Life Cycle of Stars

Front

What is the life cycle of a star?

Back

The life cycle of a star is the series of stages a star goes through from its formation in a nebula to its end state, which can be a white dwarf, neutron star, or black hole.

What is a nebula?

Back

A nebula is a large cloud of dust and gas in space, where stars are born.

Front

What element is fused in a star to form a Red Giant?

Back

Helium is fused in a star to form a Red Giant after it runs out of hydrogen.

Front

What is a supernova?

Back

A supernova is a powerful explosion that occurs at the end of a star's life cycle, often leading to the formation of a neutron star or black hole.

Front

What are red supergiants?

Back

Red supergiants are the largest and most massive stars in the universe, known for their size and brightness.

Front

What is the heaviest element that can be created inside a star?

Back

Iron is the heaviest element that can be created inside a star during its life cycle.

Front

What happens to a star after it becomes a red giant?

Back

After becoming a red giant, a star may shed its outer layers and form a planetary nebula, leaving behind a core that can become a white dwarf.

Front

What is a neutron star?

Back

A neutron star is the remnant core of a massive star that has undergone a supernova explosion, composed mostly of neutrons.

Front

What leads to the formation of black holes?

Back

The formation of black holes is directly caused by the collapse of a massive star after a supernova.

Front

What is the difference between a white dwarf and a neutron star?

Back

A white dwarf is the remnant of a low to medium mass star, while a neutron star is the remnant of a massive star after a supernova.
