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	Chandra's extremely deep image provides a crucial view of one of the most intensively studied patches of the night sky, the Hubble Deep Field North. This area has been examined at all wavelengths, from radio through optical and now X-ray. About half the X-ray sources in this image are due to matter falling into supermassive black holes in the centers of active galaxies and quasars. Other sources include galaxies that are much like our own Milky Way galaxy, but several billion years younger. The X-rays are color coded with shades of red representing lower energies and blue representing the highest energies.
