Bright teal lines separate the screen in half. Title. Myth versus Reality. Above the Myth side is a constellation map with a horned bull. On the Reality side is a bright bursting light.
Text. Myth. Supernovae pose a threat to life on Earth.
Reality. Most supernovae are far too far from the Earth to have any effect on us. If a star should explode relatively close to us, closer than roughly 100 light-years away, it could damage Earth's ozone layer and shower us with X-rays, gamma rays, and energetic particles. Fortunately, there is no star within 100 light-years that is likely to explode any time soon.
