Answer 1

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.
