NGC 3628 is a member of the famous Leo Triplet, which also includes M65 and M66. Having been slightly too faint to fall under the gaze of Charles Messier, this peculiar edge-on spiral galaxy did not reveal itself until the famed English astronomer William Herschel trained his large reflector onto this part of the sky some years after Messier's survey. Lying at a distance of about 35 million light years from earth, this member of the Triplet rewards the observer with a spectacular equatorial dust lane of incredible detail and form. The outer reaches of this galaxy have a contorted or tortured appearance, that being the result of gravitational interaction from its nearby neighbors M 65 and M66. A host of smaller, fainter galaxies are sprinkled throughout the field of view, with two faint satellite galaxies of NGC 3628 located directly below the nucleus in the above image.
