NASA explains that the bright star (at 9.3 magnitude) on the right hand edge is 2MASS 16235798+2826079. It said that the unfiltered wavelength response of the guider, from 0.6 to 5 micrometers, helps provide this extreme sensitivity.Īccording to NASA, the image is mono-chromatic and is displayed in false color with white-yellow-orange-red representing the progression from brightest to dimmest. The observations were not optimized for detection of faint objects, but nevertheless the image captures extremely faint objects and is, for now, the deepest image of the infrared sky, NASA said. It represents 32 hours of exposure time at several overlapping pointings of the Guider 2 channel. In this image, the FGS image was acquired in parallel with NIRCam imaging of the star HD147980 over a period of 8 days at the beginning of May. NASA says that the engineering test image – produced during a thermal stability test in mid-May. Webb's Fine Guidance Sensor, built by to help it lock onto targets, recently captured this stunning test image - an unexpected peek into how Webb will #UnfoldTheUniverse: /SNe9zvtvfQ- NASA July 6, 2022 We’re less than a week away from first full-color images!
