          These are the most well-known smaller (non-supermassive) black holes in the constellation Ophiuchus. 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.

              * For southern latitudes, flip the season listed. For example, if a constellation is listed as best viewed in the summer in the month of July, in the southern hemisphere the constellation would be best viewed in the winter in January and would be upside-down.

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