Astronomers report the discovery of a new sub-Neptune exoplanet as part of the TESS Hunt for Young and Maturing Exoplanets (THYME) program. The newly found alien world, designated HD 110082 b, is about three times larger ...
In order to better understand the composition of rocky exoplanets, researchers have proposed a method to identify chemical signatures from surface materials. A better understanding of exoplanet surface compositions will help ...
