A helium plume racing ahead of TOI-3884 b and infrared flickers from WASP 121 reveal surprising details about distant worlds and their stars. New work also maps the cloudy weather of WASP-43 b and traces massive HD 74371’s return to a blue-supergiant phase, while search interest highlights Proxima Centauri, Alpha Centauri, and other stellar favorites.

Data in Stellar Catalog come from trusted scientific sources. Primary source is Gaia space telescope mapping the stars in Milky Way. Other sources include research papers, Simbad catalog and Exoplanet.eu database.
Objects listed in the Stellar Catalog often have values that are estimates. These estimates are determined using their known characteristics, such as spectral type, brightness across different wavelengths, distance from a star, and other factors.
Stellar Catalog is continuously updated with new information from research papers. Stellar and planetary data are validated by automatic processes as well as humans.
