Supernovae are when very massive stars finally come to the end of their life. They are important events as during the very short period in which the explosion occurs, temperatures and pressures are sufficient to fuse atoms, making heavier elements. Any elements with a nucleus heavier than the iron nucleus would have had to be formed during a supernova explosion.

How does the existence of organisms in hot springs relate to the scientific hypothesis of how life forms arose on earth?
That's a bit of a nonsense question. The existence of life is consistent with *any* and *every* hypothesis that tries to explain the existence of life, scientific or not. The existence of life is the very thing that the hypothesis is trying to explain, so necessarily the hypothesis assumes it and must therefore be consistent with it. The same goes for the *kind* of life we find on Earth: since any scientific hypothesis must explain the life we find here, such a hypothesis must necessarily be consistent with the life we find.
