The chemical composition of a meteorite could shake up scientists' understanding of how Earth got its water.
Researchers found signs of hydrogen sulfide in a type of meteorite similar to those that made up the early Earth. If these rocky bodies contain abundant hydrogen when out in space, it's possible that Earth could have formed with the materials to make water, rather than getting most of its water from chance collisions with asteroids and meteoroids throughout the planet’s early history. The findings were published April 16 in the journal Icarus.
