Astronomers have seen a distant galaxy that blasts away material with two trillion times the energy the sun emits — the biggest such eruption ever seen. That ejection of matter could answer an important question about the universe: why are the black holes in the centers of galaxies so light?

Computer models of the early universe usually produce a virtual cosmos that looks like ours except for one thing. The ratio of the mass of black holes in galaxy centers to the rest of the matter in galaxies is larger in the simulations than in the real universe.

A supermassive black hole discovered by University of Texas researchers ranks among the largest ever observed.

The enormous black hole is located in NGC 1277, a small, lenticular galaxy 250 million light years from Earth in the constellation Perseus, Space.com reports.

The black hole’s event horizon — the “point of no return” within which nothing can escape — has a diameter 11 times greater than Neptune’s orbit around the Sun, according to a written statement issued by the university’s McDonald Observatory in Austin.
