The constellation of Coma Berenices can be found around a huge and faint open cluster of Mel. 111 in north east of Leo. The constellation refers to a story concerning the hair of Berenice, queen of ancient Egypt. She offered her own hair on the temple of altar to pray the triumph of her husband.
Around the border of Coma Berenices and Virgo coincides the North Pole of Galactic coordinates; so hardly includes the inner-galactic matter to obstruct the dimmed light from deep space. We can appreciate uncountable galaxies around the field on account of this. The constellation includes 8 Messier's objects and seven of those are galaxies around 10 to 50 millions light years away. Almost all of bright galaxies around the boundary on Virgo belong to the "Virgo galactic cluster" about 70 millions light years away. And it's known that a larger galactic cluster of "Coma cluster" about 300 millions light years away at around the northern region of the constellation. Those galactic clusters consist of some thousands of individual galaxies. And it's considered that the "Local group of galaxies" which includes our Galaxy, is pulled by their gigantic gravitation.
