The Tadpole Galaxy is a disrupted barred spiral galaxy located 400 mly from Earth toward the northern constellation Draco. It's most dramatic features are a trail of stars about 280,000 lys long massive star clusters. It is thought that a more compact galaxy crossed in front of the Tadpole Galaxy was slung around behind the Tadpole by their mutual gravitational attraction.
The Sombrero Galaxy - 28 million light years from Earth - was voted best picture taken by the Hubble telescope. The dimensions of the galaxy, officially called M104, are as spectacular as its appearance
