NGC-6946 Spiral galaxy in Cepheus
NGC-6946 is a face-on intermediate spiral galaxy located in the constellation of Cepheus, near the Cepheus/Cygnus border. It lies 25 million light years from Earth and is 40,000 light years in diameter. It was discovered by Sir William Herschel in 1798. Because it lies close to the plane of our own Milky Way galaxy, NGC-6946 is heavily obscured by intervening interstellar dust and gas. NGC-6946 is undergoing intense star formation, and is classed as a Starburst Galaxy.
