Life Cycle of a Star

Life Cycle of a star

Stellar Nebula

the stellar nebula is a giant cloud of gas and dust in space. The Dust and gas come together and create knots. These knots eventually collapse with gravity, and pressure causes the core to heat up and create a protostar.

Massive Star

Average Star

Average Star

These stars generate energy from the fusion of hydrogen to helium, then helium to carbon. They could live up to 50 million-20 billion years.

Red GIant

• The outward pressure of fusion inside main sequence stars balances out the inward pressure of gravity which raises the core tempature.
• The helium core contracts and releases temperature, causing a spike of energy.
• The star continues to rise in temperatres until the helium runs out and fusion stops.

Planetary Nebula

Bright gas expelled from dying stars.

WHite Dwarf

When a star runs out of full, it collapses into itself, creating a white dwarf. The atoms continue to collapse into eachother until fade away.

Massive Star

Made up of hydrogen and helium, they are pretty big.

Red Supergiant

1. Has the largest radius of all known stars
2. Forms when massive stars use up all of their supply of hyrdogen,
3. Burns all the helium in their core

Supernova

Huge explosions in space. Happens when a massive star can no longer fuse the iron in it's core. Gravity stars to pull everything into the core which begins the rapid collapse of the star.

What is left of the supernova explosion, the collapsed core of the massive star.

Black HOle

Anything left of the massive star becomes squashed and is compacted in a very small object.
