Aurora Borealis as seen from the International Space Station

The Tadpole Galaxy (also known as UGC 10214 or Arp 188) is a disrupted barred spiral galaxy located about 420 million light-years away toward the northern constellation Draco. Its most dramatic features are an incredibly long trail of stars and massive, bright blue star clusters, reflecting the essence of our dynamic, restless and violent Universe. - Credit: NASA, Hubble, Mehdi Bozzo-Rey
