Description

NGC7753-7752 is an interacting galaxy pair between 220-270 Million Light-Years distant toward the Constellation Pegasus. These galaxies belong to a class of interacting galaxies referred to as the M51-type. The smaller galaxy will eventually merge with the larger one, and it would appear that the smaller, highly active galaxy core is pullin away outer arm gas and dust from the larger galaxy. IC4526, also a faint galaxy near the NGC7753-52 pair, is approximately 600 Million Light-Years distant. NGC7753 is a barred spiral galaxy with a small core, but is a very large galaxy. In 2006, a supernova was observed in NGC7753. NGC7752 is an irregular galaxy with 3 major h-alpha areas and intense star formation. There is also a large amount of Integrated Flux Nebular material in the background.
