This object, also known as NGC 7678, is a face-on spiral galaxy located 150 million light years away in the constellation of Pegasus at a declination of +22 degrees. This galaxy spans 2 arc-minutes in our apparent view, which corresponds to a diameter of 90,000 light years.
In his
Arp catalog, Dr. Arp classified this object into the category of Spiral Galaxies with One Heavy Arm.
This is an active galaxy with a bright nucleus and a fascinating structure and color. The 2 arm grand design spiral shape has an additional star stream running down the left side of the galaxy. Many star clusters are seen, especially along the lower arm (the “heavy arm” of Arp’s classification). Something is disturbing this galaxy but there are no candidates in sight. It is perplexing to me that the disturbance source is not visible for so many disturbed galaxies.
One interesting addition to my image is the recent supernova SN 2021qvr. Discovered on June 22 of this year, about 1 month ago at magnitude 15, the supernova is currently at magnitude 16.
