North Ecliptic Pole Time Domain Field

A swath of sky measuring 2% of the area covered by the full moon was imaged with Webb’s Near-Infrared Camera (NIRCam) in eight filters and with Hubble’s Advanced Camera for Surveys (ACS) and Wide-Field Camera 3 (WFC3) in three filters that together span the 0.25 – 5-micron wavelength range. This image represents a portion of the full PEARLS field, which will be about four times larger. Thousands of galaxies over an enormous range in distance and time are seen in exquisite detail, many for the first time. Light from the most distant galaxies has traveled almost 13.5 billion years to reach us. Because this image is a combination of multiple exposures, some stars show additional diffraction spikes. This representative-color image was created using Hubble filters F275W (purple), F435W (blue), and F606W (blue); and Webb filters F090W (cyan), F115W (green), F150W (green), F200W (green), F277W (yellow), F356W (yellow), F410M (orange), and F444W (red).

These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument and the Hubble Space Telescope using the ACS/WFC and UVIS/WFC3 instruments. Several filters were used to sample specific 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: Purple: F275W, Indigo: F435W, Blue: F606W, Light-Blue: F090W, Cyan: F115W, Green: F150W, Yellow/Green: F200W, Yellow: F277W, Light-Orange: F356W, Orange: F410M, Red: F444W
