M 66 is a very beautiful spiral galaxy in Leo. Together with M65 and NGC 3628 they form the so called Leo Triplet. M 66 is about 35 million light years away and shows deformed spiral arms, most probably due to gravitational encounters with the other members of the Triplet, as well as very conspicuous blue (young stars, a signal for high star-birth rate, probably due to its encounters…) and red (hydrogen -Hα- gas emission areas). This galaxy appears twice in Halton Arp’s Catalog of Peculiar Galaxies, as number 16 (alone) and 317 (the complete Triplet).
