Astronomers Stress the Need for Characterizing the Population of Nearby Potential Earth-Impactors

by Dan Majaess October 14, 2013

The meteor explosion over Russia in February 2013 raised concerns that even small asteroid impactors may wreak some havoc given our heavily populated cities.  A new study by NASA scientists aims to improve our understanding of such asteroids that are lurking in Earth’s vicinity.  The team, led by Amy Mainzer, noted that only a mere […]

Citizen Scientists Hunt for Impact Craters in Persia

by Dan Majaess July 15, 2013

Citizen scientists have discovered planets beyond our Solar System and established morphological classifications for thousands of galaxies (e.g., the Planet Hunters and Galaxy Zoo projects).  At an upcoming meeting of planetary scientists, Hamed Pourkhorsandi from the University of Tehran will present his efforts to mobilize citizens to identify impact craters throughout Persia.   Pourkhorsandi said he is recruiting volunteers to identify […]
