Hubble Tension Is Currently In Our Cosmic Backyard

New data shows that the Coma Cluster of galaxies appears 38 million light-years closer than it ought to be to us. Scientists struggle today to precisely measure how fast the universe expands following Hubble-Lemaître's rule. Based on cosmic expansion models our observations show that objects speed away from us at a rate which equals the Hubble constant times their distance. The farther a galaxy is from Earth the faster it moves away from our planet. Researchers Dan Scolnic of Duke University and Adam Riess of Johns Hopkins University located all type Ia supernovas in the Coma Cluster of galaxies as seen by the Hubble Space Telescope. What we learned from studying these astronomical events tells us the Coma Cluster lies near us than its expected spot according to current models. Research groups use two standard ways to determine the Hubble constant. Scientists estimate galactic distances using standard candles which have known brightness amounts
