NASA's Hubble Space Telescope has uncovered a large, rare population of hot, bright stars in the core of the neighboring Andromeda galaxy. Astronomers used Hubble's Wide Field Camera 3 to find roughly 8,000 of the ultra-blue stars in a stellar census made in ultraviolet light, which traces the glow of the hottest stars.
