NASA officials stated that the James Webb Space Telescope has ever captured “the deepest, clearest infrared image of the early universe” dating back 13.8 billion years.
The clearest image ever taken by the James Webb Space Telescope, showing the vast universe filled with thousands of galaxies. US President Biden made the statement. “This telescope is one of humanity’s greatest engineering achievements,” Biden said.
The Webb telescope used the galaxy cluster SMACS 0723 as a cosmic magnifying glass, looked at the extremely distant and faint galaxies behind this galaxy cluster and recorded the image. The super telescope was able to take clear pictures thanks to “gravitational lensing,” which uses the mass of the foreground galaxy to bend the light of objects behind the galaxy, such as a pair of glasses.
James Webb’s primary imaging device, the Near Infrared Camera (NIRCam), brought these faint background galaxies into sharp focus. Webb took just 12.5 hours to render the image, which could take weeks.
