Astronomers have discovered a white dwarf star that has 99.9 percent pure oxygen atmosphere.
The presence of an ancient sun that is able to live for so long, causing its outermost layer to consist of only pure oxygen, was just a theory before the white dwarf star was discovered.
Astronomers Spot White Dwarf Star With 99.9 Percent Pure Oxygen Atmosphere
And people think that we know enough to stop looking. God I love this stuff! Always something new out there to learn.
....someone light a match and see what happens.
Interesting. How it formed is the interesting part, normally when white dwarfs undergo conversion to Oxygen, it happens very quickly, and produces enough energy to blow the star up.
That would not produce any substantial effect.
A small hydrogen bomb might produce a considerable effect.
That's still be negligible.
Now thinking about that, it is negligible, one day we will be capable of anti-matter bombs, and will destroy stars for our enjoyment on national holovision. That is of course, if we don't wipe ourselves out first. It is amazing to see a star like this though.
To light off this star you would need to provide burning material. A small gas giant might not burn up all the oxygen in this atmosphere.
We aught to find a way to harvest the pure O2.

This oxygen is hot degenerate plasma. It would incinerate any planet we tried to terraform with it.
You cool it first as you harvest it.
Now we just need one full of nitrogen.
...and some H2 for fuel.
This would be a nice reserve for putting an atmosphere on every 1g rock we come across.
The energy required to get this oxygen is more than you realize, its a white dwarf and is so compact that a spoonful weighs tons. The amount of energy required to overcome that gravity ...

Well think about it for a little while and your project of space lifting fresh water will not seem so insurmountable.

A ludicrous amount of energy would be required to destroy a star.
Quick calculation says at minimum of about 2.2*10^41 joules to accelerate our sun's mass to escape velocity. Now, this wouldn't be entertaining at all: at this scale escape velocity isn't even readily visible. Observers would have to watch for hours before they noticed much a difference in the sun's radius.
2.4*10^24 kg of antimatter is required to generate this kind of energy, which is in the range of the entire earth's mass converted into antimatter.
And our sun ain't even big.

so we can breathe there
so we can breathe there
No, we can only breathe molecular Oxygen at pressures within a few orders of magnitude of atmospheric. This is neither.
