UGC 8320 is a dwarf irregular galaxy located in the constellation Canes Venatici. The galaxy measures approximately 4 × 1.5 kiloparsecs (13000 × 4900 lightyears) and has a large number of H II regions scattered across most of the observable face. Nearly all of the resolvable stars above magnitude 19.5 are blue giants of class O or B and the entire galaxy has a distinct blue appearance when viewed in visible light suggesting that it is in a state of vigorous star formation.
