Bright teal lines separate the screen in half. Text. Myth versus Reality. Above the Myth side is a constellation map with a horned bull. On the Reality side is a bright, bursting light.
Myth. All stars end their lives in supernova explosions.
Reality. Relatively few stars end their lives as supernovae. Stars that are many times more massive than the Sun explode as supernovae. But stars like the Sun, which are much more common, can end their lives quietly by gently puffing away their outer layers.
