The Big Bear, Ursa Major, is the third largest constellation in the skies, seen at northern sky in evening of spring. The constellation has no first magnitude stars, but the Big Dipper that forms the bear's tail is a rough guide on the clarity of the evening's sky.
Though Ursa Major contains no bright celestial objects, it has plenty of galaxies in outer space.
