Meteorites show transport of material in early solar system

New studies of a rare type of meteorite show that material from close to the Sun reached the outer solar system even as the planet Jupiter cleared a gap in the disk of dust and gas from which the planets formed. The results, ...

Meteorite study suggests Earth may have been wet since it formed

A new study finds that Earth's water may have come from materials that were present in the inner solar system at the time the planet formed—instead of far-reaching comets or asteroids delivering such water. The findings ...

Meteorite strikes made life on Earth possible

Meteorites from the far reaches of the solar system delivered large amounts of water, carbon and volatile substances to the Earth. Only then could the Earth host life. Dr. María Isabel Varas-Reus, Dr. Stephan König, Aierken ...

Ion beams and atom smashers: secrets of moon rocks

Moon samples collected by the Apollo astronauts a half-century ago hold answers to questions that weren't even on scientists' minds at the time, as new technological tools provide insight into some of the oldest mysteries ...

Team identifies water-bearing minerals on asteroid Bennu

A Southwest Research Institute-led team discovered evidence of abundant water-bearing minerals on the surface of the near-Earth asteroid (101955) Bennu. Using early spectral data from NASA's OSIRIS-REx spacecraft orbiting ...

The composition of ancient meteorites

A team of Japanese and American scientists has visualized meteorite components at higher resolution than ever before. Their efforts have resulted in an enhanced understanding of substances inside carbonaceous chondrites, ...
