New study suggests water came to early Earth via comets
Comets probably delivered Earth its water billions of years ago, new study reveals
Water. All life on Earth requires it in some way or another, and it's hard to miss that roughly 70% of our planet's surface is covered in the stuff. Thus, understanding where Earth's water came from is a very important part of understanding life's origins, and researchers were pretty sure they knew how it got here — up until 2014.
Comets may have delivered water to Earth
Recent studies show comet dust influenced earlier measurements of water’s origins on Earth, challenging previous findings.
Ancient comet collisions could have brought water to Earth, NASA says
“A wave of comet and asteroid collisions with the solar system’s inner planets 4 billion years ago would have made this possible.,” a portion of the report read. Adding, that while water likely existed on Earth 4.6 billion years ago, much of the water would have vaporized because the Earth formed close to the sun with intense heat.
Comets probably delivered Earth its water long ago, new study reveals
The connection between those icy comets — which are called Jupiter-family comets because their orbits are affected by Jupiter's gravitational influence — and Earth's water res
