Life Cycle of a Star

Front

What is a supernova?

Back

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

Front

What is a protostar?

Back

A protostar is formed when a nebula collapses under its own gravity and becomes hot enough to initiate nuclear fusion.

Front

How are elements heavier than iron produced in stars?

Back

Elements heavier than iron are produced during a supernova explosion.

Front

Which of the following is NOT a final stage of a star?

Back

Red giant is not a final stage of a star; it is a phase in a star's life cycle.

Front

Which type of star burns fuel the slowest?

Back

Red Dwarfs burn fuel much slower than other types of stars, allowing them to stay on the main sequence the longest.

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 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 is a black dwarf?

Back

A black dwarf is a theoretical stellar remnant that occurs when a white dwarf has cooled sufficiently that it no longer emits significant heat or light.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process by which two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What is a red giant?

Back

A red giant is a late stage in the life cycle of a star, characterized by expansion and cooling after hydrogen in the core is depleted.
