Thanks to the Hubble Space Telescope, this area is captured in the deepest images of the universe ever made by humankind at optical and near-infrared wavelengths. The relative brightness of the galaxy at different wavelengths is influenced by the expanding universe, and allows astronomers to estimate its distance. Galaxies grew from small clumps of stars to ever-bigger assemblages. Hubble's Advanced Camera for Surveys (ACS) does not see the galaxy at all, despite the fact that the Ultra Deep Field is the deepest image ever alien in optical light. Another galaxy's central disk of gas and dust may be slightly warped. The galaxy was detected using Hubble's infrared camera, the Near Infrared Camera and Multi-Object Spectrometer (NICMOS), and also with an infrared camera on the Very Large Telescope (VLT) at the European Southern Observatory, but at those wavelengths it is very faint and red.
