Astronomers have discovered the oldest star in the universe since the Big Bang. The ancient star is believed to be over 13 billion-years-old.
Being the oldest star in the universe, the new discovery has given astronomers a chance to look into the chemistry of the first stars. With this latest find, scientists have the opportunity to get a better understanding of how the universe was formed after the Big Bang.
The 13.7 billion-year-old star was discovered by The Australian National University using the SkyMapper telescope at the Siding Spring Observatory. ANU lead researcher Dr. Stefan Keller stated in the scientific journal Nature:
“This is the first time that we’ve been able to unambiguously say that we’ve found the chemical fingerprint of a first star. This is one of the first steps in understanding what those first stars were like. What this star has enabled us to do is record the fingerprint of those first stars.”
What is interesting about this ancient star is its proximity to Earth. The oldest star in the universe is relatively close being 6,000 light years away. Ancient stars are unlike younger stars such as the Sun. While the Sun and modern stars carry heavy amounts of iron, ancient stars are more polluted and carry small amounts of iron with much more carbon.
Known as primordial stars, it was initially believed that ancient stars died out with huge supernova explosions. However, this new discovery indicates a low supernova explosion and has the potential to solve discrepancies with the Big Bang Theory.
