NGC3395/3396

Image of NGC3395 and NGC3396 region in Leo Minor taken on February 14th 2020 from my Creedmoor site. NGC 3395 and NGC 3396, are a pair of closely interacting galaxies that appear to be in contract. Both are in the IRAS catalog of infrared sources, and this indicates massive star formation. However, neither galaxy is a particularly bright infrared object, and thus they have probably not actually collided.One current theory would suggest that these two are in the process of merging into a single elliptical galaxy. Some astronomers predict that this is the fate that awaits the Milky Way and spiral galaxy M-31 in about 5 billion years.This pair is included in Arp’s catalog of unusual galaxies as ARP 270. Using the red shift data from the “NASA Extra-galactic Data Base(NED)”, and a Hubble Constant of 62 Km per sec., per Megaparsec, one can calculate a rough distance and size for NGC 3395 as: Distance = 85 million light years; Diameter = 52,200 light years. NGC 3396 has the same red shift, which shows that both galaxies are at nearly the same distance.
