The Fireworks Galaxy is a beautiful spiral galaxy on the border of constellations Cepheus and Cygnus. It is estimated to be at a distance of 22 million light years away from Earth. The word "fireworks" is used as a reference to supernova activity; to date, nine supernovae have been observed in the galaxy. Also visible in this image, at upper left, is open cluster NGC6939.
