File:Chandra image of Sgr A.jpg
Summary
This <a href="//commons.wikimedia.org/wiki/Category:Chandra_X-ray_Observatory" title="Category:Chandra X-ray Observatory">Chandra</a> image of Sgr A* and the surrounding region is based on data from a series of observations lasting a total of about one million seconds, or almost two weeks. Such a deep observation has given scientists an unprecedented view of the <a href="//commons.wikimedia.org/wiki/Category:Supernova_remnants" title="Category:Supernova remnants">supernova remnant</a> near Sgr A* (known as Sgr A East) and the lobes of hot gas extending for a dozen light years on either side of the <a href="//commons.wikimedia.org/wiki/Black_hole" title="Black hole">black hole</a>. These lobes provide evidence for powerful eruptions occurring several times over the last ten thousand years. The image also contains several mysterious <a href="//commons.wikimedia.org/wiki/X-ray" title="X-ray">X-ray</a> filaments, some of which may be huge magnetic structures interacting with streams of energetic <a href="//commons.wikimedia.org/wiki/Category:Electron" title="Category:Electron">electrons</a> produced by rapidly spinning <a href="//commons.wikimedia.org/w/index.php?title=Neutron_star&action=edit&redlink=1" class="new" title="Neutron star (page does not exist)">neutron stars</a>. Such features are known as pulsar wind nebulas.
