Head on collision: Milky Way and Andromeda to merge … in a few billion years

Will our Milky Way Galaxy collide one day with its larger neighbor, the Andromeda Galaxy? Most likely, yes. Careful plotting of slight displacements of M31’s stars relative to background galaxies on recent Hubble Space Telescope  images indicate that the center of M31  could be  on a direct collision course with the center of our home […]

So close, and spanning some 260,000 light-years, it took 11 different image fields from the Galaxy Evolution Explorer (GALEX) satellite’s telescope to produce this gorgeous portrait of the spiral galaxy in ultraviolet light.

The Deep Field images were created by pointing the Hubble Space Telescope for several days at a tiny patch of apparently empty sky — “empty” sky that turned out to […]
