TRAPPIST-1b Could Have Carbon Dioxide-Rich Atmosphere, Study Reveals 54m4d

The innermost astronomers since its discovery in 2017. Earlier studies suggested that these planets lacked atmospheres due to intense stellar radiation. However, recent data from the James Webb Space Telescope (JWST) raises the possibility of a hazy, carbon dioxide-heavy atmosphere on TRAPPIST-1b.

As per atmosphere, whether it exists or not.

The research also indicates elevated surface temperatures, suggesting potential volcanic activity. Similar dynamics have been observed on Saturn's moon Titan. According to Michiel Min from the SRON Netherlands Institute for Space Research, who contributed to the study, in a statement, the atmospheric chemistry of TRAPPIST-1b is expected to be unlike anything seen on Titan or in the solar system.

The team aims to examine heat distribution across the planet's surface to determine whether an atmosphere is present. Michaël Gillon, an astronomer at the University of Liège who led the discovery of the TRAPPIST-1 system, explained to Nature Astronomy that an atmosphere would facilitate heat redistribution from the day to night side of the planet. Without it, heat transfer would be minimal.
These findings may reshape understanding of atmospheres around exoplanets near red dwarf stars, according to experts.
