This as a high quality picture of the Andromeda Galaxy. This galaxy is the closest one to ours at an outstanding 2.5 million light years away.  When I saw this I said to my home-dawg, "yo bro, check this out!" then my boy was like "You should totes post this on your blog!" The deep shades of blue are caused by hot, massive, and young stars which were created when a smaller gallexy merged.
