US EditionJames Webb Space Telescope finds strongest evidence yet for atmosphere around rocky exoplanet: 'It's really like a wet lava ball'
JWST observations show TOI-561 b’s dayside temperature is 1,700–1,800 °C, cooler than expected, indicating a thick volatile-rich atmosphere above a global magma ocean.

James Webb Space Telescope finds strongest evidence yet for atmosphere around rocky exoplanet: 'It's really like a wet lava ball'
The James Webb Space Telescope has found the strongest evidence yet of an atmosphere around a rocky exoplanet, challenging assumptions that ultra-hot super-Earths cannot hold onto air.

The planet TOI-561 b, an ultra-hot super-Earth located outside our solar system, is surrounded by a thick layer of gases covering a global ocean of magma—the strongest evidence yet of an atmosphere on a rocky exoplanet. The discovery, made by a team from the University of Birmingham (UK), was made possible by observations from the James Webb Space Telescope (JWST), operated by NASA, ESA, and CSA. According to the authors, this atmosphere would e…
The super earth TOI-561 b contradicts expectations. Researchers use the Webb telescope and find a thick atmosphere on the ultra-hot rock planet. The article Atmosphere despite Hell Heat: The paradoxical secret of TOI-561 b first appeared on ingenieur.de - Job Market and News Portal for Engineers.
NASA’s Webb Detects Thick Atmosphere Around Broiling Lava World
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. A world whose dayside temperature is so high that the surface must now be a sea of liquid hot magma. Conventional wisdom might suggest that a planet like this is far too small and hot to hold on to an atmosphere. But new results from NASA's James Webb …
