Chandra Deep Field-South:
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.
