Spiral Galaxy NGC 3628 |

About This Photograph
At a distance of some 30 million light years in the constellation of Leo we find this fine example of a spiral galaxy viewed edge-on. The distinct lanes of dust and gas bisecting the body of the galaxy are the tell-tale clue that it has a spiral form. In fact, our own galaxy demonstrates such lanes, as can be seen clearly when the summer Milky Way is overhead and viewed from a dark location, away from city lights.
NGC 3628 is a member of a group of galaxies, and gravitational interaction with the other members has left this galaxy a bit disturbed. Note the warp of the disk and the flaring of the outer rim of the galaxy. There is also a faint tail of material above and to the left of the main galaxy, orphan stars thrown off into intergalactic space by a gravitational encounter.
