“About 66 million years ago, it’s believed, the dinosaurs were wiped out in part by the impact of a 10-kilometer-wide asteroid, killing most land-based life in a matter of hours as molten debris rained down. The impact also blanketed our planet in dust and soot, blocking out the light of the sun and causing a decades-long winter.” So when is the next one hitting? According to a new study, we’ve got some breathing room. Earth is probably safe from a killer asteroid for 1,000 years. (They said the same thing about debt ceiling negotiations.)
