Travelers in the Night Eps. 883 & 884: Theia & Turkeys and Asteroids
Description
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 January 2026.
Today's 2 topics:
- In the distant past things in our solar system were very much more wild and violent than they are today. 4.5 billion years ago a Mars sized object called Theia impacted Earth producing our Moon. Scientists are able research this event using the current chemical compositions of the Earth and Moon.
- Since in its early history the Earth's surface was hot and lifeless it is likely that asteroids formed in the same era as Bennu delivered the raw materials for life when they impacted our home planet long ago.
