A blue supergiant’s changing light reveals that it is moving back toward hotter temperatures after a red-supergiant phase. New findings also trace infrared ripples on WASP 121, map the uneven clouds of WASP-43 b, and reveal helium escaping ahead of TOI-3884 b. Meanwhile, observations of the young star V1298 Tauri show how magnetic activity can make a star brighten and fade across radio and X-ray light.

More about Star position in StellarGuide
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.
