A rocky planet about 49 light-years from Earth appears to have held onto an atmosphere, despite orbiting a red dwarf capable of stripping gases into space. The evidence comes from helium escaping ...

Science has discovered around 6,000 planets, and this is the first one, other than Earth, that is rocky and has an atmosphere. The search for life beyond Earth has borne little fruit. That remains ...

Astronomers have detected escaping helium gas around LHS 1140 b, a rocky super-Earth orbiting in the habitable zone of a ...

Scientists say exoplanet LHS 1140b shows promising signs that it could have an atmosphere, making it potentially suitable for ...

In a major milestone in the search for life on other planets, astronomers have detected, for the first time, an atmosphere ...

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's habitable zone. Water is a key ingredient for life, and on a planet too close to ...

Dreams of finding a sort of Earth 2.0 motivate much of the thinking around the search for exoplanets. But there is more to exoplanet science than searching for potentially habitable worlds. Scientists ...

A rocky world orbiting within its star’s habitable zone may be surrounded by a helium-rich atmosphere, providing the strongest evidence yet that planets with Earth-like conditions could support life ...

Like a toddler right before naptime, TRAPPIST-1 is a small yet moody star. This little star, which sits in the constellation Aquarius about 40 light-years from Earth, spits out bursts of energy known ...

How much water do habitable exoplanets need for life as we know it to exist? This is what a recent study published in The Planetary Science Journal hopes to address as a team of scientists ...

Scientists have uncovered a surprising way to study the harsh space weather around young M dwarf stars. Mysterious dips in starlight turned out to be massive rings of plasma swirling in the stars’ ...
