Astronomers are looking again. It seems that they can’t agree on the age of the universe, which is calculated from the Hubble constant.
Last year new measurements were made using the orbiting Hubble telescope focused on the galaxy cluster in the constellation Virgo. These were to be the most accurate measurements yet. But when the answers came in, the universe appeared to be younger than the oldest stars (8-11 billion years for the age of the universe as compared to 15 billion years for the oldest stars).
