Star Life Cycle Practice

Front

What is a black hole?

Back

A black hole is a stage in the life cycle of a high mass star where the gravitational pull is so strong that not even light can escape.

Front

What stage follows the main sequence for a low mass star?

Back

The stage that follows the main sequence for a low mass star is the Red Giant stage.

Front

What is a Main Sequence Star?

Back

A Main Sequence Star is a stable star that is in the main phase of its life cycle, like our sun.

What happens to a high mass star after it becomes a supernova?

Back

After a supernova, a high mass star can become a black hole or a neutron star.

Front

What is a Nebula?

Back

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

Front

What is the life cycle of a star?

Back

The life cycle of a star includes stages: Nebula, Main Sequence, Red Giant/Supergiant, and then either a white dwarf, neutron star, or black hole.

Front

What is a Red Giant?

Back

A Red Giant is a late stage in the life cycle of a star where it expands and cools after exhausting its hydrogen fuel.

Front

What is a white dwarf?

Back

A white dwarf is the remnant of a low to medium mass star that has exhausted its nuclear fuel and shed its outer layers.

Front

What is a supernova?

Back

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

What is the difference between a low mass star and a high mass star?

Back

Low mass stars have a mass less than about 8 times that of the sun, while high mass stars have a mass greater than that.
