This Hubble image displays a pair of sprial galaxies with swirling arms. The binary glalactic system is located in the constellation of Draco, the Dragon, about 350 million light-years away. Although not found in the "head" area of Draco, these appear as eyes looking back on our own galaxy. Astronomers study glaxy pairs like this to determine the geometry of the universe, which sheds light on dark energy - which isn't just a SyFi term anymore.
