Description

The Leo Triplet, also called the M66 group, is a small group of spiral galaxies in the constellation Leo. The Leo Triplet is composed of two Messier objects, M65(top) and M66(bottom), as well as NGC 3628(left), which is also called the Hamburger galaxy due to its shape. All three are large spiral galaxies but tend to look different because their galactic disks are tilted at different angles to our line of sight. NGC 3628, is temptingly seen edge-on, with obscuring dust lanes cutting across its puffy galactic plane. The disks of M66 and M65 are both inclined enough to show off their spiral structure. Gravitational interactions between galaxies in the group have left telltale signs, including the 300,000 light-years long tidal tail and warped, inflated disk of NGC 3628 and the drawn-out spiral arms of M66. The three large spiral galaxies can be seen in a single field of view that covers over half a million light-years at a distance of 35 million light-years from Earth.
