Meteor carrying extra-terrestrial water discovered in the UK

UK:The United Kingdom’s famous meteorite which landed in a Gloucestershire garden last year has been discovered to contain extra-terrestrial water.

In February 2021, the space rock spectacularly descended to earth before finishing its journey on the driveway in Winchcombe.

Following its discovery as the first meteorite of its kind to be recovered in the UK in 30 years, scientists have been busy analysing its composition in order to learn more about the surrounding universe.

As it was collected so soon after landing, the 0.5kg rock – made up of 12 per cent water – hadn’t been contaminated and therefore provided some key insights into where the water in our planet’s oceans comes from.

King said, “One of the big questions we have in planetary sciences is where did the water on earth come from?

“Were comets the main source, were asteroids the main source?” Meteorite terrestrial water discovery

“The composition of water on comets, at least a few that we visited, doesn’t really match the earth’s oceans, but the composition of the water in the Winchcombe meteorite is a much better match. Meteorite terrestrial water discovery

“So that would imply that carbonaceous asteroids were probably the main source of water for earth.”

The scientist, who is also part of the UK Fireball Alliance, explained it’s the first time a meteorite containing extra-terrestrial water has landed in the UK.

King continued: “What’s really exciting for us for us is that Winchcombe meteorite was collected about 12 hours after landing, so the water that’s in the rock hasn’t been contaminated with the water that we have in our atmosphere.

“So it’s basically really fresh. We can be really confident when we measure the water that it is extra-terrestrial water. The composition of that water is very, very similar to the composition of the water in the earth’s oceans. So it’s a really good piece of evidence that asteroids and bodies like Winchcombe were delivering really important contributions to the earth’s oceans. It’s also got 2 percent carbon, and a significant fraction of that is organic materials, like amino acids. If you want to start making DNA and stuff, you need amino acids, so all of these starting materials are locked up in the Winchcombe meteorite.”

The scientist explained that space rock came from a larger carbonaceous asteroid, believed to have formed around 4.6 billion years ago.

Analysis suggests the meteorite broke off before taking some 300,000 years to finally reach its destination – a Gloucestershire back garden.
