Palomar Observatory spots a gravitationally lensed supernova (page 2)

A Swedish-led team of astronomers used the NASA/ESA Hubble Space Telescope to analyze the multiple images of a gravitationally lensed type Ia supernova for the first time. The four images of the exploding star will be used to measure the expansion of the Universe. This can be done without any theoretical assumptions about the cosmological model, giving further clues about how fast the Universe is really expanding. The results are published in the journal Science.
