Talk about ancient. Astronomers from the Australian National University have discovered the oldest known star about 6,000 light-years from Earth. They believe the ancient star formed around 13.7 billion years ago, shortly after the Big Bang.
“This is the first time that we’ve been able to unambiguously say that we’ve found thechemical fingerprint of a first star,” lead researcher Dr. Stefan Keller, an astronomer at the university’s Research School of Astronomy and Astrophysics, said in a written statement.
A research team at the Siding Spring Observatory, which is part of the Research School, first observed the star (dubbed SMSS J031300.36-670839.3) on Jan. 2 using the SkyMapper telescope. Then, astronomers in Chile confirmed the discovery using one of the powerful Magellan telescopes.
