Does anyone else believe Iron can extinguish a star

Um... well, it's not like a drop of iron is going to kill a star. What happens is, very massive stars begin producing iron in their cores - and that's the *heaviest* element that can be produced through fusion while releasing energy.

Once iron begins to be produced, the star is getting ready to die. Without a constant fusion reaction occurring, the star can't fight it's own immense mass, and it will suddenly collapse - falling in on itself, and creating a supernova - a *huge* explosion - producing possibly a neutron star or even a black hole.

Ullysses won't affect our sun at all...

It's not the iron that extinguishes a star, it's having nothing left to fuse except iron or something heavier because starting with iron, you don't get enough energy from fusion.

I'll think I'll pass on your twitter, it seems like you have nothing intelligent to say.

The fusion of iron in a star requires more energy than a star is capable of *normally* generating. Thus fusion in the star stops. The next step is for the entire mass of the star to collapse under its own gravity, then rebound off its core in a supernova explosion.

Iron won't really extinguish a star it will make it colapse and then it will explode. Not really extinguishing the star.

I'm totally going to follow you on Twitter. I cannot promise I won't constantly harass you.

no, it would take an immeasurable amount of iron.... however, most stars keep on fusing well past iron and into much heavier metals.

Blah blah blah You are no Ron Hubbard that's for sure. Good luck with your cult though.

No. No sane educated person could believe such crap. Iron is formed in stars........it can't extinguish them. If it could then every star in the universe would have been extinguished long ago. Iron is the heaviest element that can be fused in the core of a star. Any heavier elements require more energy to create. These are formed during supernovae.

Your "question" is quite confusing though. Are you implying that the tiny little Ulysses probe that was launched back in the 1980's is somehow going to extinguish the Sun? Never mind that very, very, very little iron is used in any air or space craft (iron is heavy), what about all the plutonium it's carrying in its nuclear generators? Plutonium isn't a big deal but a little iron is? Countless asteroids with a LOT more iron in them than a million Ulysses probes have crashed into the Sun in the past few billion years.
