The “Big Bang Galaxy” –Brightest in the Early Universe at 13 Billion Years Old Discovered to Harbor Carbon

Until summer of 2018, the earliest stars in the universe were thought to lack elements heavier than helium, such as carbon, the building block for life on Earth. In 2015, astronomers at Leiden University discovered an extremely distant galaxy called CR7, by far the brightest from its epoch ever seen, which matched their prediction. Three years later, with measurements using the ALMA telescope they found to their surprise, that the galaxy does have carbon after all, and even in normal concentrations.
