Question

a supergaint is when
the star explodes
expands and cools and creates carbon
collapse on itself
expands and sheds in layers multiple times going through multiple elemental changes
when a massive star burns through all its fuel source what is the next stage
pulsar
neutron star
white dwarf
supernova
massive stars go through supernovas because
there is way to much gravity pulling inward it cannot rebound and explode so it just takes in everything in its path including light
the gravity is pulling all those layers inward and when it hits the core it essentially explodes

Explanation:

• First Question: A supernova is when a star explodes. This is a well - known astronomical event.
• Second Question: When a massive star burns through all its fuel, the next stage is a supernova. After the supernova, depending on the mass, it can form a neutron star or a black hole, but the immediate next stage is the supernova explosion.
• Third Question: Massive stars go through supernovas because the gravity is pulling all those layers inward and when it hits the core it essentially explodes. The core collapse leads to a shock wave that causes the outer layers to be ejected in a supernova.

Answer:

1. The star explodes
2. Supernova
3. The gravity is pulling all those layers inward and when it hits the core it essentially explodes
