This false color image is an enlarge- ment of the visible light at the center of NGC 3310. The brightest features are rendered in red. Even the galaxy’s center is asymmetrical, with light from the upper spiral arm appearing much more clearly than that from the lower one. The wide horizontal strip at the lower left of the nucleus is really the upper spiral arm, wrapping to the galaxy’s center. The red spot above the strip lies at the very center of the nucleus. The nucleus, as this image indicates, is off-center (probably the result of NGC 3310’s having merged with a smaller galaxy). As the two galaxies joined and settled, redistribution of mass may have knocked the nucleus to one side.
