INBOX ASTRONOMY NASA’s Webb Detects Thick Atmosphere Around Broiling Lava World  Release date: Thursday, December 11, 2025 10:00:00 AM Eastern Standard Time Observations of the ultra-hot super-Earth exoplanet TOI-561 b show the strongest evidence yet for an atmosphere on a rocky planet outside our solar system. Imagine a rocky world that has spent billions of years in the blazing light of a star so close it spans a quarter of the planet’s sky. A world where a year lasts 11 hours, but the day never ends ...Continue Reading

INBOX ASTRONOMY NASA’s Webb Identifies Earliest Supernova to Date, Shows Host Galaxy Release date: Tuesday, December 9, 2025 11:00:00 AM Eastern Standard Time The telescope captured near-infrared light from one of the earliest stars seen to explode in the history of the universe. With a few near-infrared snapshots, the James Webb Space Telescope nailed down the source of a super bright flash of light known as a gamma-ray burst, generated when a massive star exploded when the universe was only 730 million ye ...Continue Reading
