Nothing at recorded position, but 10 arcmins to the west is a galaxy apparently identical to Muller's object, so it appears that object (NGC 2979, which see for pictures and physical discussion) is the one actually observed by Muller, and its position was simply misrecorded.

In a cluster of galaxies. Possibly identical to NGC 3046, which was recorded by Herschel on the same night, but does not appear to exist. Based on recessional velocity of 2550 km/sec, about 115 million light years away. Given that and apparent size of 2.1 by 1.9 arcmins, about 70 thousand light years across.

Based on recessional velocity of 1115 km/sec, nearly edge-on spiral galaxy NGC 3079 is about 50 million light years away, in reasonable agreement with redshift-independent distance estimates of 55 to 65 million light years. Given that and its apparent size of 7.9 by 1.5 arcmin, it is about 140 thousand light years across. The galaxy is undergoing an episode of unusually active star formation (a starburst), which is responsible for its classification as a Seyfert galaxy (type Sy2), and for a 3000 light year wide bubble of hot gas (with temperatures of up to ten million Kelvins) which is being blown out of its core. It is thought that this is a recurrent phenomenon, occurring perhaps every ten million years or so. The bubble we see now was probably created about a million years ago; but over time it will slow, fall back onto the galaxy, and as it does, compress other clouds of gas and dust to form a new starburst, repeating the phenomenon.
