"Webb Telescope Discovers Ancient Supernova Through Gravitational Lens"

The Webb Space Telescope has captured images of a supernova in the ancient universe, magnified by a gravitational lensed galaxy. Named Encore, this is the second supernova spotted in the lensed region, with the first one, Requiem, expected to reappear in 2035. Gravitational lenses allow astronomers to observe faint and distant light sources, providing insights into the size and expansion rate of the universe. Encore and Requiem are Type 1a supernovae, which are crucial for calculating the Hubble Constant and addressing the Hubble Tension.
