Many people find the Andromeda galaxy from the two streams of stars extending from the Great Square (they are the constellation Andromeda). Or they find the galaxy via the constellation Cassiopeia. This photo via EarthSky Facebook friend Cattleya Flores Viray.
Our findings are statistically consistent with a head-on collision between the Andromeda galaxy and our Milky Way galaxy, said Roeland van der Marel of the Space Telescope Science Institute (STScI) in Baltimore. The solution came through painstaking NASA Hubble Space Telescope measurements of the motion of Andromeda, which also is known as M31. The galaxy is now 2.5 million light-years away, but it is inexorably falling toward the Milky Way under the mutual pull of gravity between the two galaxies and the invisible dark matter that surrounds them both.
