Lost Gallexy

The Lost Galaxy is leticular galaxy. A leticular galaxy is kind of like a spiral galaxy and a ecliptical galaxy but it is neither. The spiral arms are less visible than in a spiral galaxy and the space dust is located differently than in an elliptical galaxy. It is also located in the Virgo cluster.

The picture itself is kind of a mystery. There is an obvious glowing center and then the glow of it kind of makes a football and fades out into space. The galaxy almost looks like a ghost. It is so dim, and it looks like light stopped being produced and that all that it left is light that is still getting to earth, but where did the galaxy go? That is why it is called the Lost Galaxy. The angular size of this galaxy is 4.4 by 1.4 arcminutes. The Liner size of it is 70,862 by 21,904 light years.
