=**__The Lifecycle of a star__**=

A Nebula is a large cloud of gas and dust spread out in an immense volume.

A Protostar is a contracting cloud of gas and dust with enough mass to form a star. It is the earliest stage in a stars life.

A star is a massive, luminous sphere of plasma held together by gravity.

When a low-mass star runs out of fuel, it's core shrinks and outer portion expands, becoming a Red Giant.

When a high-mass star runs out of fuel, it's core shrinks and outer portion expands, becoming a Supergiant.

When a Red Giant runs out of fuel, it does not explode, but instead slowly drifts apart, becoming a Planetary Nebula.

A Supernova is a sudden, massive explosion of when a Supergiant runs out of fuel.

The cool, blue-white core of a low-mass star thats left behind.

When a White Dwarf eventually stops glowing, it becomes a Black Dwarf.

Neutron Stars are the remains of high-mass stars. They are even smaller and denser than White Dwarfs.

An object with gravity so strong, that nothing, not even light, can escape from it. They are made from the remnants of Supernovas.
