Study Rebuts Hypothesis That Comet Attacks Ended 13,000-Year-Old Clovis Culture

Rebutting a speculative hypothesis that comet explosions changed Earth’s climate sufficiently to end the Clovis culture in North America about 13,000 years ago, Sandia lead author Mark Boslough (Discrete Mathematics & Complex Systems Dept.) and researchers from 14 academic institutions assert that other explanations must be found for the apparent disappearance. “There’s no plausible mechanism to [...]

NASA Earth at Night Video

Have you ever wondered what the Earth looks like at night? NASA provides a clear, cloud-free view of the Earth at night using the Suomi National Polar-orbiting Partnership Satellite. The satellite utilizes an instrument known as the Visible Infrared Radiometer Suite (VIIRS), which allows the satellite to capture images of a "remarkably detailed view of [...]

The Rush to Exploit an Increasingly Ice-Free Arctic

The U.S. Coast Guard icebreaker Healy. It’s that time of year again, when we check in to see where the annual Arctic sea ice minimum will end up. We haven’t quite bottomed out at the end of the melt season, yet, but already 2012 has set new records for smallest Arctic sea ice extent and [...]

Water Not So “Squishy” Under Pressure

When squeezed to pressures and temperatures like those inside giant planets, water molecules are less squeezable than anticipated, defying a set of decades-old equations used to describe watery behavior over a range of conditions. Studying how molecules behave in such environments will help scientists better understand the formation and composition of ice giants [...]
