JWST Advanced Deep Extragalactic Survey (JADES)

On a black background, two white, rectangular outlines are connected at one corner. Within the two outlines are hundreds of small galaxies of all colors.

This image taken by the James Webb Space Telescope highlights the region of study by the JWST Advanced Deep Extragalactic Survey (JADES). This area is in and around the Hubble Space Telescope’s Ultra Deep Field. Scientists used Webb’s NIRCam instrument to observe the field in nine different infrared wavelength ranges. From these images, the team searched for faint galaxies that are visible in the infrared but whose spectra abruptly cut off at a critical wavelength. They conducted additional observations (not shown here) with Webb’s NIRSpec instrument to measure each galaxy’s redshift and reveal the properties of the gas and stars in these galaxies.

In this image blue represents light at 1.15 microns (115W), green is 2.0 microns (200W), and red is 4.44 microns (444W).
