Portion of Cosmic Evolution Early Release Science (CEERS) Survey (NIRCam Compass Image) | Webb
This is a portion of the Cosmic Evolution Early Release Science (CEERS) Survey, made up of several near-infrared pointings from NIRCam (the Near-Infrared Camera) aboard the James Webb Space Telescope. These observations are within the same region studied by the Hubble Space Telescope, which is known as the Extended Groth Strip. 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 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. The scale bar is labeled in arcseconds, which is a measure of angular distance on the sky. One arcsecond is equal an angular measurement of 1/3600 of one degree. There are 60 arcminutes in a degree and 60 arcseconds in an arcminute. (The full Moon has an angular diameter of about 30 arcminutes.) The actual size of an object that covers one arcsecondĀ on the sky depends on its distance from the telescope. Credit: STScI.
