NASA has released an amazing new image showcasing the galaxy UGC 12591. The galaxy lies about 400 million light years away from us in the westernmost region of the Pisces–Perseus Supercluster, a long chain of galaxy clusters that stretches out for hundreds of light-years — one of the largest known structures in the cosmos.
The galaxy is incredibly massive. The galaxy and its halo together contain several hundred billion times the mass of the Sun; four times the mass of the Milky Way.
UGC 12591 is a hybrid galaxy, combining the characteristics of both lenticular and spiral galaxies. The galaxy’s massive spirals are rotating at extreme speeds, in excess of 1 million miles per hour.
