Notes: |
Arp 188, the Tadpole Galaxy, is a disrupted barred spiral galaxy located 420
million light-years from Earth in the northern constellation Draco. Its
eye-catching tail is about 280 thousand light-years long and features
massive, bright blue star clusters. The tail is a result of a merger with a
smaller galaxy that is believed to have occurred about 100 million years
ago. In the upper right corner of the image you can find a distant galaxy cluster with a redshift of z=0.251, which corresponds to a light travel time of 3 billion years. |
