Helium Escaping from Atmosphere of Nearby Rocky Exoplanet in Habitable Zone

Helium escaping from atmosphere of nearby rocky exoplanet in a habitable zone

We detected helium escaping from the atmosphere of a nearby rocky exoplanet located in the habitable zone. This discovery suggests that even Earth-like worlds can lose their atmospheres over time, challenging our understanding of planetary longevity and the potential for life beyond our solar system.

"Even a rocky planet in the habitable zone is not guaranteed to keep its atmosphere forever."
