A Black Hole


A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope. The black hole at the center of galaxy M87 is outlined in the image by emission from hot gas swirling around it under the influence of the strong gravity near the event horizon.

M87


The halo of galaxy Messier 87The giant elliptical galaxy Messier 87 is surrounded by a huge halo. An increase in brightness in the top-right part of this halo and the motion of planetary nebulae in the galaxy are the last remaining signs of a medium-sized galaxy that collided with M87.

This wide field image also contains many other galaxies forming the Virgo Cluster, of which Messier 87 is the largest member. The two galaxies at the edge of the top right of the frame are nicknamed “the Eyes.”

Hot Gas Jet in M87


This video zooms in on a black-hole-powered jet of hot gas in the giant elliptical galaxy M87. The time-lapse movie shows hot plasma spiraling along magnetic field lines generated by the supermassive black hole over a 13-year period. It was assembled from images take by the Hubble Space Telescope.
