New data released today by the Atacama Cosmology Telescope (ACT) in Chile indicate our universe is around 13.8 billion years old, matching the measurements made by the Planck satellite in 2015, and calling into question the 2019 findings of another research group that determined the age of the universe to be much younger than what the Planck satellite had predicted. That study had measured the movement of galaxies to come up with their number, while the ACT measured polarized light to reach its conclusions.
