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

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

Near the center of these images lies the pulsar B1509-58, a rapidly spinning neutron star that is only about 12 miles in diameter. This tiny object is responsible for producing an intricate nebula (called MSH 15-52) that spans over 150 light-years, or about 900 trillion miles. The nebula, which is produced by energetic particles, resembles a human hand with a palm and extended fingers pointing to the upper right in a view from NASA's Chandra X-ray Observatory. Radio data from the Australia Telescope Compact Array (ATCA) provides new information about this exploded star and its environment. This image also contains optical data of hydrogen gas. The bright red and gold areas near the top of the image show the remains of the supernova that formed the pulsar.

A colorful nebula. The image’s top-left is filled with layers of fluffy pink and greenish clouds. Long strands of green clouds stretch out from here; a faint layer of translucent blue dust combines with them to create a three-dimensional scene. A sparse network of dark dust clouds in the foreground adds reddish-black patches atop the nebula. Blue-white and orange stars, from our galaxy and beyond, are spread throughout the clouds.
