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

Today's 2 topics:

- Given the effects of climate change today who can predict what planet Earth will be like when C/2023 P1(Nishimura) comes back near our home planet in approximately 2455 AD.

- Hycean Worlds, with masses between Earth and Neptune which have thin hydrogen rich atmospheres above a liquid water ocean may be very common in our neighborhood of the Milky Way. They could be an abode of life.
