Zoom on the COSMOS field (UltraVISTA)
August 1, 2013 · ESA/Hubble
This video offers a zoom on the COSMOS survey, a detailed map of a patch of sky roughly 10 times the size of the area covered by the full Moon. This field has been studied by Hubble and other telescopes at different wavelengths. The Hubble image was taken using a single filter, meaning that it appears in black and white (Hubble's F814W, or I-band, filter).
The final detailed infrared view in this zoom sequence comes from the VISTA telescope at ESO's Paranal Observatory.
Data from the COSMOS survey has been used for much important research, including creating a 3-dimensional map of the Universe's dark matter distribution, and a study into the relationship between major mergers of galaxies and active galactic nuclei.
