Scientists have found four enormous cavities, or bubbles, at the center of a galaxy cluster using NASA's Chandra X-ray Observatory.

This unusual set of features may have been caused by eruptions from two supermassive black holes closely orbiting each other.

A new Chandra study of the galaxy cluster known as RBS 797, located about 3.9 billion light-years from Earth, uncovered two separate pairs of cavities extending away from the center of the cluster.

These types of cavities have been seen before in other galaxy clusters.

Scientists think they are the result of eruptions from regions near a supermassive black hole in the middle of the massive central galaxy.

As matter flies away from the black hole as jets in opposing directions, it blows cavities in the hot gas.

The revelation in RBS 797 is that there are two sets of jets directed perpendicular to each other.

Four giant cavities have been discovered in a galaxy cluster.

This quartet was found by NASA's Chandra X-ray Observatory.

Astronomers think two supermassive black holes blew these bubbles.

This number of cavities represents black hole behavior never seen before.
