The findings challenge the theory that radioactive isotopes trapped in meteorites from the dawn of our Solar System originated in a supernova. They also shed light on the origins of water on Earth, says a study in the journal Meteoritics and Planetary Science, and may help astronomers predict how common water is on other planets.
