Answer: Here we go
Step-by-step explanation:
Step 1- A cloud of gas and dust collapses due to gravity, creating a protostar
Step 2- Gravitational energy powers the young star until nuclear fusion occurs. The star may live millions or billions of years.
Step 3- The star expands into a red giant.
Step 4- The star expands, cools, and loses mass over time.
Step 5- A supernova explosion occurs. Most of the star is blown away.
Step 6- Depending on how big the star once was, either a black hole of neutron star is formed.
Step 7- The exploded star joins new gas clouds, and new star are formed.
