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 Hayabusa2<br />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.'
