Habitable Zone

• Astronomers have confirmed the first atmosphere around a rocky planet located in its star's habitable zone, identified as LHS 1140 b. • Located 48 light-years away, the planet's atmosphere was detected by observing helium slowly leaking into space. • This discovery is significant because the world may have preserved its atmosphere for billions of years, increasing the likelihood of habitability.

• Astronomers have discovered an atmosphere containing helium on LHS 1140b, a rocky planet located 48 light-years away. • The planet is situated within its star's habitable zone, suggesting the potential for liquid water to exist on its surface. • This finding, published this week in the journal Science, marks a significant milestone in the search for life-friendly environments outside our Solar System.

• Astronomers have confirmed the presence of an atmosphere on LHS 1140 b, a rocky exoplanet located 48 light-years from Earth. • The planet is situated within its star's habitable zone, making it a primary candidate for studying the potential for liquid water and life. • This discovery is significant as it may be the first rocky planet in a habitable zone to have a confirmed atmosphere, a major milestone in two decades of exoplanet research.
