Travelers in the Night Eps. 337E & 338E: Seeds & Double Trouble

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 May 2025. Today's 2 topics: - When a fleet of interstellar spaceships leaves our solar system for a planet circling a nearby star the most important of all of the riches that human explorers will carry with them will be libraries of our planet's DNA and the seeds of plants. They are the connection between past life, the inorganic world, and future life.   - When I discovered 2014 JO25 with the NASA funded Catalina Sky Survey's 60 inch telescope on May 5, 2014, it appeared as a single point of light as it moved past us. As 2014 JO25 approached the Earth from the direction of the Sun in 2017, no-one had any idea that it is really a double asteroid system nearly a mile in diameter.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
