Galactic Center

Released on Monday: the center of our Milky Way Galaxy, as you’ve never seen it before (via NASA.) At bottom is a crop I made, showing more detail. This image release is part of Chandra’s 10th anniversary celebration.
A dramatic new vista of the center of the Milky Way galaxy from NASA’s Chandra X-ray Observatory exposes new levels of the complexity and intrigue in the Galactic center. The mosaic of 88 Chandra pointings represents a freeze-frame of the spectacle of stellar evolution, from bright young stars to black holes, in a crowded, hostile environment dominated by a central, supermassive black hole.
Permeating the region is a diffuse haze of X-ray light from gas that has been heated to millions of degrees by winds from massive young stars — which appear to form more frequently here than elsewhere in the Galaxy — explosions of dying stars, and outflows powered by the supermassive black hole — known as Sagittarius A* (Sgr A*). Data from Chandra and other X-ray telescopes suggest that giant X-ray flares from this black hole occurred about 50 and about 300 years earlier.

A strange image from the Chandra X-Ray Observatory, taken during the 100 Hours of Astronomy.
A small, dense object only twelve miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years. At the center of this image made by NASA’s Chandra X-ray Observatory is a very young and powerful pulsar, known as PSR B1509-58, or B1509 for short. The pulsar is a rapidly spinning neutron star which is spewing energy out into the space around it to create complex and intriguing structures, including one that resembles a large cosmic hand. In this image, the lowest energy X-rays that Chandra detects are colored red, the medium range is green, and the most energetic ones are blue. Astronomers think that B1509 is about 1700 years old as measured in Earth’s time-frame (referring to when events are observable at Earth) and is located about 17,000 light years away.
