A close-in view of the center of galaxy M82. Bright, bluish light radiating from the center is due to stars actively forming there. A thick lane of gas, black in the center and red around the edges, crosses the center and blocks much of the light. Thinner strands and clumps of reddish dust cover much of the rest of the view.

An artist's concept of a supermassive black hole, a surrounding disk of material falling towards the black hole and a jet containing particles moving away at close to the speed of light. This black hole represents a recently-discovered quasar powered by a black hole. New Chandra observations indicate that the black hole is growing at a rate that exceeds the usual limit for black holes, called the Eddington Limit. Credit: NASA/CXC/SAO/M. Weiss

$Gaseous yellow-orange filaments look like a rose seen from the side and tilted slightly from upper left to lower right, slightly higher than the center of the frame. Extending from the rose to upper left and lower right are gaseous outflows that appear as red lobes that have an overall shape of tall, narrow triangles with rounded tips. Each red triangle is made up of wavy, irregular lines. Dozens of stars are scattered across the field. One particularly bright white star with eight diffraction spikes is located at the top of the yellow rose. Another bright blue star with even more prominent diffraction spikes is to its lower left. The background of space is black.$
