LHS 1140 b: Atmosphere Detected for the First Time on an Earth-like Rocky Exoplanet in the Habitable Zone

For the first time, an atmosphere has been detected around a rocky exoplanet: strong evidence for life beyond Earth.

Astronomers have made a groundbreaking discovery: they detected an atmosphere around LHS 1140 b, a rocky, Earth-like planet orbiting in the habitable zone of another star.

This finding provides the strongest evidence to date for the existence of worlds beyond our Solar System with Earth-like conditions, capable of supporting liquid water and life.

The detection of helium escaping from the planet's atmosphere indicates that it has been retained for billions of years.
