The Tadpole Galaxy (or Arp 188) is currently suffering a strong interaction with another galaxy. Tidal forces have created a 280 000 light years long tail with massive star formations: there are many bright star clusters containing a huge quantity of young and hot blue stars. The galaxy is 420 million light years away from us in the constellation Draco. The intruder galaxy is estimated to be located about 300 000 light years behind Arp 188. Its foreground arms can be seen to the upper right. Part of the beauty of this image is the many background galaxies that you can discover on the full size version of this image.
