The Leo Triplet
M 65, M66, NGC 3628
The Leo Triplet (also known as the M66 Group) is a small group of galaxies about 35 million light-years away in the constellation Leo. This galaxy group consists of the spiral galaxies M65, M66, and NGC 3628.

NGC 3628 is an active spiral galaxy with extended star creation areas and has a diameter of about 145,000 light years. The object is a so-called edge-on-galaxy, and also called "hamburger" or "sandwich galaxy". The spiral arms appear only as dark dusty clouds, illuminated by the bright center of the galaxy.

M 65 and M 66 show their spiral arms to us. The gravitational forces between the galaxies of the group are visible at the distorted slice of NGC 3628 and the extended spiral arms of M66.
