Podcaster: Dr. Al Grauer
Title: Travelers in the Night Eps. 697 & 698: Double Trouble & Aliens?
Organization: Travelers in The Night
Description: Today’s two stroy:
- Asteroid hunters have discovered a strange asteroid pair. How they came to be together and what humans would do if such a large double trouble object is heading for us remains a mystery.
- Most Astronomers find it hard to believe that given perhaps a trillion planets in the Milky Way alone that our Earth is the only one which hosts living organisms. It is both exciting and terrifying to realize we have no concept of what living forms may exist outside Earth in the Milky Way.
Bio: Dr. Al Grauer is currently an observing member of the Catalina Sky Survey Team at the University of Arizona. This group has discovered nearly half of the Earth approaching objects known to exist. He received a PhD in Physics in 1971 and has been an observational Astronomer for 43 years. He retired as a University Professor after 39 years of interacting with students. He has conducted research projects using telescopes in Arizona, Chile, Australia, Hawaii, Louisiana, and Georgia with funding from NSF and NASA.
He is noted as Co-discoverer of comet P/2010 TO20 Linear-Grauer, Discoverer of comet C/2009 U5 Grauer and has asteroid 18871 Grauer named for him.
