What is the life cycle of a star?

Back

The life cycle of a star refers to the series of stages a star goes through from its formation in a stellar nebula to its eventual death, which can result in a white dwarf, neutron star, or black hole, depending on its mass.

What is a Stellar Nebula?

Back

A Stellar Nebula is a cosmic cloud of dust and gas that serves as the birthplace of stars. It is the first stage in the life cycle of a star.

What happens during the Red Giant phase of a low-medium mass star?

Back

During the Red Giant phase, a low-medium mass star expands and cools after exhausting hydrogen in its core, leading to the fusion of helium and other heavier elements.

Front

What is a White Dwarf?

Back

A White Dwarf is the remnant core of a low-medium mass star that remains after it has shed its outer layers. It no longer undergoes nuclear fusion.

Front

What is a Planetary Nebula?

Back

A Planetary Nebula is formed when a red giant star expels its outer layers into space, creating a glowing shell of gas around the remaining core.

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 outer layers being ejected into space.

Front

What is a Neutron Star?

Back

A Neutron Star is the dense remnant of a massive star that has undergone a supernova explosion, composed mostly of neutrons.

Front

What is a Black Hole?

Back

A Black Hole is a region in space with a gravitational pull so strong that nothing, not even light, can escape from it. It is formed from the remnants of a very high mass star after a supernova.

Front

What triggers the formation of a Black Hole?

Back

The formation of a Black Hole is triggered by the gravitational collapse of a massive star after it has exhausted its nuclear fuel and undergone a supernova.

Front

What is the final stage of a low mass star?

Back

The final stage of a low mass star is a White Dwarf.
