Using ESO/MPG telescope in Chile, a team of astronomers has detected an atmosphere around an Earth-like planet for the first time. The planet, super-Earth planet GJ 1132b, is located 39 light-years away.
Researchers have detected an atmosphere around the super-Earth planet GJ 1132b. This marks the first detection of an atmosphere around an Earth-like planet other than Earth itself, and thus is a significant step on the path towards the detection of life outside our Solar System. The team that made the discovery, led by Keele University’s Dr John Southworth, used the 2.2 m ESO/MPG telescope in Chile to take images of the planet’s host star GJ 1132. They were able to measure the slight decrease in brightness as the planet and its atmosphere absorbed some of the starlight while transiting (passing in front of) the host star.
