JWST's Groundbreaking Discoveries: Unveiling Supernova Secrets

Using the James Webb Space Telescope (JWST), astronomers have discovered a new Type I supernova in the galaxy cluster PLCK G165.7+67.0. The supernova, named SN H0pe, was detected in a gravitationally amplified galaxy and offers a unique opportunity to determine Hubble's constant by measuring the time delays between its multiple images. Further investigation revealed the properties of the host galaxy and the cluster itself. More results will be published in an upcoming research paper.
