Metadata

This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.

Image title	This Chandra image of NGC 4636 shows symmetric arms, or arcs, of 10 million degree gas extending 25,000 light years into a cloud of hot gas that surrounds the galaxy. The length and shape of the arms, along with their temperature which is hotter than the surrounding gas cloud, suggest that they are the leading edge of a galaxy-sized shock wave that is racing outward from the center of the galaxy at 700 kilometers per second. The initial outburst is thought to have been triggered by gas falling into a central massive black hole.
