Trojan Asteroid 2019 LD2. Credit: NASA, ESA, STScI, B. Bolin IPAC/Caltech) Comet Comes in from the Cold and Finds an Off-Ramp on Its Sunward Journey Long road trips can be tedious and boring. That’s why many road travelers break up their arduous journey by making rest stops along the way. […]

Artist’s rendering of a comet headed towards Earth. New theory explains possible origin of the Armageddon-causing object. It forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s known, left behind a crater off the coast of Mexico that spans 93 miles […]

A comet plunging through Earth’s atmosphere. It was tens of miles wide and forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s known, left behind a crater off the coast of Mexico that spans 93 miles and goes 12 miles deep. […]
