Earth's water came from space, but not in the way we thought

ABC  

Earth has vast oceans today, but our planet was a dry rock when it first formed — and water was a late addition, rained down in asteroids from the icy outer solar system. Key points: Water is abundant in space but it was thought that Earth was dry when it formed A new study shows that meteorite rocks of the type that built the Earth contain the building blocks of water This means that water formed on Earth from day one rather than being a later addition Water is abundant in space and is made up of hydrogen created in the Big Bang and oxygen released from dying stars. "At least three times the amount of water in the Earth's oceans can be provided by these enstatite chondrites," said Dr Piani. "To explain the water in the oceans we still need a bit of water from the outer solar system," she said.
