Scientists using NASA’s Hubble Space Telescope have discovered that the immense halo of gas enveloping the Andromeda Galaxy, our nearest massive galactic neighbour, is about six times larger and 1,000 times more massive than previously measured.
Using NASA’s Hubble Space Telescope, astronomers have captured for the first time snapshots of fledgling white dwarf stars beginning their slow-paced, 40-million-year migration from the crowded centre of giant globular cluster 47 Tucanae to the less populated suburbs.
ESO’s VISTA survey telescope has spied a horde of previously hidden massive galaxies that existed when the universe was in its infancy. By discovering and studying more of these galaxies than ever before, astronomers have, for the first time, found out exactly when such monster galaxies first appeared.
