Light patterns suggest the blue supergiant HD 74371 is growing hotter after a past red-supergiant phase. Elsewhere, planets show striking atmospheric weather and escaping helium, while infrared observations reveal a star’s vibrations and a young system’s magnetic activity.

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.
