  1. NASA's Hubble Traces Hidden History of Andromeda Galaxy

    January 16, 2025Release ID: 2025-005 Missions: Hubble

    Panorama of Nearest Galaxy Unveils Hundreds of Millions of Stars

    The Andromeda galaxy, a spiral galaxy, spreads across the width. It is tilted nearly edge-on to our line of sight so that it appears as an extreme oval on its side. The borders of the galaxy are jagged because the image is a mosaic of smaller, square images. The outer edges are blue, while the inner two-thirds are yellowish with a bright, central core. Dark, dusty filamentary clouds wrap around the outer half of the galaxy’s disk. At 10 o'clock, a smaller dwarf elliptical galaxy forms a fuzzy, yellow blob. Hubble's sharp vision distinguishes about 200 million stars within the image. The background of space is black. There are what appears to be steps toward the bottom, mainly toward the middle, which indicates where no data were taken.

  2. Hubble Survey Unlocks Clues to Star Birth in Neighboring Galaxy

    September 03, 2015Release ID: 2015-18 Missions: Hubble

    All stars are not created equal. They can vary in mass by over a factor of 1,000. Our sun is classified as a diminutive yellow dwarf. What's more, stars are not born in isolation, but inside giant molecular clouds of...

  4. Hubble Zooms in on Double Nucleus in Andromeda Galaxy

    January 11, 2012Release ID: 2012-04 Missions: Hubble

    A new Hubble Space Telescope image centers on the 100-million-solar-mass black hole at the hub of the neighboring spiral galaxy M31, or the Andromeda galaxy, one of the few galaxies outside the Milky Way visible to the...

  5. Rare Ultra-blue Stars Found in Neighboring Galaxy's Hub

    January 11, 2012Release ID: 2012-03 Missions: Hubble

    Peering deep inside the hub of the neighboring Andromeda galaxy, NASA's Hubble Space Telescope has uncovered a large, rare population of hot, bright stars.

    At left is a view of the entire Andromeda galaxy. On the right are two images that show sections of the galaxy.
