Webb Discovers Fiery Super-Earth Clinging to Air Against All Odds

Astronomers have discovered a super-Earth located 280 light-years away in the Sextans constellation. Called TOI-561 b, a day there lasts only 11 hours because it is so close to its star. That said, you would expect the surface to be a giant ball of heat, yet it is still maintaining a thick layer of gas [...]

JWST may have found a thick atmosphere in an unexpected place — an ultra-hot super-Earth

A tightly orbiting planet in another star system is overturning long held ideas about what small, super heated worlds can keep around them. TOI 561 b circles its star in less than half a day and faces temperatures high enough to melt rock, yet new observations from the James Webb Space Telescope show strong evidence for a dense atmosphere. The finding challenges common expectations about how extreme light and heat strip gases from planets over t…
