Bright Meteor // Dark Matter

Russian Meteor (starts at 4:28) Just a few days ago on February 15th,  a large meteor broke up in the skies over Russia, creating an air blast and sonic boom, which caused damage to buildings that injured over 1,000 people. We talk with Dr. Clark Chapman to ask why the universe is taking potshots at us.  Dr. Chapman is an astronomer and Senior Scientist at the Boulder office of the Southwest Research Institute, and is recognized as a leading researcher in planetary cratering and in the physical properties asteroids, comets, and moons.  For more than a decade Dr. Chapman has been studying the risks of comets and asteroids hitting the Earth and has been a member of Congressional and international committees regarding impact hazards. He is a founding member of the B612 Foundation, which is developing ways to detect and deflect hazardous asteroids.

Dark Matter (starts at 12:45) Maybe you’ve heard about it.  Maybe you even know that it is everywhere throughout the universe.  But for such a ubiquitous material, what do you really know about Dark Matter?  If the answer is “Not much,” don’t worry, you are in good company; many scientists would say the same thing. But, you’re in luck because we have Dr. Martin Huber with us today talk about Dark Matter – what is known know about it and how we can detect it.  Dr. Huber is Professor of Physics and Director of the Master of Integrated Sciences program at the University of Colorado, Denver.  He is a member of the Cryogenic Dark Matter Search project, and on today’s show he sheds some light on Dark Matter.
