Just to spread the word about a project some friends of mine are involved in: The Vatican Observatory Podcast.

Despite the name, it's about science, not Catholicism. The host/moderator is Bob Trembley, a friend of mine for decades (since college in the early 80s) and a constant guest is Br. Guy Consolmango, the director of the Vatican Observatory (and whom I know through General Technics).

Both Bob and Br. Guy are popular speakers at SF conventions, on topics of space, space exploration, meteorites, and other astronomical subjects.

The podcast does not have a regular schedule, but it's available at the usual places, and also at https://www.vaticanobservatory.org/podcast/
