"Unveiling the Astonishing Weight Loss of a Massive Star Before Supernova"

The discovery of a distant supernova called SN H0pe, whose light has been magnified and triplicated by gravity, could help scientists determine the expansion rate of the Universe, known as the Hubble Constant. This Type Ia supernova, observed using the James Webb Space Telescope, has a time delay between its images due to gravitational lensing, making it a valuable tool for measuring the expansion rate. Further analysis and calculations are needed to determine the Hubble Constant, but this discovery holds promise for advancing our understanding of cosmology.
