Podcaster: Dr. Al Grauer
Title: Travelers in the Night Eps. 755 & 756: Geyser of Life – Maybe & Nice PHA
Organization: Travelers in The Night
Link : Travelers in the Night ; @Nmcanopus
Description: Today’s two stroy:
- 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.
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.
