A Greedy Black Hole Eats Through Two Giant Cosmic Spirals

Astronomers have discovered a supermassive black hole at the heart of the Circinus galaxy, feeding on two enormous spiral arms of gas.

This rare cosmic phenomenon was discovered by a team led by Wout Goesaert from Leiden University in the Netherlands, using data from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile.

The Circinus galaxy, located about 13 million light-years from Earth, was only discovered in 1977 and sits behind the Milky Way's disk.

The team's results provide a vivid look at how material flows toward black holes and will be published in Astronomy & Astrophysics.

This rare cosmic phenomenon shows how some of the universe’s hungriest objects gather their meals—and how surprisingly wasteful they can be.

Astronomers used data from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to make this discovery.
