They detected chemical signatures of heavy water – which is around 10% more denser than ordinary water – in the star’s rotating disc of gas and dust

Scientists believe they have uncovered more evidence that water on Earth may be older than the sun.

An international team of researchers used data from ground-based telescopes to ascertain the chemical composition of a young star, known as V883 Orionis, in the Orion constellation.
