They found dust grains within the space rock – which fell to Earth in the 1960s – that are as much as 7.5 billion years old.
The oldest of the dust grains were formed in stars that roared to life long before our Solar System was born.
A team of researchers has described the result in the journal Proceedings of the National Academy of Sciences.
“They’re solid samples of stars, real stardust,” said lead author Philipp Heck, a curator at Chicago’s Field Museum and associate professor at the University of Chicago.
