Astronomers have made a groundbreaking discovery: the first confirmed atmosphere around a rocky exoplanet situated within the habitable zone of its star. This intriguing planet, known as LHS 1140 b, unveiled its atmospheric presence through the gradual escape of helium into the cosmos. Situated a mere 48 light-years away, LHS 1140 b might have remarkably maintained its atmosphere over billions of years, positioning it as a compelling candidate in the quest to find planets that could potentially support life.
