NGC 6946 Fireworks Galaxy
This spiral galaxy lies on the borders of the constellations of Cygnus and Cepheus. It is around 18 million lightyears distant and approximately 50,000 lightyears in diameter.
It is so named because of the unusually high rate of supernovae (exploding massive stars). Considerable dimming of its brightness occurs because it lies close to the plane of our galaxy.
This image is the result of one hour of remote imaging from a telescope in Spain.
