Water makes up 71% of Earth's surface, but no one knows how or when it arrived on Earth.
Researchers analyzed melted meteorites that had been floating around in space since the solar system's formation 4 1/2 billion years ago.
They found that these meteorites had extremely low water content.
They were among the driest extraterrestrial materials ever measured.
Results could have implications for the search for water on other planets.
The research paper, "Degassing of early-formed planetesimals restricted water delivery to Earth," was published in Nature on March 15, 2023.
