Holmberg II is a irregular dwarf galaxy in the constellation Ursa Major. Its apparent magnitude is 11,1m and it is 11 million light years away from Earth. The galaxy is dominated by huge glowing gas bubbles, which are regions of star formation.
Holmberg II also hosts an ultraluminous X-ray source. One hypothesis suggests that is caused by an intermediate mass black hole that is pulling surrounding material.
Holmberg II was discovered by Erik Bertil Holmberg.
Holmberg II dominantly consists of huge bubbles of glowing gas, which are ongoing Star Formation sites.
