This is the deepest image of the universe ever captured (for now)Webb shows off what its calibrated equipment is capable of. But you'll have to wait until next week for the first full-color photo.BY HARRY GUINNESS | PUBLISHED JUL 7, 2022 6:49 PMThis Fine Guidance Sensor test image was acquired in parallel with NIRCam imaging of the star HD147980 over a period of eight days at the beginning of May. This engineering image represents a total of 32 hours of exposure time at several overlapping pointings of the Guider 2 channel. 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. The unfiltered wavelength response of the guider, from 0.6 to 5 micrometers, helps provide this extreme sensitivity. The image is mono-chromatic and is displayed in false color with white-yellow-orange-red representing the progression from brightest to dimmest. The bright star (at 9.3 magnitude) on the right hand edge is 2MASS 16235798+2826079. There are only a handful of stars in this image - distinguished by their diffraction spikes. The rest of the objects are thousands of faint galaxies, some in the nearby universe, but many, many more in the distant universe. NASA, CSA, and FGS team.
The first scientific full-color photos from NASA's James Webb Space Telescope (JWST), the successor to Hubble, are due to be released on July 12. But, to get everyone excited, NASA has just dropped an incredible shot of deep space, captured by Webb's Fine Guidance Sensor (FGS), incidentally, during other testing. According to NASA, it is, at least for a few more days, the deepest image of the universe ever captured and "provides a tantalizing glimpse at what the telescope's science instruments will reveal in the coming weeks, months, and years."More here:
