Using NASA/ESA Hubble and ESA’s Gaia space telescopes, Riess et al have made the most precise measurements to date of the Universe’s expansion rate. This is calculated by gauging the distances between nearby galaxies using special types of stars called Cepheid variables as cosmic yardsticks. By comparing their intrinsic brightness as measured by Hubble, with their apparent brightness as seen from Earth, scientists can calculate their distances. Gaia further refines this yardstick by geometrically measuring the distances to Cepheid variables within the Milky Way Galaxy. This allowed astronomers to more precisely calibrate the distances to Cepheids that are seen in outside galaxies. Image credit: NASA / ESA / A. Field, STScI.
