Hubble Telescope Captures Galaxy

IAS Prelims 2023

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.

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.

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.
