 In the How Old Is It? video book segment on the Lambda Coal Dark Matter Big Bang benchmark model, we covered the dark ages between the release of the cosmic background radiation photons and the first light from stars formed from hydrogen, helium and lithium, the only elements available in the universe at that time. These are called population 3 stars. The earliest expected time for these stars is 150 million years after the Big Bang, using gravitational lensing created by the galaxy cluster Max J0416 and its surroundings. A team of astronomers using Hubble Space Telescope were able to see galaxies 10 to 100 times fainter than any previously observed, with ages as far back as 500 million years after the Big Bang. They found no evidence of these first generation population 3 stars. The Big Bang theory has it that there should be plenty of them. This creates a mystery that might be resolved by the new James Webb Space Telescope.
