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...

At the center of this amazing Hubble image is the elliptical galaxy NGC 3610. Surrounding the galaxy are a wealth of other galaxies of all shapes. There are spiral galaxies, galaxies with a bar in their central regions, distorted galaxies and elliptical galaxies, all visible in the background. In fact, almost every bright dot in this image is a galaxy — the few foreground stars are clearly distinguishable due to the diffraction spikes (lines radiating from bright light sources in reflecting telescope images) that overlay their images.
