Astronomers sharpen universe’s expansion rate, deepening cosmic mystery
Overview: A more precise measure of the universe’s speed Recent work by a diverse group of astronomers has yielded one of the most precise independent measurements of the Hubble constant, the rate at which the universe is expanding. By combining data from ground- and space-based telescopes—including the W. M. Keck Observatory atop Mauna Kea—the team…

Astronomers Sharpen Universe’s Expansion Rate, Deepening Cosmic Mystery
New Measurements Tighten the Grip on Cosmic Expansion Astronomers from multiple observatories have produced one of the most precise independent estimates of how fast the universe is expanding. By combining data from ground-based facilities and space telescopes, including the W. M. Keck Observatory on Mauna Kea, the team has added a critical data point to…
