Distant galaxies form a dramatic backdrop for disrupted spiral galaxy Arp 188, the Tadpole Galaxy. The cosmic tadpole is a 420 million light-years distant toward the northern constellation Draco. Its tail is about 280 thousand light-years long and features massive, bright blue star clusters. The intruder galaxy itself, estimated to lie about 300 thousand light-years behind the Tadpole, can be seen through foreground spiral arms at the upper left.
