Explanation: Close to the Great Bear (Ursa Major) and surrounded by the stars of the
Hunting Dogs (Canes Venatici), this celestial nebula was discovered in 1781 by the metric
French astronomer Pierre Mechain and later added to the catalog of his friend and colleague
Charles Messier as M106. Modern deep telescopic views reveal it to be an island universe -- a
spiral galaxy around 30 thousand light-year |
