Water filling the Earth’s oceans is older than the formation of the sun, increasing the chances of life emerging among the stars



The sun is thought to be 4.5 billion years old, but water on Earth may have formed before then as tiny crystals of ice floating around deep space.

Professor Tim Harries, from the University of Exeter, said: ‘We know that water is vital for the evolution of life on Earth, but it was possible that the Earth’s water originated in the specific conditions of the early solar system, and that those circumstances might occur infrequently elsewhere.

‘By identifying the ancient heritage of Earth’s water, we can see that the way in which our solar system was formed will not be unique, and that exoplanets will form in environments with abundant water. 

‘It raises the possibility that some exoplanets could house the right conditions, and water resources, for life to evolve.’

The international team of scientists studied ancient ices preserved in comets and asteroids since the early days of the solar system.
