3-SECOND FLASH

Stars are cosmic generators – 200 billion of them in a typical galaxy like the Milky Way make the light and most of the heavy elements that fill our universe.

3-MINUTE EXPANSION

A star’s mass determines almost everything about it. Our Sun is a relatively modest-mass star so it glows yellow hot, has enough hydrogen to last 10 billion years and will end as a white dwarf. A star a tenth of the mass of the Sun will be dim and red and live for hundreds of billions of years, while one ten times more massive will glow white hot and burn hydrogen so rapidly that it will last less than 100 million years and then explode as a violent supernova.
