There is Water on the Sun
This probably sounds crazy because the temperature of the “surface of the sun is around 6000 Kelvin.
It’s so high that molecules can not exist and even atoms exist in the form of ionized plasma. So how can water exist on Sun? Water exists on sunspots and at a distance of around 500 km from photosphere. Sun spots are the regions with lesser temperature than the rest of the surrounding photosphere.The water obviously exists as vapour. This sheds more light.
So how can there be water molecules on the sun? Well, there are a few cool places, just cool enough that some hydrogen (H) atoms and oxygen atoms (O) can team up to become a water molecule (H2O). Those are the centers of sunspots on the outside of the sun. Sunspots are dark places on the sun with a lot of magnetic field, much much stronger than the earth’s magnetic field which pushes your compass needle to the direction of the North pole. In sunspots, the magnetic field is so strong that it pushes the gas largely aside and makes it cool as well. The remaining gas is so cool that there can be a bit of water by H atoms joining O atoms. That is still water vapor, not fluid! You can’t go surfing on the sun – and I can’t go kayaking there (that’s my sport).There is more to this. When the universe started in what we think was a big explosion called the Big Bang, it made only hydrogen and helium, not all the other elements. Those were made later, inside stars and when heavy stars exploded at the end of their life. All the atoms other than hydrogen and helium around us and inside us (yes, you too) were made in stars long before our sun and our planet were formed. You are made of star stuff! In five billion years from now, the sun will die but not explode, it is too small for that. But it will swell up first and push the earth out of the way. It may happen that the H and O atoms making up the water in your body right now end up in some other living body say ten or more billion years from now.
Did you know:
The sun travels at a speed of 220 kilometers every one second? Well, that’s incredibly fast! However, even with that kind of speed, it can complete one revolution around the galactic core (the central point of our Milky Way galaxy) in a staggering 250 million years! The distance of the sun from the galactic core is 25,000 light years. Did you know that sun is our solar system’s largest mass accounting for 99.8% of the total mass? Jupiter takes up the remaining mass and the remaining planets and galactic bodies in our solar system together form only a fraction of the total mass of our solar system!
How Much Water Would Extinguish the Sun?
The Sun isn’t on fire. There’s no amount of water you could add that would quench it, you’d just make it explode, but if you used firehoses that could spray water at nearly the speed of light, you could probably shut the thing off and eventually freeze us all, which is what I think you were hoping for in the first place.
