The image above shows the gravitationally lensed iPTF16geu Type Ia supernova. (W.M. Keck Observatory) For the first time, a team of researchers has witnessed the cosmic magnification of a Type Ia supernova, which could allow them to calculate the rate at which the universe is expanding. and astronomers frequently use them to measure how fast the universe is spreading, as well as its amount of dark energy, according to a release on the discovery. In a recent study, the scientists...
