This artist’s concept shows the volatile red dwarf star TRAPPIST-1 and its four most closely orbiting planets, all of which have been observed by NASA’s James Webb Space Telescope (JWST). JWST has ...

A new study modeled the chemistry of TOI-270 d, an exoplanet between Earth and Neptune in size, finding evidence that it could be a giant rocky planet shrouded in a thick, hot atmosphere. TOI-270 d is ...

A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...

The atmospheres of alien planets can now be probed even if they are not illuminated by stars directly behind them, astronomers say. A new method used to scan the atmosphere of a distant "hot Jupiter" ...

In a big universe with vanishingly few signs of life, the TRAPPIST-1 system is rich with possibilities. The system is home to seven rocky planets, all of which are earth-sized and likely to have ...

New research using NASA's powerful JWST telescope has identified a planet 41 light years away which may have an atmosphere. The planet is within the "habitable zone," the region around a star where ...

"I had been waiting my entire career for Webb so that we could meaningfully characterize the atmospheres of these smaller planets." When you purchase through links on our site, we may earn an ...
