Astronomers Discover First Atmosphere on Rocky Planet in Habitable Zone

21 Temmuz 2026Science Daily

Astronomers have discovered the first confirmed atmosphere surrounding a rocky planet located in the habitable zone of another star. This planet, known as LHS 1140 b, has shown signs of an atmosphere through the detection of helium escaping into space.
Situated 48 light-years from Earth, it is believed that LHS 1140 b may have maintained its atmosphere for billions of years, positioning it as a significant candidate in the ongoing search for habitable worlds.
The search for exoplanets in habitable zones has intensified in recent years, with astronomers focusing on planets that may possess conditions suitable for life. The confirmation of an atmosphere on LHS 1140 b adds to the growing body of evidence that rocky planets can maintain atmospheres, which is essential for th…
The discovery of an atmosphere on LHS 1140 b marks a pivotal moment in exoplanet research, as it provides crucial insights into the conditions that may support life beyond Earth. The presence of helium leakage suggests dynamic atmospheric processes, which could indicate a complex interaction between the planet's geo…
