Stellar Evolution
Stellar evolution is the life cycle of stars. Stars are born, live, and die.
Protostar Formation
A protostar forms from a collapsing gas cloud. Gravity pulls in, and the core heats up.
Main Sequence
The star fuses hydrogen into helium. This is the longest stage of a star’s life.
Red Giant
As hydrogen fuel runs out, the star expands. It becomes a red giant, fusing helium into heavier elements.
White Dwarf
The star sheds its outer layers. A white dwarf remains, slowly cooling over time.
Supernovae
Massive stars explode as supernovae. This explosion is incredibly powerful.
Neutron Stars and Black Holes
The core collapses into a neutron star or black hole. These objects are extremely dense.
Conclusion
Stellar evolution shapes the universe. Stars create heavy elements and influence their surroundings.
