A mainstay of the December night sky, the Geminids meteor shower first appeared in the mid-1800s, and it’s grown more impressive in the ensuing years. It now features up to 120 meteorites an hour given clear skies.
A new study may have found that the shower originated in some type of catastrophic collision. This differentiates it from most showers, which come from icy comets that pass close to the sun, that then melts and releases particles.
