Webb observes the Hubble Ultra Deep Field

On 11 October 2022, the NASA/ESA/CSA James Webb Space Telescope spent over 20 hours observing the long-studied Ultra Deep Field of the NASA/ESA Hubble Space Telescope for the first time. The general observer program (GO 1963) focused on analysing the field in wavelengths between approximately 2 and 4 microns. This image was taken by the Near Infrared Camera (NIRCam). 

The Webb image observes the field at depths comparable to Hubble – revealing galaxies of similar faintness – in just one-tenth as much observing time. It includes 1.8-micron light shown in blue, 2.1-micron light shown in green, 4.3-micron light shown in yellow, 4.6-micron light shown in orange, and 4.8-micron light shown in red (filters F182M, F210M, F430M, F460M, and F480M).

Note: This post highlights data from Webb science in progress, which has not yet been through the peer-review process

[Image Description: Two images are shown side-by-side of the same field of galaxies. Both images contain thousands of galaxies in various sizes, shapes, and colours.]
