Image Description and Details :

This is an image of NGC 6946, also known as the Fireworks Galaxy. It is a face-on intermediate spiral galaxy about 25 million light years away near the boundary of the constellations of Cepheus and Cygnus. It spans about 40,000 light years in diameter, which is about one third the size of the Milky Way. It is classified as a starburst galaxy which means there is a lot of star forming regions as can be seen in the magenta regions in the image.
