First atmosphere detected on habitable-zone rocky exoplanet LHS 1140-b

Astronomers have detected an atmosphere around the rocky exoplanet LHS 1140-b, marking a significant breakthrough in the search for extraterrestrial life. This is the first time an atmosphere has been confirmed on a rocky planet within its star's habitable zone, a critical condition for supporting life. The planet, located 48 light-years away, is about 5.6 times the mass of Earth and its atmosphere is primarily composed of helium, detected using the WINERED Spectrograph. AI

IMPACT This discovery advances the search for extraterrestrial life by confirming a key condition for habitability on rocky exoplanets.

RANK_REASON The cluster reports on a scientific study detailing the detection of an atmosphere around an exoplanet, which is a research milestone. [lever_c_demoted from research: ic=1 ai=0.1]
