NASA Announces New, Milestone in Mystery, of Universe's Expansion Rate.On May 19, NASA announced that the Hubble Space Telescope (HST) has now calibrated over 40 "milepost markers" of space and time.Fox reports that these markers help scientist measure the expansion rate of the universe, otherwise known as the "Hubble constant.".Astronomers have now found a discrepancy between the expansion rate of the local universe compared to observations following the big bang.According to Fox, the cause of the discrepancy remains unclear, but NASA claims that the HST data may support new physics.A nationwide scientific collaboration called Supernova, H0, for the Equation of State of Dark Energy (SH0ES) looked at 42 Type Ia supernovae with Hubble.The SH0ES project was designed to bracket the universe by matching the precision of the Hubble constant inferred from studying the cosmic microwave background radiation leftover from the dawn of the universe, Adam Riess, Space Telescope Science Institute (STScI) and the Johns Hopkins University, via Fox.The SH0ES project was designed to bracket the universe by matching the precision of the Hubble constant inferred from studying the cosmic microwave background radiation leftover from the dawn of the universe, Adam Riess, Space Telescope Science Institute (STScI) and the Johns Hopkins University, via Fox.According to NASA, the expansion rate was previously predicted to be slower than what the HST data revealed. .SH0ES found the expansion rate to be more than double the prior sample of cosmic distance markers. .Fox reports that NASA's new Webb Space Telescope will allow astronomers to show mile markers at a greater distance and extend the work started by the Hubble.Fox reports that NASA's new Webb Space Telescope will allow astronomers to show mile markers at a greater distance and extend the work started by the Hubble
