Life Cycle of a Star

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 eventual death, which can result in a white dwarf, neutron star, or black hole.

What is a nebula?

Back

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

Front

What is a protostar?

Back

A protostar is an early stage in the formation of a star, where the nebula collapses under its own gravity and begins to heat up.

Front

What is a main sequence star?

Back

A main sequence star is a stable phase in a star's life cycle where it fuses hydrogen into helium in its core.

Front

What are red dwarfs?

Back

Red dwarfs are small, cool stars that burn their fuel slowly and can remain on the main sequence for billions of years.

Front

What is a supernova?

Back

A supernova is a powerful explosion that occurs at the end of a massive star's life cycle, resulting in the star's death.

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.

Front

What happens to a red giant's core?

Back

The core of a red giant collapses and can become a white dwarf, neutron star, or black hole, depending on the mass.

Front

What is a white dwarf?

Back

A white dwarf is the remnant of a star that has exhausted its nuclear fuel and shed its outer layers, leaving behind a hot, dense core.

Front

What is a blue giant?

Back

A blue giant is a very hot, massive star that burns its fuel quickly and has a short life span compared to smaller stars.
