Princeton Researchers Uncover Violent Origins of Geminids Meteor Shower.

Researchers at Princeton University have used data from NASA's Parker Solar Probe to deduce that a violent, catastrophic event, such as a high-speed collision or a gaseous explosion, likely created the Geminids meteoroid stream, which unusually originates from an asteroid rather than a comet. The Geminids meteoroids light up the sky as they race past Earth each winter, producing one of the most intense meteor showers in our night sky. The findings deepen our understanding of the composition and history of asteroids and narrow down hypotheses about this asteroid's composition and history that would explain its unconventional behavior.
