A small constellation of the northern sky in a relatively barren region below the rim of the Big Dipper, between the Shepherd and the constellation Berenice's Hair. It is partly circumpolar in our latitudes, being highest in the sky during the lengthening evenings of the spring season. The Hunting Dogs are located near the galactic pole, so we see this constellation perpendicular to the Milky Way from us and therefore see far beyond our Galaxy. It should come as no surprise that the Hunting Dogs are very rich in extragalactic objects. Virtually all of the galaxies in the constellation visible in our amateur telescopes are part of one massive supercluster of galaxies, Virgo, the center of which is 60 million light-years away from us and is projected in the sky at the boundary between the constellations Virgo and Berenice's Hair. Our Local Group, which lies on the edge of this supercluster, is probably part of it. There are three groups of galaxies in the Hunting Dogs. The closest, about 20 million light-years away, is the Canes Venatici I group, which includes galaxies such as M94, M106, NGC 4214, NGC 4244, NGC 4395, and NGC 4449. Another group, Canes Venatici II, 35-40 million light-years away, includes M63, NGC 4111, NGC 4242, NGC 4490, NGC 4618, NGC 4631, and NGC 4800. The third group, Ursa Major I, 70-80 million years away, includes NGC 4145, NGC 4151, NGC 4217, and NGC 4369.
