MCG-1-22-2, Mark Bowman

These two Galaxyies are called Lenticular Galaxies, meaning that they appear to be spiral galaxies only without the arms that flow out from the center. These galaxies tend to show up between a spiral galaxy and an elliptical galaxy. They generaly consist of a group of old stars which grouped together over time, smoothing out, creating almost no inner structure. A point which is driven home by the lack of blues stars, usualy the youngest stars in a group, which form inthe spiraling arms of Galaxies.

This image contains twin different galaxies; the biggest is MCG-1-22-2 with a linear size of 32 arc seconds, lies in the left side of the picture. The other which is the smaller of the two, 16 arc seconds, is located in the top right portion of the image. These galaxies are distinct in the picture because of their faint auras around them.
