Asteroid from Beyond Jupiter Caused Dinosaur Extinction, New Study Confirms
Key Points: The asteroid that caused the dinosaur extinction 66 million years ago originated beyond Jupiter. Geochemical evidence from the Chicxulub impact site supports the origin of this outer solar system. The study rules out the comet hypothesis, suggesting the impactor was a carbonaceous asteroid. The findings highlight significant events in the asteroid belt that may have increased Earth collisions. New geochemical evidence from the Chicxulub impact site in Mexico suggests that an asteroid that originally formed beyond Jupiter's orbit caused the catastrophic event that led to the extinction of nearly all dinosaurs 66 million years ago. The findings, published...
