This NASA/ESA Hubble Space Telescope image showcases the remarkable galaxy UGC 12591. Classified as an S0/Sa galaxy, UGC 12591 sits somewhere between a lenticular and a spiral. It lies just under 400 million light-years away from us in the westernmost region of the PiscesâPerseus Supercluster, a long chain of galaxy clusters that stretches out for hundreds of light-years â one of the largest known structures in the cosmos. The galaxy itself is also extraordinary: it 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. It also whirls round extremely quickly, rotating at speeds of up to 1.8 million kilometres per hour! Observations with Hubble are helping astronomers to understand the mass of UGC 1259, and to determine whether the galaxy simply formed and grew slowly over time, or whether it might have grown unusually massive by colliding and merging with another large galaxy at some point in its past.

The Hubble space telescope has captured a new image showcasing an incredibly massive galaxy located under 400 million light—years away from the Earth.

The galaxy UGC 12591 sits somewhere between a lenticular and a spiral, according to NASA.

It lies 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.

UGC 12591 itself is also extraordinary: it is incredibly massive, NASA said.

The galaxy and its halo together contain several hundred billion times the mass of the Sun; four times the mass of the Milky Way.

It also whirls round extremely quickly, rotating at speeds of up to 1.8 million kilometres per hour.
