Stars Quiz – The Life of Stars
Stars are giant balls of hot gas powered by nuclear fusion in their cores. They are born in nebulae when gravity pulls gas and dust together, and they spend most of their lives fusing hydrogen into helium.
A star's mass decides its fate. Sun-like stars swell into red giants and end as white dwarfs, while massive stars explode as supernovae, leaving neutron stars or black holes. Star colors reveal their temperatures, from cool red to hot blue.
Stars created most of the elements in our bodies, from carbon and oxygen to iron. When we look at the night sky, we see stars at different stages of life, some of whose light left them thousands of years ago.
