NGC 7603 is a spiral Seyfert galaxy in the constellation Pisces.[1] It is listed (as Arp 92) in the Atlas of Peculiar Galaxies.[4] It is interacting with the smaller elliptical galaxy PGC 71041 nearby.[1]
This galaxy pair has long been a cornerstone for those who are critical of the view that the universe is expanding, and advocates for non-standard cosmology such as Halton Arp, Fred Hoyle, and others.[5][6] This is due to the position of two quasars, one at each edge of the filament connecting the two galaxies, with much more redshift than either galaxy.
