APOD 2.3 Arp 188 and the Tadpole's Tail

http://apod.nasa.gov/apod/ap121108.html

This image, from the Hubble Legacy Archive, details an image of galaxy "Arp 188". Arp 188 is also known as the Tadpole. I can clearly see why it is known as the tadpole being that there is a long jet of gas being emitted from one side of the galaxy which gives it a 'tadpolesque' look. This galaxy is 420 million light years away from the the constellation Draco, which is actually pretty close despite the 'astronomical' numbers. The tail alone is 280 thousand light years long. The tadpole galaxy is filled with beautiful blue stars in the head and some in the tail. However, it is estimated that the tail of the galaxy will eventually split from the head and become a small satellite that will always hover near the head.
