Colliding galaxies, gas-giant exoplanets and dying star systems were the first celestial subjects captured on camera by the JWST.
The telescope is 100 times more sensitive than its 30-year-old predecessor, the Hubble Space Telescope, which is still operational.
JWST’s discoveries may turn out to be accidental or answers to questions astronomers have yet to ask.
René Doyon, principal investigator for one of Webb’s instruments, the Near-Infrared Imager and Slitless Spectrograph, said: “Who knows what’s coming for JWST. But I’m sure we’re going to have a lot of surprises.”
