An international team of astronomers reports the detection of four new giant alien worlds as part of the HATSouth photometric survey. The newfound exoplanets are the size of Jupiter and received designations HATS-74Ab, HATS-75b, ...
Astronomers have a new tool to help them understand giant stars. It's a detailed study of the precise temperatures and sizes of 191 giant stars. The authors of the work say that it'll serve as a standard reference on giant ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new inflated, low-density "hot Jupiter" exoplanet. The newly found alien world, designated TIC 257060897b, is about 50 percent larger ...
A team of space scientists has published a paper in Annual Review of Astronomy and Astrophysics suggesting that there may be an Earth- or Mars-sized planet orbiting beyond Neptune. They further suggest that simulations of ...
