Study suggests TRAPPIST-1b may have carbon dioxide-rich atmosphere

A new study suggests that TRAPPIST-1b, the closest planet in the TRAPPIST-1 system, may have a carbon dioxide-rich atmosphere. This finding, published on December 16, is based on data showing a reflective haze in the planet's upper atmosphere. Previously, scientists believed TRAPPIST-1b lacked an atmosphere due to strong stellar radiation. However, new measurements from the James Webb Space Telescope indicate the presence of this haze, which may emit radiation instead of absorbing it. The research also points to higher surface temperatures, hinting at possible volcanic activity. Ongoing studies will further investigate the planet's heat distribution and the potential existence of an atmosphere.
