In eastern region of a constellation of Lyra, this image shows you a tiny colliding galaxy pair of NGC6745. It's considered that the galaxy was originally a normal shaped spiral, and violently warped by a collision with a small opponent galaxy in just north, now it looks like a crescent shape. The Hubble Space Telescope (HST) has captured a detailed structure of the pair.
