New View of Nature’s Oldest Light Adds Fresh Twist to Debate Over Universe’s Age

Simons Foundation, July 2020

From a mountain high in Chile’s Atacama Desert, astronomers with the National Science Foundation’s Atacama Cosmology Telescope (ACT) have taken a fresh look at the oldest light in the universe. Their new observations plus a bit of cosmic geometry suggest that the universe is 13.77 billion years old, give or take 40 million years.

Led media push for newest findings from the Atacama Cosmology Telescope, coordinating with dozens of other institutions. Media coverage in New Scientist, Science News, BBC, Nature, USA Today, UPI and Express.
