A new, precise measurement of the expansion rate of the Universe is in, and it's serving up a huge cosmic pickle.
Using Hubble data and new observations from the James Webb Space Telescope (JWST), a team led by physicist Adam Riess of Johns Hopkins University has confirmed that previous measurements are correct after all, despite years of debate.
Based on immense distances from our Solar System to Cepheid variable stars and Type Ia supernovae, which are used to create a 'cosmic distance ladder', our Universe does indeed appear to be expanding at 73 kilometers per second per megaparsec – a rate known as the Hubble constant. READ MORE...
