With climate change, over-exploitation of natural resources, and man-made ecological problems on this planet, we should stop and wonder – what can […]

I talk to Dr. Avi Loeb, chair of the astronomy department at Harvard, about the possibility that life may be much more common in the distant future around small, dim, and […]

Today, Dr. Dylan Spaulding, a project scientist at UC Davis in the Department of Earth and Planetary Science, talks with us about how he creates high velocity impacts in the lab with a canon, and what this can tell us about planet formation.
