I read the article New Evidence suggests the sun will not become a Planetary Nebula..
1) What was the prior belief regarding the sun's life cycle?
The prior belief regarding the sun starts from a Stellar Nebula, than a average star, then in 5 billion years a Red Giant, then a planetary Nebula, and finally a white dwarf.
2) What does the new evidence suggest?
The new evidence says that the stellar object must be at least 20% heavier than the sun for it to form a planetary Nebula.. However, before this theory it was believed that stars are 1 solar mass ;which is about the size of the sun; to form planetary nebula.. Aside from that, the new research says that it suggests that most planetary nebulae stem form binary system. That means that without a companion the sun may not exceed the mass limit needed to generate the nebula.
3) What impact does this evidence have on our understanding of the sun's future?
From this we don't know what will happen to our sun's future. Further research in Binary systems is needed in order for scientist to make their hypothesis more accurate.
4) Explain the relationship between gravity and fusion that keeps our sun in its current state.
The gravitational push keeps the sun in its current state; if there wasn't gravitational push towards it the sun would've exploded.
5) What do you find most fascinating about solar science?
I find solar science quiet fascinating; my favorite thing is learning about how our sun might be in 5 billion years and the new theories that support our sun.
