Where did water come from on Earth? This meteorite may reveal the mystery

If you've ever wondered where water on Earth comes from, a new UK study may have the answer.

That's after researchers from London's Natural History Museum and the University of Glasgow, in Scotland, studied a meteorite that fell into the yard of an English family last year in the town of Winchcombe, Gloucestershire, discovering that it contained water similar to that found on Earth.

"It's a crystal clear window into our early solar system," Luke Daly, co-author of the study and a lecturer in planetary geosciences at the University of Glasgow, told CNN.

Published in the journal Science Advances on Wednesday, the study reveals that extraterrestrial rocks may have brought vital chemical compounds — such as water — to our planet billions of years ago, creating the oceans and all life on Earth.

Approximately 71% of the Earth's surface is covered by water, with the oceans holding about 96.5% of all water.

Imaging and chemical analysis of the Winchcombe meteorite – as it has become known – revealed that it contains around 11% water and 2% carbon by weight, making it the first of its kind found in the UK.

The team, which measured the ratio of hydrogen isotopes in the water, found that it closely resembled the composition of water on Earth, according to a press release from the Natural History Museum.

Extracts from the rock also found extraterrestrial amino acids, making it stronger evidence that water and organic material were delivered to the planet by asteroids like the one from which Winchcombe broke away.

The meteor was identified as a CM carbonaceous chondrite, a type of stony meteorite that contains a high composition of components that predate the solar system.

Recovered within 12 hours of its landing with the help of the UK Fireball Alliance, an organization which aims to recover meteorites that have just fallen in the UK, it had very little time to be changed by the Earth's atmosphere.

"We know that everything inside it is 100% extraterrestrial, including 11% of the water it contains," Daly said.

While this paper is the first of many publications that are in the works on the meteorite, Daly said it will keep them busy for years. "Of course there are many other stories and secrets carried in this particular stone," he added.
