Deep Field in Canes Venatici:
Chandra Resolves Cosmic X-Ray Glow and Finds Mysterious New Sources
Chandra Image of Deep Field in
Canes Venatici. This Chandra X-ray Observatory
image of a 27.7 hour observation of a region in the
direction of the constellation Canes Venatici, close to
the Big Dipper, shows about 3 dozen X-ray sources. Some
of the sources were too faint to be seen by optical
telescopes such as the Hubble Space Telescope and the
Keck 10 meter telescope in Hawaii. This new class of
sources may represent some of the most distant objects
ever detected. If this sample of the sky is typical,
tens of millions of such sources must exist.
