Question 4

Explain the life cycle of a star

Answer 4

-All stars begin as Nebulas. If big enough and starts spinning, collapses to form a star.
-size depends on how much stuff was in the nebula, can be broken into several categories.
Small/medium(dwarf): 10-20B, burn hydrogen to helium> Red giant, burns helium 1B> hydrogen + helium used up, star collapses to form white dwarf, few T
Large: Forms giant, 50B, burns hydrogen> Supergiant, 20B, burns helium> Supernova, massive explosion, 1 month+, shock waves cause damage (knock distant moons/planets out of orbit)+ start spinning nearby nebulas

Question 5

What stars are bigger than ours?

Answer 5
