Chandra Deep Field South Animation

This video sequence pinpoints the seven X-ray sources [supermassive black holes] discovered in the southern field with the Chandra X-ray Observatory that cannot be seen in the Hubble view. The sequence begins with a view of the full Chandra field. Small boxes appear which pinpoint the black holes [the red and yellow blobs]. The video then zooms into the Chandra field to show close-ups of two black holes, which disappear in the Hubble image. These black holes are the most distant ever detected, or the galaxies in which they reside are so dusty that they cannot be seen.

Chandra/Hubble Comparison Animation of CDFN
QuickTime

• High Res (6.4 MB)

MPEG

• Low Res (2.3 MB)

This video compares the large area in the northern Chandra Deep Field, observed with the Chandra X-ray Observatory, with the smaller region viewed with Hubble's Advanced Camera for Surveys. The video begins with the Chandra field, which is over half the size of the full moon, and then zooms into the field to show several supermassive black holes [the red blobs], before dissolving to the Hubble image. Astronomers discovered that the positions of the black holes matched the location of the galaxies in the Hubble image.
