Water-worlds are common: Exoplanets may contain vast amounts of water

"The model indicates that those exoplanets which have a radius of around x1.5 Earth radius tend to be rocky planets (of typically x5 the mass of the Earth), while those with a radius of x2.5 Earth radius (with a mass around x10 that of the Earth) are probably water worlds."

Question to anyone...

What was the astro-mechanism that created so much water?

I presume star death is the mechanism that creates elemental Oxygen.

What is the process that combines two Hydrogen atoms with Oxygen?

[LibWhacker]

Oxygen is created in stars and dispersed in supernova explosions. It then mixes with hydrogen in clouds of dust and gas out in space and forms water. (Had to look it up :)

Re: “It then mixes with hydrogen in clouds of dust and gas out in space and forms water.”

There needs to be an energy source for fusion.

I can’t figure out where the energy comes from.

From inside the planets when they form?

From super heated gases caused by star death?

Splish, splash, I wuz takin’ a bath...

Just about every element on the Periodic Table is created in stars. The iron in our blood for instance.

Here is where water is, the oceans of the earth.. Don’t fall for this water Schlick on Mars crap. It it all a scam to get your money to pay “scientists” . There is nothing out there but vacuum!! And rocks!!

Water is a molecule, made by chemistry, not the product of nuclear fusion.

...and monkeys are likely to fly outta my butt.

Its a common occurrence.

Good question. Electrostatic attraction.

[jpsb]

Oxygen is the third most common element in the universe. So there is a lot of oxygen out there. Fusion in stars creates oxygen. Creating oxygen happens shortly before a star goes supernova.

A simple chemical reaction is all that is needed to combine hydrogen and oxygen into water.

[Technocrat]

H + H + O is exothermic, so if you have hydrogen and oxygen just hanging out around each other they with tend to combine, sometimes with great vigor :)
