(Phys.org)—Astronomers have detected four new giant exoplanets as part of the Hungarian-made Automated Telescope Network-South (HATSouth) exoplanet survey. The newly found alien worlds are about the size of Jupiter, but ...
When astronomers first discovered other planets, they were completely unlike anything we've ever found in the Solar System. These first planets were known as "hot Jupiters", because they're giant planets – even more massive ...

(Phys.org)—An international team of astronomers led by Joel Hartman of Princeton University has detected two new "hot Jupiter" exoplanets, less massive than our solar system's biggest planet, but with a radius larger than ...
California Institute of Technology (Caltech) astronomers using data gathered at the W. M. Keck Observatory have developed a new technique for planetary scientists that could provide insight into how many water planets like ...

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 ...
Gemini Observatory's Planet-Finding Campaign finds that, around many types of stars, distant gas-giant planets are rare and prefer to cling close to their parent stars. The impact on theories of planetary formation could ...
