Samples of Ryugu Asteroid , Contain Clues About, Our Solar System.br 'Newsweek' reports that a new study has br revealed that ancient asteroid samples contain br clues about Earth and the early solar system.br The study presents the findings br from the 2019 Japanese Hayabusa2br mission by state space agency JAXA.br The spacecraft retrieved br 5 grams of samples from br the asteroid Ryugu.br According to researchers at the Japan Agency for Marine-Earth br Science and Technology, particles from the asteroid are "pristine" br and offer never before seen clues about the solar system.br Ryugu particles are the most br uncontaminated and unfractionated br extraterrestrial materials studied so far, br and provide the best available match br to the bulk Solar System composition, Japan Agency for Marine-Earth Science br and Technology study, via 'Newsweek'.br 'Newsweek' reports that these untouched br particles could provide vital information br on how life was formed on Earth.br Volatile and organic-rich br C-type asteroids may have br been one of the main br sources of Earth's water, Japan Agency for Marine-Earth Science br and Technology study, via 'Newsweek'.br Our best insight into their chemistry br is currently provided by carbonaceous br chondritic meteorites, but br the meteorite record is biased: , Japan Agency for Marine-Earth Science br and Technology study, via 'Newsweek'.br ... only the strongest types br survive atmospheric entry and br are then modified by interaction br with the terrestrial environment, Japan Agency for Marine-Earth Science br and Technology study, via 'Newsweek'.br Details of the team's findings were br published in 'Nature Astronomy.
