NASA’s Hubble Space Telescope has captured hybrid galaxy UGC 12591’s spectacular size and structure in its latest detailed high-quality image.

UGC 12591 has the characteristics of both a lenticular and spiral galaxy. It is four times bigger than the Milky Way and its spirals rotate at speeds of over 1.1 million miles an hour.

Located 400 million light-years from Earth, UGC 12591 is part of one of the largest structures in the universe, the Perseus-Pisces Supercluster, which stretches for hundreds of lightyears, spanning 40 degrees of the winter sky in the northern hemisphere.
