Some cosmic impacts are loud, fiery, and leave unmistakable craters. Others are quieter in geological terms, yet no less destructive. These “touchdown airbursts” occur when a comet or asteroid ...

Did mammoths, sabre-tooth tigers and other Ice Age megafauna face a similar, impact-induced fate to the dinosaurs? That’s ...

For most of human history, the story of cosmic catastrophe has been told in craters: scars like Chicxulub that mark where asteroids slammed into the planet and rewrote the rules of life. A growing ...

(Santa Barbara, Calif.) — Touchdown airbursts — a type of cosmic impact that may be more common than the crater-forming, dinosaur-killing kind — remain somewhat less understood. UC Santa Barbara Earth ...

Earth’s surface bears the scars of obvious catastrophes, from dinosaur-killing craters to lava fields, but a growing body of research suggests a quieter class of cosmic assault has been largely ...

(Santa Barbara, Calif.) — Researchers continue to build on a body of evidence for a fragmented comet that is thought to have exploded over the Earth almost 13,000 years ago, which may have had a role ...

Shocked quartz, indicative of extreme pressure and temperature, was discovered at three prominent Clovis culture archaeological sites (Murray Springs, Blackwater Draw, Arlington Canyon). The presence ...
