1. The Life of a Massive Star
By: The Administrators of

2. Stage 1: Planetary Nebula
A planetary nebula is residual matter left behind when a star explodes. It compacts to form a protostar.

3. Stage 2: Protostar
A protostar is compacted matter of a planetary nebula and the second stage of a massive star.

4. Stage 3: Main Sequence
The main sequence is the process followed as a star goes from protostar to a “Red Giant” or “Super Giant”.

5. Stage 4: Red/Super Giant
Giant is an understatement for this huge star. It is achieved at the completion of main sequence and when it explodes: can lead to two outcomes.

6. Stage 5: Supernova
The Supernova stage occurs when a star explodes. From here, it either becomes a neutron star or a black hole.

7. Stage 6a and 6b
6a b
Black Hole Neutron Star

8. Stage 6a: Black Hole
A black hole can be found at the center of a galaxy. It occurs after a supernova and emits enough energy to hold an entire galaxy together.

9. Stage 6b: Neutron Star
A Neutron Star is a star with combined neutrons and electrons that create a tiny compact star.
