How Astronomers are Hunting Ancient Stars

At 4.6 billion years old, our beloved Sun is considered young when compared with the 13-billion-year-old stars that occupy the furthest reaches of our galaxy. Those stars, called “pristine” by astronomers, took shape just 300 million years after the Big Bang and are recognizable by a lighter metallic composition. Various teams of astronomers are currently on the hunt for these stars, looking into the night sky from telescopes located in Australia, and more recently, Chile. Head to The Atlantic to learn how they’re tracking them down.
