Description
Stars in bulge of Milky Way, Hubble Space Telescope (HST) image. The crowded ancient central hub or bulge of the Milky Way contains ageing red giant stars and more plentiful younger and smaller, white, Sun-like stars. Most of the bright blue stars are in the foreground are recently formed stars in the galactic disc. Within the bulge, stars richer in elements heavier than hydrogen and helium are orbiting around the galactic centre faster than older stars that are deficient in heavier elements. This composite of infrared and visible light was obtained with the HST's Wide Field Camera 3 (WFC3). The observations are part of two Hubble surveys: the Galactic Bulge Treasury Program (GBTP) and the Sagittarius Window Eclipsing Extrasolar Planet Search (SWEEPS). The galactic centre is 26,000 light years away in the constellation of Sagittarius. Image published in 2018.
