For Kiffin, who officially arrived Sunday, Brown’s signature closes LSU’s class of ESPN 300 additions and marks a strong finish to a hectic first week on the recruiting trail with the Tigers.

Uncertainty surrounding Brown and the program’s top defensive pledges hung over early-week commitments from wide receiver Brayden Allen and former Ole Miss pledges J.C. Anderson (No. 165 in the ESPN 300) and Ryan Miret. Pass catcher Corey Barber, another ex-Rebels commit, also signed with the Tigers on Wednesday. LSU also lost five commitments following Kiffin’s arrival, headlined by safety Dylan Purter (No. 266), who flipped to Florida on Thursday.

Kiffin & Co. took some big swings, as well. Sources tell ESPN that the Tigers made late efforts to flip USC tight end signee Mark Bowman (No. 29 overall) and four-star South Carolina quarterback signee Landon Duckworth (No. 186). LSU also attempted to sway No. 1 wide receiver Chris Henry Jr., who affirmed his pledge to Ohio State and signed Friday.

With Brown officially in the fold, the Tigers will close the early signing period with the nation’s No. 14 signing class in ESPN’s latest class rankings for the cycle.
