  The Leo Trio is a group of galaxies in the constellation Leo, consisting of NGC 3628 (left), M65 (top right) and M66 (bottom right). These are also known as the M66 group and are close enough to each other that gravitational interactions are visible such as the inflated disk of NGC 3628 (also known as the Hamburger Galaxy) and the distorted arms of M66. The group's distance from earth is estimated to be 30 - 35 million light years. M65 and M66 were discovered by Pierre Méchain in March 1780 when they were also catalogued by Messier.
