Volatile and organic-rich C-type asteroids may have been one of the main sources of Earth's
water. Our best insight into their chemistry is currently provided by carbonaceous chondritic …

Meteorites are a remarkable resource. They capture the imagination of people worldwide
with their spectacular entry through Earth's atmosphere as fireballs, and their exotic …

Chondrule-like objects and Ca-Al-rich inclusions (CAIs) are discovered in the retuned
samples from asteroid Ryugu. Here we report results of oxygen isotope, mineralogical, and …

The delivery of water to the inner Solar System, including Earth, is still a debated topic. A
preferential role for hydrated asteroids in this process is supported by isotopic …

Samples from asteroid Ryugu returned by the Hayabusa2 mission contain evidence of
extensive alteration by aqueous fluids and appear related to the CI chondrites. To …

C-type asteroids are the source of the carbonaceous chondrite meteorites and represent
remnants of primitive planetesimals that formed at the outer margins of the early Solar …

Micrometeorites, a possible major source of Earth's water, are thought to form from explosive
dispersal of hydrated chondritic materials during impact events on their parental asteroids …

The extraterrestrial materials returned from asteroid (162173) Ryugu consist predominantly
of low-temperature aqueously formed secondary minerals and are chemically and …

Samples returned from the carbonaceous asteroid (162173) Ryugu by the Hayabusa2
mission revealed that Ryugu is composed of materials consistent with CI chondrites and …

Carbonaceous chondrites are considered to have originated from C-type asteroids and
represent some of the most primitive material in our solar system. Furthermore, since …
