11/09/2010 NGC 4452: An Extremely Thin Galaxy
At first I thought this was a picture of a frisbee in space, but it turned out to be a view of galaxy NGC 4452 from the plane of the galaxy itself, which is even cooler! It is located in the Virgo Galaxy Cluster, which is the closest to the to the Milky Way. It is a lenticular galaxy, which is a disc galaxy that's used up most of its interstellar matter. It is roughly as thick as the Milky Way. The picture is almost perfectly edge-on with this galaxy. This would probably greatly surprise the average person who doesn't know much about astronomy, because they think it's all just stars and bright spots of light, whereas there are actually lots of interesting shapes like this line segment or molecular dust clouds.
