Black Holes

A black hole is a location in space that possesses so much gravity, nothing can escape its pull, even light. Learn more about what black holes are and the latest news.

Evidence for the biggest explosion seen in the universe comes from a combination of X-ray data from NASA’s Chandra X-ray Observatory and Europe’s XMM-Newton space telescope, and the Murchison Widefield Array and Giant Metrewave Telescope, as shown here. The eruption is generated by a black hole located in the cluster's central galaxy, which has blasted out jets and carved a large cavity in the surrounding hot gas. Researchers estimate this explosion released five times more energy than the previous record holder and hundreds of thousands of times more than a typical galaxy cluster.

This Newfound Monster Black Hole Is Too Big for Theories to Handle

By Elizabeth Howell

Scientists recently found a black hole so big that current theory strains to prove it exists, a new study reports.

This composite image combines data from NASA's Chandra X-ray Observatory and the NSF's Karl Jansky Very Large Array (VLA). Chandra observed powerful X-rays (red) produced by hot gas circling around a black hole at the center of a galaxy located 9.9 billion light-years from Earth. The VLA was used to detect radio-wave emissions (blue) emitted by the jet of high-energy particles streaming from the black hole.
