              Black Holes in Ursa Major

              These are the most well-known smaller (non-supermassive) black holes in the constellation Ursa Major. Although black holes cannot be seen directly, the smaller ones are at the center of some star clusters and supernova remnant nebulae, which can be seen. Supermassive black holes are at the center of most galaxies, such as Sagittarius A* at the center of our Milky Way galaxy. Also see all black holes.

                * Constellation shown for northen hemisphere skies. For the southern hemisphere, constellations appear rotated 180 degrees (upside-down and left-right reversed) from what is shown. Remember that seasons are reversed too - summer in northern latitudes is winter in southern latitudes.

                ** Circumpolar constellations are visible year-round in the hemisphere listed (and not at all in the opposite hemisphere).
