Yet more astronomy news cut and pasted to the physics group instead
of an astronomy group.

Why was oxygen unexpected when comets contain a lot of H2O?

Do these guys know what the 'O' in H2O stands for?

How does free oxygen around a comet "challenge theories about the formation
of the Solar System"?

What other chemicals would there be in a vacuum around an object that
has a lot of ice that would react with oxygen?

A cloud of water being bombarded by high energy partiles in a vacuum
and oxygen was found; what did they expect, rubbidium?

Because it hasn't reacted with other elements, most notably hydrogen, of 
which there's an abundance.

See above.

Those high-energy particles are pretty tenuous, not enough to dissociate 
the observed quantity of oxygen from water.

Do you know much astronomy, Jim?  Lots of physics involved in it, makes it 
pretty interesting even after one tires of watching eclipses and meteor 
showers.

Cosmology even more so.  It's as much fun as one can have with his pants 
on.

Time is on the side of those "tenuous" particles.

Baking cupcakes involves physics, yet most rational people would not
post cupcake recipes to a physics group.

I had the misfortune to take two semesters of astronomy from a guy
who was just as big an ass as the ass hat.

It should be obvious to you by now no one thinks your crap cut and
pastes are worth discussing, shit head.

OK, things are starting to make sense.  Not everything that's logical is 
necessarily also rational....
