The supermassive black hole at the center of the Milky Way galaxy devours a snack.

Sagittarrius A*, the Milky Way's supermassive black hole, emits an x-ray flare indicating the ingestion of some kind of galactic matter.

Asteroids might be a popular snack for supermassive black holes, but the exact nature of their diet has yet to be revealed.

The Milky Way, shown here as an artist's concept, is home to Sagittarius A*, a supermassive black hole at the galaxy's center.

NuSTAR is the only telescope capable of producing focused images of the highest-energy X-rays emitted by dying stars and hungry black holes.
