Travelers in the Night Eps. 679 & 680: Hammer & Comets and Asteroids

<p>Dr. Al Grauer hosts. Dr. Albert D. Grauer ( <a href= "https://twitter.com/Nmcanopus">@Nmcanopus</a> ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. <a href= "http://travelersinthenight.org">travelersinthenight.org</a></p> <p><strong>Today's 2 topics:</strong></p> <p>- When Asteroid Hunters find a relatively large asteroid on a collision course with planet Earth, the challenge is to change its path to make it miss our home planet.</p> <p>- If you set your mind to it, you can find and hold a sample of an asteroid, called a meteorite, which has landed on the Earth's surface. On the other hand, watching major meteor showers will allow you to see but not touch comet dust as it enters and burns up in the Earth's atmosphere.</p> <p> </p> <p>We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.<span class= "Apple-converted-space"> </span></p> <p>Just visit: <a href= "https://www.patreon.com/365DaysOfAstronomy">https://www.patreon.com/365DaysOfAstronomy</a> and donate as much as you can!</p> <p>Share the podcast with your friends and send the Patreon link to them too!<span class="Apple-converted-space"> </span></p> <p>Every bit helps!
