Event Summary

Astronomers have detected, for the first time, an atmosphere surrounding an Earth-like, rocky planet orbiting within the habitable zone of another star. The planet, LHS 1140 b, is located 48 light-years away and orbits a red dwarf star. Using the WINERED spectrograph on the List of observatory codes in Chile, researchers observed helium escaping from the planet's atmosphere, confirming its presence. The discovery, led by Collin Cherubim of Harvard University, was published in the journal Science. The planet's atmosphere has likely survived for billions of years, making it a prime target for future habitability studies. This finding validates new methods for detecting atmospheres on rocky worlds and suggests many more such planets may exist.
