The Life Cycle of Stars-B

Front

What is a nebula?

Back

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

Front

What is a protostar?

Back

A protostar is the initial stage of a star's formation, occurring after a nebula collapses.

Front

What happens during the main sequence phase of a star?

Back

During the main sequence phase, a star fuses hydrogen into helium in its core, producing energy.

Front

What is a red giant?

Back

A red giant is a late stage in the life cycle of a low mass star, where it expands and cools after exhausting hydrogen in its 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, often resulting in the formation of a neutron star or black hole.

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 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 parallax?

Back

Parallax is the apparent shift in position of a nearby star against distant background stars, used to measure distances in space.

Front

What is the life cycle of a low mass star?

Back

The life cycle of a low mass star includes stages: nebula, protostar, main sequence, red giant, and finally a white dwarf.

Front

What is the life cycle of a massive star?

Back

The life cycle of a massive star includes stages: nebula, protostar, main sequence, red supergiant, supernova, and then either a neutron star or black hole.
