Researchers used Chandra X-Ray Observatory to identify a powerful galactic blast produced by a giant black hole about 26 million light years from Earth. The black hole is the nearest supermassive black hole to Earth that is currently undergoing such violent outbursts. Messier51 system of galaxies contains a large spiral galaxy, NGC5194, colliding with a smaller companion galaxy, NGC5195.

“Just as powerful storms here on Earth impact their environments, so too do the ones we see out in space,” Schlegel said. “This black hole is blasting hot gas and particles into its surroundings that must play an important role in the evolution of the galaxy...

NuSTAR finds Cosmic Clumpy Doughnut around Black Hole

The most massive black holes in the universe are often encircled by thick, doughnut-shaped disks of gas and dust. This deep-space doughnut material ultimately feeds and nourishes the growing black holes tucked inside. Until recently, telescopes weren’t able to penetrate some of these doughnuts,ie tori.

“Originally, we thought that some black holes were hidden behind walls or screens of material that could not be seen through,” said Andrea Marinucci of the Roma Tre University in Italy...
