The James Webb Space Telescope has surprised scientists when it unexpectedly discovered its first supernova, an explosion from a dying star. The evidence could potentially open up a whole new field of research opportunities, scientists say.

Only a few days after the start of scientific operations, the James Webb Space TelescopeThe NIRCam camera of discovered an unexpectedly bright object in a galaxy called SDSS.J141930.11+5251593, about 3 to 4 billion light years out Earth. The bright object dimmed over a period of five days, suggesting that it was a supernova, caught by sheer luck shortly after the starburst. (The astronomers compared the new observations with archived data from the Hubble Space Telescope to confirm the light was new.)
