Life Cycle of a Star

Front

What is the Main Sequence stage in a star's life cycle?

Back

The Main Sequence is the stage where a star spends most of its life, fusing hydrogen into helium in its core, and is characterized by a stable balance between gravitational collapse and nuclear fusion.

What happens to a high mass star after it explodes in a Supernova?

Back

After a Supernova, a high mass star that is not heavy enough to become a black hole will turn into a Neutron Star.

Front

What is a Black Hole?

Back

A Black Hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Where does a star begin its life?

Back

A star begins its life in a Nebula, which is a cloud of gas and dust.

Front

What is a Nebula?

Back

A Nebula is a large cloud of gas and dust in space, often the birthplace of stars.

Front

What is a Red Giant?

Back

A Red Giant is a late stage in a star's life cycle where it expands and cools after exhausting the hydrogen in its core.

Front

What is a White Dwarf?

Back

A White Dwarf is the remnant core of a star that has exhausted its nuclear fuel and shed its outer layers, typically very hot and dense.

What is a Supernova?

Back

A Supernova is a powerful and luminous explosion that occurs at the end of a star's life cycle, often resulting in the formation of a Neutron Star or Black Hole.

Front

What is a Neutron Star?

Back

A Neutron Star is the collapsed core of a massive star that has undergone a Supernova, composed almost entirely of neutrons.
