“This is an excellent podcast for anyone interested in, or concerned about, asteroids, comets and the impact threat. Hosted by Dr. Al Grauer, one of the astronomers working in Near Earth Object detection, each episode reports on some aspect related to the rocks that are our fellow cosmic travelers as well as our biggest threats. Highly recommended, very informative.”
