Samples of a 4.5 billion-year-old asteroid may reveal the origins of life on the planet.
The teaspoon-sized specimen, taken from asteroid Bennu, is being examined by scientists on the Natural History Museum (NHM).
The black dust-like pattern may assist make clear among the largest questions on how Earth was shaped.
It may maintain very important clues to the formation of the planets and our photo voltaic system, specialists say.
Professor Sara Russell, senior analysis lead on the NHM, stated: “We’re really excited at the moment because we’ve just taken receipt of a tiny teaspoonful of black powder, but it’s actually come from space.”
She added: “We’re really excited to get a piece of asteroid Bennu because we believe that this asteroid dates from the very earliest times of the solar system, when the solar system and the sun and the planets were forming four and a half billion years ago.
“It shaped from a swirling disc of mud and gasoline, and we predict that we’d have elements right here of that point interval.”
Prof Russell has already been analyzing the pattern, which is contained in a nitrogen glovebox, that means it’s not being contaminated by being uncovered to air, to protect its pure state.
The activity entails standing in entrance of the sealed field and utilizing the connected gloves to conduct experiments.
Explaining what the pattern might include, she stated: “It also, we think, contains minerals like clays that trap loads of water, so it might contain loads of water and that could tell us how the Earth got to be a watery habitable planet.
“Also, we predict that it would include a number of per cent of carbon, which may be within the type of natural carbon, so we have to examine that additional.
“But it could be that asteroids like Bennu also provided the nutrients that were needed for life to flourish on Earth.”
In September NASA Osiris-Rex (Origins, Spectral Interpretation, Resource Identification and Security – Regolith Explorer), turned the primary US mission to gather a pattern from an asteroid and return it to Earth.
Scientists on the NHM are amongst a global group who’ve acquired among the pattern to analyse.
Bennu is a carbon-rich asteroid, containing roughly 5% by mass, a few of which is natural.

The group additionally consider it may have extra-terrestrial water trapped inside its minerals.
Analysis of those minerals will assist the group take a look at the speculation that asteroids delivered water to our planet 4.5bn years in the past.
Prof Russell stated: “When the Earth formed it was probably formed really, really hot, and things like water would have just boiled up and escaped into space, it would have been very dry when it first formed.
“So the query is, how did we get to be on this lovely blue planet that is lined in oceans?
“And it’s likely that the answer is because water was brought to it by impact of asteroids and comets from the outer solar system.”
The Museum is certainly one of 4 UK institutes learning samples from NASA, together with the Open University, Oxford University and the University of Manchester.
