GM "What's Out There Beyond Neptune?  -- The Outer Solar System" by Tom Eason
Ron Olson substituted for Tom Eason. Almost everybody understands the basic layout of the planets in our solar system. But that general knowledge stops at Neptune or maybe Pluto, the recently “demoted” farthest planet. But our solar system extends far beyond there. Ron's presentation explained what’s out there and why. He described the three general groupings of those distant bodies; the Kuiper Belt, the Scattered Disc, and the Oort Cloud, and also a few "oddballs" that don’t fit any of the groups.

March CIG Video Lecture
Lecture 35 - What's Next for Cosmology?
GM "Black Holes, Black Stars, and Naked Singularities - When gravity rules, weird things happen" by Tom Eason
Black holes are curiosities of the first order. Just about everybody knows a little bit about them. “Once something goes in, it will never come out.” There is a lot more about them that is interesting beyond just this central property. Tom explained how and where they are born, how they are structured, how they grow (and sometimes shrink).  He discussed Black Stars, which are “would be” black holes that didn’t quite make the grade, and Naked Singularities. They are related to black holes, and may be real or just scientific fancy, but either way they stretch one’s imagination.
