This image was created by putting together multiple exposures from Chandra’s Advanced CCD Imaging Spectrometer for a cumulative exposure time of over one-million seconds. The multiwavelength observations of this region were carried out by a team led by Riccardo Giacconi in collaboration with scientists from the Very Large Telescope and the Paranal Observatory, both in Chile. Through the course of these investigations, the X-ray background was determined to originate from the central supermassive black holes of distant galaxies. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/chandra-deep-field/chandra-deep-field.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
