These Gravitationally Lensed Supernovae Could Resolve The Hubble Tension

Researchers used the JWST to find a pair of strong gravitationally lensed Supernovae. They exploded billions of years ago, and their light is just reaching us now. Because of the lensing, we’ll see multiple images of them, separated by years or decades. This could reveal the expansion rate of the Universe, and provide a solution to the Hubble Tension.
