M65 in Leo is an elegant spiral galaxy which is highly inclined to our line of sight, revealing a prominent and bright central bulge. Apart from the bulge, the other notable feature of M65 is its dust lane, which so obviously surrounds the galaxy but is only clearly seen where it hides a bright background. Elsewhere, dust is associated with bright, clumpy knots of star formation visible along the inner spiral arm. One arm of the galaxy seems slightly displaced, as though it had undergone some interaction with other massive galaxies. This is hardly surprising, since it is a member of a small group about 30 million light years away that includes M66 and NGC 3628.
