Which instruments were used to construct the Hubble Ultra Deep Field (HUDF) image?

Answer

Advanced Camera for Surveys (ACS) and Near Infrared Camera and Multi-Object Spectrometer (NICMOS)

The construction of the Hubble Ultra Deep Field (HUDF) required significant technical refinement, specifically utilizing data gathered by two key instruments: the Advanced Camera for Surveys (ACS) and the Near Infrared Camera and Multi-Object Spectrometer (NICMOS). These instruments were crucial because they provided the necessary sensitivity to capture the faintest, reddest light traveling from the earliest epochs of the universe. Peering into the infrared spectrum is essential as the expansion of the universe stretches the light from the most distant objects out of the visible range through a process known as redshift.
