About this Image

The distorted dusty galaxy NGC 3628 is a member of the famous Leo Triplet.
Lying at a distance of some 35 million light years, it also is probably physically related to the M 96 group.

A conspicuous band of dark dust clouds form a broad equatorial band, which obscures the galaxy's bright central region, and hides most of the bright young stars in its spiral arms. The dust band, or belt, is obviously distorted and deformed in the outer regions of the galaxy. The reason for this deformation is evidently the gravitational interaction with its two bright neighbors, M 65 and M 66.
