Travelers in the Night Eps. 755 & 756: Geyser of Life – Maybe & Nice PHA

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 July 28 & August 4, 2023. Today's 2 topics: - In 2023 the James Webb Space Telescope spotted a geyser of water vapor extending more than 80% of the Earth’s diameter erupting from Saturn’s moon Enceladus. If life does exist in the salty ocean of Enceladus shielded from the rest of the Universe by a thick layer of ice and rock its nature remains a mystery. - My Catalina Sky Survey teammate David Rankin was asteroid hunting in the constellation of Cancer with our Schmidt telescope on Mt. Bigelow, Arizona when he discovered a potentially hazardous asteroid, 2023 KM5. Rest assured there is no way, on its current path, that 2023 KM5 will impact the Earth in the foreseeable future, however, asteroid hunters will continue to track it to make sure its orbit does not change to make it a threat.   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!
