Hubble Looks at Face-On Spiral Galaxy NGC 6946 | Astronomy – Sci-News.com

Astronomers using the NASA/ESA Hubble Space Telescope have captured an amazing new photo of the medium-sized, face-on spiral galaxy NGC 6946.

This Hubble image shows the spiral arms and various stellar environments of NGC 6946. The color image was made from separate exposures taken in the infrared region of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Three filters were used to sample various wavelengths.

NGC 6946 is located approximately 18 million light-years away, along the border of the northern constellations of Cepheus and Cygnus.

Also known as LEDA 65001, UGC 11597 and APG 29, the galaxy has a diameter of 70,000 light-years.

NGC 6946 was discovered on September 9, 1798 by the German-born British astronomer William Herschel.

It is a member of the NGC 6946 group, which also includes several spiral and dwarf irregular galaxies.

“We are able to marvel at NGC 6946 as it is a face-on galaxy, which means that we see the galaxy facing us, rather than seeing it from the side,” Hubble astronomers said.

“This galaxy is further classified as an intermediate spiral galaxy and as a starburst galaxy.”

“The former means the structure of NGC 6946 sits between a full spiral and a barred spiral galaxy, with only a slight bar in its center, and the latter means it has an exceptionally high rate of star formation.”

“In the last century alone, NGC 6946 has experienced 10 observed supernovae, earning its nickname as the Fireworks Galaxy,” they added.

“In comparison, our Milky Way averages just 1-2 supernova events per century.”
