   JWST Sees the Same Supernova Three Times in an Epic Gravitational Lens

   Thanks to a powerful gravitational lens, astronomers were fortunate enough to see the same supernova three times in a distant galaxy. The lens is the galaxy cluster RX J2129, located about 3.2 billion light-years from Earth. When examining the region, researchers noticed that one of the lensed galaxies is duplicated three times - and they all contain the same supernova. Because the light took different paths, the same supernova is seen hundreds of days apart, showing its evolution in a single image.
