The universe is about 13.8 billion years old, but how do we know that?

  In 2013, the Hubble Space Telescope found the birth certificate of oldest known star in the universe, cataloged as HD 140283, aptly named “methuselah”. The star, located in the constellation Libra, which is at the very first stages of expanding into a red giant, could be as old as 14.5 billion years (plus or minus 0.8 billion years), which at first glance would make it older than the universe’s calculated age of about 13.8 billion years, creating what we commonly call a dilemma. The st...

January 12, 2021 New work agrees with older research suggesting the oldest light in the universe – from the most distant galaxy yet known – started its journey toward us 13.77 billion years ago. View larger. | In 2013, the Planck space telescope released the most detailed map to date of the cosmic microwave background, the relic radiation from the Big Bang. It was the mission’s first all-sky picture of the oldest light in our universe, imprinted on the sky when it was just 380,000 years ...

Ideas, Inventions And Innovations New View of Nature’s Oldest Light Suggest Universe Is 13.77 Billion Years Old From an observatory high above Chile’s Atacama Desert, astronomers have taken a new look at the oldest light in the universe. Their observations, plus a bit of cosmic geometry, suggest that the universe is 13.77 billion years old – give or take 40 million years. A Cornell researcher co-authored one of two papers about the findings, which add a fresh twist to an ongoing debate...
