NGC3628
NGC3628, sometimes referred to as the Hamburger Galaxy, is the lesser known and least bright, although the largest, of the Leo Triplet. Due to the gravitational influence amoung the three, including M65 and M66, massive numbers of giant blue stars light up the contorted arms of NGC3628. It is considered a starburst/low level AGN, and has extensive outgassing of neutral hydrogen. Some of this can be seen in the image. There is a broad and obscuring band of dark dust slicing through the plane of this edge-on galaxy, and the dust lanes are bowed a the ends, again due to heavy warping of the galaxy arms under gravitational influence.
