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
