Although invisible to the human eye, some cameras can spy these high-altitude light shows. The radiation can be bright enough to see from hundreds of miles away in outer space. And scientists have now uncovered new data on the source and frequency of this unusual phenomenon.  Read more…

Volcanic activity began in what is now India prior to the collision. It then continued on, long after the impact, the new study finds. Those eruptions may have spoiled the climate for dinos and other forms of life, the team of scientists now argues. Read more…

What Happens When You’re Caught in an Avalanche. World Science Festival.

Snow can be majestic and ethereal, but in the right combination of circumstances, it can prove deadly. Recently, two U.S. ski team prospects perished in an avalanche in the Austrian Alps; in the U.S., an average of 28 people die in avalanches every year,according to the Colorado Avalanche Information Center. Understanding how avalanches are triggered, and how they flow, can suggest new safety procedures and other precautions that could provide some measure of protection on the slopes. Read more…
