Astronomers want new ways to measure distance in the Universe, working to calculate its rate of expansion. A new image from JWST contains a gravitational lens of a background galaxy. And in that galaxy are three versions of the same Type 1a supernova, one of the most distant ever seen. With this supernova, astronomers are able to extend their distance ladder out by billions of years, and yet, it doesn't resolve the famous Hubble Tension; it only confirms it.
