Half of Earth's water formed before the sun was born

Ice that formed in the interstellar cloud that gave birth to the sun survived that process to fill our oceans.

Good news for hunters of extraterrestrial life: Water may be more widespread in planetary systems than previously thought. A team of researchers studying the origin of the water in our solar system has concluded that up to half of it formed before the sun itself was born—that is, in the cloud of dust and gas that was the progenitor of our solar system. If water can form in abundance in such clouds, then it may be found everywhere.
