Travelers in the Night Eps. 219E & 220E: Hot Hand & Dangerous Aten
The 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. Today's 2 topics: - Every year asteroid hunters discover about a hundred objects which are larger than 450 feet in diameter and come closer than 20 times the Moon's distance from us. We call these potentially hazardous asteroids. In 2015 my group the Catalina Sky Survey discovered 21 of them. It was thus exciting news to our team, when, recently, our newest team member Greg Leonard discovered three of them in rapid...

Last Minute Astronomer - December 2023
The 365 Days of Astronomy
Some slight changes to Saturn and Jupiter in the sky, the start of a big change for Venus, and even more rocks fall from the sky this December here on the Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare. Let’s start by talking about the naked eye planets visible this month, the lunar phases, and then the meteor shower and other events, so you can plan ahead better than me. 13th/14th – Geminid Meteor Shower – A VERY good year for this shower, as there is only a thin crescent Moon which sets early. So get out there and...

Travelers in the Night Eps. 217E & 218E: Close Duo & Close or Not
The 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. Today's 2 topics: - On consecutive nights my Catalina Sky Survey teammate Richard Kowalski discovered two very close approaching asteroids. One of Richard's discoveries, 2016 BY14 must be made out of pretty tough stuff since when it was closest to the Sun it received more than twice the solar energy which heats the surface of Mercury to 800 F. Asteroid hunter's continue to need to track 2016 BY14 to make sure that its orbit...

Today's 2 topics:
- The NASA Mars Opportunity Rover, nicked named Oppy by those who operate and love it ,was designed to last 90 days on the Martian surface but has continued to explore the surface of the red planet for 14 years.
- What asteroid hunters fear is that a small space rock capable of injuring people and damaging buildings is heading our way and that we will not find it in time to give a warning for people in the impact area to seek cover.
