A supernova remnant in the constellation Cygnus, located at a distance of approximately 1,500 light-years. The image is a detail from a much larger nebular region formed by a supernova explosion. The full remnant has a diameter of approximately 50 light-years and an apparent size of about three degrees on the sky (roughly six full Moons placed side by side).
This photograph shows a region about one degree across, corresponding to a true physical size of approximately 17 light-years. The massive star exploded as a supernova an estimated 7,000 years ago, leaving behind a network of faint, glowing gas filaments. Captured from Oulu in 2014 using a 25 cm reflector telescope, with a total exposure time of approximately 26 hours.
