Flashcard HR Diagram and Star Life Cycle

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where hydrogen atoms combine to form helium, releasing energy, typically occurring in stars.

Front

What stage is our sun currently in?

Back

Our sun is currently in the Main Sequence stage of its life cycle.

Front

What are the largest stars called?

Back

The largest stars are called Supergiants.

Front

What is the Main Sequence in a star's life cycle?

Back

The Main Sequence is the longest stage of a star's life cycle, where it spends most of its time fusing hydrogen into helium.

Front

True or False: Stars are really close together in outer space.

Back

False. Stars are very far apart in outer space.

Front

What is a Protostar?

Back

A Protostar is an early stage in the formation of a star, where gas and dust begin to collapse under gravity.

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 happens during a supernova?

Back

A supernova is a powerful explosion that occurs at the end of a star's life cycle, often resulting in the star's destruction.

Front

What is a Red Giant?

Back

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

Front

What is a Dwarf Star?

Back

A Dwarf Star is a small star, often at the end of its life cycle, such as a white dwarf.
