Narrator (April Hobart, CXC): This image is what is known as the Chandra Deep Field South, a 4-million-second exposure made by NASA's Chandra X-ray Observatory. Located in the constellation of Fornax, this is the deepest X-ray image ever obtained of the sky. Most of the sources in this image contain rapidly growing supermassive black holes. Some of these black holes are seen to exist when the Universe is less than about 950 million years old.
