The Chandra Deep Field South (CDFS or CDF-S) is an
X-ray image of a small region of the sky
(within constellation Fornax) taken over a very
long exposure (on the order of 80 days) with the Chandra X-ray Observatory (CXO).
The image reveals many distant X-ray sources,
which suggest Black Holes, i.e., Active Galactic Nuclei.
