JWST’s first triple-image supernova could save the Universe

Astronomers have discovered a triply-lensed supernova in a distant galaxy, which could help resolve the mystery of the Universe’s expansion rate. The supernova, spotted by the James Webb Space Telescope (JWST), is the second-most distant ever observed. The discovery could enable more accurate measurements of the Universe’s expansion by using the supernova as a “standard candle”. The study also revealed three separate galaxy groups in the region of space behind the supernova, further enhancing its scientific significance.
