Did Earth’s oceans originate from an ancient near-Earth asteroid? Scientists find clues
A new study reveals that asteroid Ryugu once had liquid water. This challenges old beliefs about asteroids. Scientists analysed rock fragments from Ryugu. They found water movement signs occurring long after Ryugu formed. A massive impact may have melted ice. This allowed water to flow through the rocks. Asteroids may have delivered more water to early Earth.
