Atmosphere Detected on Earth-Like Planet for the First Time

Scientists have made a significant breakthrough in the search for life in the universe. The rocky planet LHS 1140 b, located approximately 50 light-years from Earth, has been found to have an atmosphere composed mostly of helium. This is the first direct detection of an atmosphere on an Earth-like planet in the habitable zone.According to the research, LHS 1140 b has been exposed to high levels of X-ray and ultraviolet radiation since its formation. However, the planet has managed to retain a significant portion of its initial helium, allowing its atmosphere to persist to the present day. This suggests that the planet has maintained a stable atmospheric structure over a long period.LHS 1140 b is thought to have a thin atmosphere composed mostly of helium. The planet's mass and radius, as well as its location in the habitable zone, make it a promising candidate for hosting liquid water.
