 Here we have the Tadpole Galaxy. Its distorted shape was caused by a small interloper, a very blue, compact galaxy. You'll see it in the upper left corner of the more massive Tadpole Galaxy. Seen shining through the Tadpole's disk, the tiny intruder is likely a hit-and-run galaxy that is now leaving the scene of the accident. Some gravitational forces from the interaction created the long tail of debris, consisting of stars and gas that stretch out more than 280,000 light-years. The other interesting thing here is that most of the stars in the background are galaxies. There are 6,000 galaxies behind the Tadpole, moving very deep into space.
