From Astronomy Picture of the Day; July 4, 2025:

NGC 6946 and NGC 6939 Alberto Pisabarro

Face-on spiral galaxy NGC 6946 and open star cluster NGC 6939 share this cosmic snapshot, composed with over 68 hours of image data captured with a small telescope on planet Earth. The field of view spans spans about 1 degree or 2 full moons on the sky toward the northern constellation Cepheus. Seen through faint interstellar dust clouds near the plane of our Milky Way galaxy, the stars of open cluster NGC 6939 are 5,600 light-years in the distance, near bottom right in the frame. Face-on spiral galaxy NGC 6946 is at top left, but lies some 22 million light-years away. In the last 100 years, 10 supernovae have been discovered in NGC 6946, the latest one seen in 2017. By comparison, the average rate of supernovae in our Milky Way is about 1 every 100 years or so. Of course, NGC 6946 is also known as The Fireworks Galaxy.

FIREWORKS GALAXY The Fireworks Galaxy, also known as NGC 6946, Arp 29, or Caldwell 12, is located 10 million light years away, on the border between the constellations of Cepheus and Cygnus. It is nearly 40,000 light years across and was discovered by William Herschel on September 9, 1798.

On Earth we see NGC 6946, a SAB-type intermediate spiral galaxy, nearly face on. It is obscured by interstellar matter from the Milky Way galaxy, as it is quite close to the galactic plane. In this image, the colours of the galaxy indicate the type of stars. The old stars in the core are yellowish while the blue stars are young and in clusters; the red areas are star forming regions. The galaxy is bright in infrared and rich in gas and dust as it has a high star formation rate. A suggested explanation for this high rate is the recent accretion of many primordial low-mass neutral hydrogen clouds from the surrounding region. At least nine supernovae have been discovered within NGC6946 over the past 100 years; the average rate for supernovae in the Milky Way is about 1 per century. -TEL http://apod.nasa.gov/apod/ap110101.html; http://www.astropix.com/ Image Credit & Copyright: Adam Block, Mt.

NGC6946 (Fireworks Galaxy)

Cutting through the borders of the constellations of Cepheus and Cygnus, the Fireworks Galaxy is located 25.2 million light years from our own, making it a near neighbour. 

The image was taken colourising an x-ray image. Black Holes commonly emit X-Rays, and the supermassive one is clearly defined at the centre.
