Webb telescope’s sharp views of the universe will change astronomy

But the most striking result came from a comparison of images taken of the same target by Webb’s Mid-Infrared Instrument with the now-retired Spitzer Space Telescope’s Infrared Array Camera. NASA/JPL-Caltech; NASA/ESA/CSA/STScI “You can appreciate that the images from Webb are going to be better because we have 18 segments, every one of which is larger than the single segment, so to speak, that formed the Spitzer telescope’s mirror,” said Marcia Rieke, principal investigator for Webb’s Near-Infrared Camera and regents professor of astronomy at the University of Arizona, during the news conference. The first images Webb’s first images of the universe, called the early release observations, or EROs, are expected to come out in mid-July, said Klaus Pontoppidan, Webb project scientist at the Space Telescope Science Institute in Baltimore, during the press conference.
