Chandra Deep Field South :
Deepest X-Rays Ever Reveal universe Teeming With Black Holes
Deepest X-Rays Ever Reveal universe Teeming With Black Holes
This one-million-second image, known as the "Chandra Deep Field-South" since it is located in the Southern Hemisphere constellation of Fornax, is the deepest X-ray exposure ever achieved. Most of the objects seen in the Chandra Deep Field-South are active galaxies and quasars powered by massive black holes. Also in this Chandra Deep Field-South image, for the first time in such deep exposures astronomers detect X-rays from many galaxies, groups, and clusters of galaxies. The intensities of the X-rays in this image are depicted, from lowest to highest energies, by red, yellow, and blue respectively.
Another early exciting discovery to emerge from the Chandra Deep Field-South is the detection of an extremely distant X-ray quasar shrouded in gas and dust. The discovery of this object, some twelve billion light years away, is key to understanding how dense clouds of gas form galaxies with massive black holes at their centers.

Visual Description:
The one-million second image of the Chandra Deep Field South is a representation of the vastness and complexity of space. The image showcases an array of active galaxies and black holes. The colors in the image are predominantly shades of black, gray, and white, with occasional flashes of blue, red, and green. The intensities of the X-rays in this image are depicted, from lowest to highest energies, by red, yellow, and blue respectively. The Chandra Deep Field-South is located in the Southern Hemisphere constellation of Fornax, and was the deepest X-ray exposure ever achieved at the time of observation.
