NASA’s Hubble Space Telescope spots double quasars in merging galaxies


(CNN) - The Hubble Space Telescope has captured a rare cosmic spectacle.

Two pairs of intense beacons of light called quasars in separate galaxies appear to be merging.

Supermassive black holes are powering the quasars, which are relatively so close to each other that Earth-based telescopes see them as one object.

The quasars are circling in an ever-tightening orbit; and within a few million years, they'll smash into each other. This will create a single, even larger black hole.

While the researchers stand by their findings, they admit this sighting could be an illusion created when gravity forces light to bend.
