Life cycle of a star

Front

What is a Stellar Nebula?

Back

A Stellar Nebula is a large cloud of gas and dust in space, where new stars are formed.

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.

Front

What is the final stage of a very high mass star?

Back

The final stage of a very high mass star is a Black Hole.

Front

What characterizes the main sequence stage of a star?

Back

The main sequence stage is characterized by stable nuclear fusion of hydrogen into helium.

Front

What is the first stage in the life cycle of a star?

Back

The first stage in the life cycle of a star is the protostar stage.

Front

What happens during the protostar stage?

Back

During the protostar stage, gas and dust collapse under gravity to form a dense core that will eventually become a star.

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.

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 the difference between a Red Giant and a White Dwarf?

Back

A Red Giant is a late stage in the life of a star where it expands and cools, while a White Dwarf is the hot, dense remnant left after a star has shed its outer layers.

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, and is the process that powers stars.
