The Hubble Space Telescope has captured an amazing view of a strange hybrid galaxy 400 million light-years away.
The galaxy, called UGC 12591, is odd because it's a cross between a typical lenticular and spiral galaxy. It is located in the westernmost reaches of the Pisces-Perseus Supercluster - a vast chain of galaxy clusters that extends across hundreds of millions of light-years. The galaxy is also a fast spinner, rotating at a mind-boggling 1.1 million mph (1.8 million km/h), according to a NASA description. [8 Galaxies With Really Weird Names]
"The galaxy itself is also extraordinary: it is incredibly massive," NASA officials wrote in an image description. The galaxy and its halo together contain several hundred billion times the mass of the sun; four times mass of the Milky Way."
Using the Hubble Space Telescope astronomers are beginning to understand the mass of UGC 12951, NASA officials added. Scientists are using data from Hubble to establish whether the monster galaxy formed and stretched over time, or if it was formed from two large galaxies colliding at some point in the distant past, they added.
The Pisces-Perseus Supercluster of galaxy clusters, which UGC 12951 calls home, is one of the largest known structures in the universe, NASA officials added.
