NGC 6946 and NGC 6939

Face-on spiral galaxy NGC 6946 and commence star cluster NGC 6939 part this cosmic snapshot, easy with over 68 hours of image data captured with a puny telescope on planet Earth. The sphere of look spans spans about 1 diploma or 2 fleshy moons on the sky toward the northern constellation Cepheus. Viewed through faint interstellar grime couds near the plane of our Milky Approach galaxy, the stars of commence cluster NGC 6939 are 5,600 gentle-years within the gap, near bottom unbiased appropriate within the frame. Face-on spiral galaxy NGC 6946 is at top left, but lies some 22 million gentle-years away. Within the final 100 years, 10 supernovae had been present in NGC 6946, the most up-to-date one viewed in 2017. By comparability, the moderate payment of supernovae in our Milky Approach is set 1 every 100 years or so. Clearly, NGC 6946 will most certainly be identified as The Fireworks galaxy.
