Astronomers have, for the first time, confirmed an atmosphere around a rocky planet located within its star’s habitable zone. The discovery centers on LHS 1140 b, a world approximately 48 light-years from Earth.
The planet, LHS 1140 b, revealed its atmospheric presence through the detection of helium slowly escaping into space. This finding marks a significant step forward in the search for potentially habitable planets beyond our solar system. Researchers believe this atmosphere may have been preserved for billions of years.
The team’s findings indicate that LHS 1140 b is a promising target for further investigation. The presence of an atmosphere, even one slowly leaking into space, suggests conditions could be conducive to supporting life as we know it. This discovery provides valuable insight into the composition and evolution of planetary atmospheres outside our solar system.
