Messier 66 (also known as NGC 3627) is an intermediate spiral galaxy about 36 million light-years away in the constellation Leo. It was discovered by Charles Messier in 1780. M66 is about 95 thousand light-years across with striking dust lanes and bright star clusters along sweeping spiral arms. M66 is part of the famous Leo Triplet, a small group of galaxies that also includes M65 and NGC 3628.
Gravitational interaction from its past encounter with neighboring NGC 3628 has resulted in:
An extremely high central mass concentration;A high molecular to atomic mass ratio;A resolved noncorotating clump of H I material apparently removed from one of the spiral arms. This third result shows up visually as an extremely prominent and unusual spiral arm and dust lane structures as originally noted in the Atlas of Peculiar Galaxies.[1]
