Meteorites reveal how they brought space water to Earth

Space rocks that fall to Earth are ancient time capsules, and scientists who merged two imaging techniques may be able to tell us if and how they brought water to Earth. 

Meteorites are shards that have broken off of larger objects such as comets or asteroids, and it is thought that asteroids and comets from the outer reaches of the solar system may have left water on nascent Earth after impact. To find out whether they really did carry over water from beyond our planet, a research team from the National Institute of Standards and Technology (NIST) came up with a method of simultaneously using X-ray and neutron imaging to get a glimpse inside a meteorite and determine what it might have been hiding for billions of years.
