September deep sky images
Discover the depths of September’s deep sky with these superb images taken by two photographers and associates of EarthSky.
The Cygnus Loop
The Cygnus Loop is a big supernova remnant stretching from the constellation Cygnus the Swan into neighboring Vulpecula the Fox. Parts of the Cygnus Loop are additionally referred to as the Veil Nebula. The Cygnus Loop lies roughly 2,600 light-years from Earth. The intense tendrils and dusty filaments span 130 light-years in diameter, stretching three degrees throughout. A span of three levels would appear to be the width of six full moons on the dome of our sky. The nebula is about 21,000 years previous. As but, scientists have been unable to seek out the stellar remnant that brought about the supernova explosion.
Bode’s Galaxy, or M81 (Messier 81), lies in Ursa Main, to the higher proper of the Huge Dipper’s Bowl on September evenings. This majestic face-on spiral galaxy is shut sufficient to Polaris, the North Star, that you may technically seek out this deep-sky object on any evening of the 12 months from northern latitudes. Bode’s Galaxy shines at magnitude 6.9, making it an honest goal for binoculars. If you happen to exit galaxy attempting to find M81, you’ll be rewarded with a bonus galaxy close by, M82, an edge-on spiral shining at magnitude 8.4.
