What is a nebula?

Back

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

Front

What happens to a star during the red giant phase?

Back

During the red giant phase, a star expands and cools after exhausting hydrogen in its core.

Front

What is a planetary nebula?

Back

A planetary nebula is a shell of gas ejected from a star during the late stages of its evolution, often surrounding a white dwarf.
