The object is a compact blue dwarf
galaxy that is infused with newly formed clusters of stars. The bright, blue
stars that arise in these clusters help to give the galaxy an overall bluish
appearance that lasts for several million years until these fast-burning stars
explode as supernovae.
UGC 5497 is considered part of the M 81
group of galaxies, which is located about 12 million light-years away in the
constellation Ursa Major (The Great Bear). UGC 5497 turned up in a ground-based
telescope survey back in 2008 looking for new dwarf galaxy candidates
associated with Messier 81.
