Chandra Deep Field
Credit: Riccardo Giacconi et al., JHU, AUI, NASA
Explanation: Officially the Chandra Deep Field - South, this picture represents the
deepest ever x-ray image of the Universe. One million seconds of accumulated exposure
time with the orbiting Chandra X-ray Observatory went in to its making. Concentrating on
a single, otherwise unremarkable patch of sky in the constellation Fornax, this x-ray image
corresponds to the visible light Hubble Deep Field - South released
