Sunrise Arc (NIRCam Compass Image)

Image titled “James Webb Space Telescope; WHL J013719.8-082841” with compass arrows, scale bar, and color key. In the center is a near-infrared image of a field of galaxies with one very bright star. At the lower left are compass arrows indicating the orientation of the image on the sky. The east arrow points toward 7 o’clock. The north arrow points toward 11 o’clock. At the bottom right is a scale bar labeled 30 arcseconds. The length of the scale bar is about one tenth of the total image. Below the image is a color key showing which NIRCam filters were used to create the image and which visible-light color is assigned to each filter. NIRCam filters from left to right: F090W, F115W, and F150W are blue; F200W is cyan, F277W is green; F356W is yellow, F410M is orange, and F444W is red.

This is an image of the WHL0137-08 galaxy cluster, which includes the Sunrise Arc galaxy, with compass arrows, scale bar and color key. The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above).

This image shows invisible near-infrared wavelengths of light that have been translated into visible-light colors. The color key shows which NIRCam (Near-Infrared Camera) filters were used when collecting the light. The color of each filter name is the visible light color used to represent the infrared light that passes through that filter. Below the image is a color key showing which NIRCam filters were used to create the image and which visible-light color is assigned to each filter.

  • Distance
    DistanceThe physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
    The star is approximately 12.9 billion light-years away.

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

This image is a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. 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:  Blue: F090W + F115W + F150W, Cyan: F200W, Green: F277W, Yellow: F356W, Orange: F410M,  Red: F444W

A black background is scattered with hundreds of small galaxies of different shapes, ranging in color from white to yellow to red. Some galaxies, mostly the redder galaxies, are distorted, appearing to be stretched out or mirror imaged. Just a little bit above the center, there is a bright source of light, a star, with 8 bright diffraction spikes extending out from it. Below the star are several noticeably fuzzy white galaxies that resemble cotton balls – these are part of a galaxy cluster. To the lower right of the star is a particularly long, red, thin line stretching from one o’clock to 7 o’clock. This is the Sunrise Arc.

The image is split in half vertically to create two images. In the left image, a black background is scattered with hundreds of small galaxies of different shapes, ranging in color from white to yellow to red. Some galaxies, mostly the redder galaxies, are distorted, appearing to be stretched out or mirror imaged. Just a little bit above the center, there is a bright source of light, a star, with 8 bright diffraction spikes extending out from it. The right image is a zoomed-in portion of the image at the left, showing a particularly long, red, thin line that stretches from 1 o’clock to 7 o’clock. There are several bright dots, some thicker than others, along this line, with one labeled as Earendel.
