Travelers in the Night Eps. 875 & 876: Newly Discovered Crater & Neighborhood Traffic

About this episode

Dr. Al Grauer discusses newly discovered crater evidence and recent asteroid tracking efforts.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org From November 2025. Today's 2 topics: - Dr. Uisdean Nicholson from Heriot-Watt University and his team of 9 co-authors analyze 3D seismic imaging and drill cuttings from a 1980s oil well to make a convincing case that the Silverpit crater was produced by a the impact of a 1.5 football field diameter asteroid approximately 45 million years ago. - In a recent 60 day period asteroid hunters tracked 24 space rocks which came closer than our Moon. My team the University of Arizona's Catalina Sky Survey operates 5 telescopes in the mountains around Tucson, Arizona. Our goal is to find objects like 2025 RM1 which are on an impact trajectory with our home planet in advance so that people in the effected area can be warned to stay away from doors and windows.
