Water may be naturally occurring on all rocky planets

6 November 2020 Researchers present wild theory: Water may be naturally occurring on all rocky planets
Life is deeply dependent on water, but where does water come from? Based on new research, researchers from the University of Copenhagen believe it may emerge in connection with the formation of planets.

“There are two hypotheses about the emergence of water. One is that it arrives on planets by accident, when asteroids containing water collide with the planet in question,” says Professor Martin Bizzarro from the Centre for Star and Planet Formation at the Faculty of Health and Medical Sciences, University of Copenhagen.

Together with Assistant Professor Zhengbin Deng he has headed a new study that turns the theory about the emergence of water upside down.

“The other hypothesis is that water emerges in connection with the formation of the planet. Our study suggests that this hypothesis is correct, and if that is true, it is extremely exciting, because it means that the presence of water is a bioproduct of the planet formation process,” Martin Bizzarro explains.

If Martin Bizzarro and Zhengbin Deng’s theory proves correct, life in planetary systems may have had better chances of developing than previously assumed.

So, how would that change the solar system generation tables?

I don't think it would change it at all. The sysgen tables are based on observable planets and known values (like the habitable water zone). It really isn't detailed enough for the minute details on HOW that happens to make a difference.

I was wondering and decided asking would be better than merely continuing to wonder.

It does make for some interesting thoughts on the details though. I imagine that you'd more likely have water deep under the ground if it's naturally occurring, as opposed to just being on the surface from comets hitting the surface. That and if it's naturally occurring, it's easier to imagine worlds with a lot of water. You'd have to wonder how many millions of comets would have to hit a planet to create the Pacific Ocean...
