NGC 1592 is an irregular galaxy in the constellation Eridanus. It is about 20,000 light-years across. It has not been studied in detail, as it is at 27 degrees south, making it not visible below 63 degrees north in a flat area, and about 50 degrees north in a hilly area. It was discovered in 1835 by John Herschel.[2]

2014 observations[]

Until 2014, not much was known about the galaxy, other than the fact it was irregular. In early 2014, the galaxy was observed with a 2-foot telescope at the SARA remote observatory in Chile, revealing the galaxy in higher resolution. It appears the galaxy is in the process of forming stars at a high rate - primarily in the red areas in the image. Additionally, the galaxy has several small clumps of stars, implying an ongoing merger.[3]

Companions[]

NGC 1592 appears to have a companion, 2MFGC (2MASS Flat Galaxy Catalog) 3572, at 40 million light years away, assuming similar velocity with NGC 1592. they are separated by about 750,000 ±200,000 light years.[1]
