NASA's Webb Telescope will extend Hubble's work
NASA announced Thursday that its Hubble Space Telescope (HST) has calibrated more than 40 "milepost markers" of space and time.
The mile markers help scientists measure the expansion rate of the universe and astronomers have found – using data from the HST and other telescopes – a discrepancy between the expansion rate as measured in the local universe compared to independent observations following the big bang.
The cause of the discrepancy remains unknown, but NASA said HST data supports new physics.
The expansion rate of the universe is called the "Hubble constant," after Edwin Hubble.
