Cool! This is a well-known technique for detecting atmospheres of objects outside our solar system, but this is the first time it’s been used for an object so small (40% bigger diameter than our Earth).

Breaking: Atmosphere around super-Earth detected!
Gliese 1132 b is 1.6 Earth Masses, orbiting red dwarf GJ 1132 and is located only approximately 39 light years away!
“Astronomers have detected an atmosphere around the super-Earth GJ 1132b. This marks the first detection of an atmosphere around an Earth-like planet other than Earth itself, and thus a significant step on the path towards the detection of life on an exoplanet. The team, which includes researchers from the Max Planck Institute for Astronomy, used the 2.2 m ESO/MPG telescope in Chile to take images of the planet’s host star GJ 1132, and measuring the slight decrease in brightness as the planet and its atmosphere absorbed some of the starlight while passing directly in front of their host star.”

Chris…this photograph is totally different and beautiful…
it is so exciting to know such a place exist. The host star is close to this planet right? Is it as close as our moon is to us?…thanks for sharing your knowledge with us…tell us more…anytime…
An atmosphere of what gases ?
juergen bertram unknown so far. We just see that it’s translucent shadowing it’s star sometimes.
Asphyxiating atmosphere ?
If it is 39 light years away, how long does it take us to reach it ?
Alpha Centauri is 4.3 light years away, therefore our closest neighbour !
500°F=260°C, so that would cook your dinner well !
Very Nice .
Beauityful ,are they ever gonna get on it
What’s that in simple terms
I don’t believe there is intelligent life on any of those planets. Why would there planet be any different than ours?
This is amazing its so bright.
