Webb Observations of HUDF (NIRCam Image)

A rectangular image that appears to be two square images separated by a wide black gap. The gap obscures the galaxies present between the two square images. Each square image contains thousands of galaxies with many different colors. Some galaxies are shades of yellow, while others are white, blue, orange and red. Most of these galaxies appear as fuzzy ovals, but others appear thin and long. A few galaxies with distinct spiral arms are spread throughout.

This image of the Hubble Ultra Deep Field was taken by the Near-Infrared Camera on NASA’s James Webb Space Telescope. 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).

Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

These images are a composite of separate exposures acquired by the James Webb Space Telescope using the MIRI instrument. Several filters were used to sample wide wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F182M, Cyan: F210M, Green: F430M, Orange: F460M, Red: F480M
