The Chandra Deep Field South (CDF-S) is one of the deepest observations obtained with the X-ray Chandra satellite, which stared at the same path of the sky for 11 days. The final image is the result of the co-addition of 11 individual Chandra ACIS-I exposures obtained in 1999-2000, for a total of one million seconds (1 Msec). The project was lead by Riccardo Giacconi. The nominal aim point of the CDF-S is RA=3:32:28.0 , Dec=-27:48:30 (J2000), covering 0.11 square degree. After these observations, the CDF-S has become the center of one the most comprehensive multi-wavelength campaign ever carried out with ground-based and space observatories.
