Giant Baptistina Asteroid Not Guilty of Killing Dinosaurs

But another one most certainly is.

NASA has determined that the asteroid that was believed to have killed off the dinosaurs isn't guilty of the crime, meaning the culprit for the planet's biggest mass extinction (so far) remains unknown. While astronomers agree that the extinction was caused by an asteroid, they've now ruled out the massive Baptistina asteroid as the cause. Since 2007, researchers had figured that Baptistina had smashed into the asteroid belt between Mars and Jupiter some 160 million years ago and broke up into smaller fragments, one of which smacked into the Earth some 65 million years ago. But NASA's infrared WISE telescope has placed the age of Baptistina's remnants as 80 million years old, meaning they're too young to have travelled from the asteroid belt to Earth in time to kill the dinosaurs. NASA researchers are now trying to determine what other asteroid could be responsible for the dinocide. One hopes we can go all Armageddon on the new culprit and blow it to heck with nukes. Gotta nuke something, right?
