"Mit .. CHEOPS ist es .. gelungen, die Existenz von vier neuen Exoplaneten eindeutig zu bestätigen. Die .. Mini-Neptune sind kleiner und kühler + daher schwieriger zu finden als die sogenannten Heissen Jupiter, .. Zwei der vier Studien stammen von Forschenden der Uni Bern und der Uni Genf, ..

#astronomy #exoplanets #MiniNeptune #Hubble #Spitzer NASA used the Hubble e Spitzer space telescopes to study the composition of the atmosphere of Gliese 3470 b, a mini-Neptune that orbits very close to its star, which is a red dwarf but still heats it up to temperatures that are estimated on the surface between 700 and 900 Kelvin. https://english.tachyonbeam.com/2019/07/04/a-study-of-the-atmosphere-of-the-exoplanet-gliese-3470-b
