A pioneering new study has shown that water found on Earth predates the formation of the sun – raising hopes that life could exist on exoplanets, the planets orbiting other stars in our galaxy.
The ground-breaking research set out to discover the origin of the water that was deposited on the Earth as it formed.
It found that a significant fraction of water found on Earth, and across our solar system, predates the formation of the sun. By showing that water is ‘inherited’ from the environment when a star is born, the international team of scientists believe other exoplanetary systems also had access to an abundance of water during their own formation.
