Description

NGC 3628 is a mag 10.3 unbarred spiral galaxy in Leo, part of the triplet with M65 and M66. It is estimated at 35 million light years distance. It was discovered by William Herschel in 1784. It has an approximately 300,000 light-years long tidal tail. The gravitional pull of the neighboring galaxies has most likely tipped the plane of NGC 3628 and made its central dust lane "wobbled" in appearence. Spectroscopic analysis of the stars and gas in the disk reveal interesting motion. The stars orbit the galaxy in the opposite direction of the gas. It is conjectured that galactic mergers have created this phenomena. Note the dim dwarf satellite galaxy beneath the main galaxy.
