The galaxy NGC 6946 is often the focus of astronomers’ attention. In the last century alone, 10 supernovae have been recorded in NGC 6946. The Hubble Space Telescope has captured a new image of the galaxy in impressive detail.
Nicknamed “Fireworks” or “Galaxy of Fireworks”, NGC 6946 is famous for its frequent supernovae. Let us recall that a supernova or a supernova explosion is a phenomenon during which a star sharply increases its brightness by 4 – 8 orders of magnitude, followed by relatively slow decay. For comparison, in our Milky Way galaxy, there are only 1-2 supernova events per century.
A new image from NASA/ESA’s Hubble Space Telescope shows the stars, spiral arms, and various stellar environments of NGC 6946 in phenomenal detail.
It is worth noting that NGC 694 is “facing us”; earthlings are not watching it from the side. That is why all the details of the “Galaxy of Fireworks” are available to us. In addition to the frequent death (flare-up) of stars in NGC 694, it is distinguished by an exceptionally high rate of star formation.
The galaxy is located at a distance of 25.2 million light-years from us, on the border of the northern constellations Cepheus and Cygnus.
The constellation Cygnus is easy to see in the northern hemisphere summer sky. This new Herschel Telescope view of the Cygnus X star-forming region highlights the chaotic networks of dust and gas that point to massive star formation sites.
