In this image, two spiral galaxies collide, however they lie millions of light-years away, far beyond the cloud of blue and red stars near the merging spiral. This sprinkling of stars is actually an isolated, irregular dwarf galaxy named ESO 489-056. This galaxy floats 16 million light-years from Earth in the constellation of Canis Major (The Greater Dog). It contains a few billion red and blue stars — a very small number when compared to galaxies like the Milky Way, estimated to contain around 200 to 400 billion stars, or the Andromeda Galaxy, which contains one trillion.
