The Secret Lives Of Galaxies Unveiled In Deep Survey

NASA,

DESCRIZIONE

*Description*:> This video compares the large area in the northern GOODS 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.
