An exoplanet in the Trappist star system — a multi-planet star system similar to the solar system and just 39 light-years distant — may have an atmosphere after all.
An Earth-sized planet in a star system very similar to our solar system may have an atmosphere after all, suggests new research using the James Webb Space Telescope.to have seven potentially Earth-like rocky planets orbiting its star — including three in the not-too-hot, not-too-cold"habitable zone." At just 39 light-years distant, Trappist -1 is also close enough for astronomers to study using space telescopes.
An airless planet with a surface that shows no signs of weathering, which could indicate geological activity such as volcanism and plate tectonics. The uncertainty of the new results is indicative of how difficult it is for scientists to characterize the nature of exoplanets — planets that orbit a star other than our sun — from multiple light-years distant.in 2023, of Trappist-1 b at 15 microns — again using JWST — suggested that a thick, carbon dioxide-rich atmosphere was unlikely. It proposed a"dark bare rock" scenario for the planet. The new study, which added observations at 12.
