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.

Observations with Hubble are helping astronomers to understand the mass of UGC 12591, 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.

Another achievement of NASA is the completion of the James Webb Space telescope which the space agency completed after nearly two decades of building. James Webb Space Telescope is considered to be the successor to NASA’s 26-year-old Hubble Space Telescope.

NASA said the Webb telescope will be used to observe distant objects in the universe, provide images of the first galaxies formed and see unexplored planets around distant stars.
