Ver y interesting. This will prompt me to do some quick internet searches about the metoeorites, rare organic ones. Thanks for posting Chrismo. BTW, Phil Plait was certainly entertaining (although pretty basic for those actually interested in astronomy). The room where the presentation was held could seat 400-500 and it was SRO. Most of the attendees were college age. In addition, they had cookies and punch available afterward and a number of tables set up manned by various people to demonstrate astronomical things. I stopped at one table and talked to a "kid" (gad he was in college, they ought not be kids by then lol) with an ipad. He had messed around with the college's scope and took some white light and hyrdogen-alpha photos of the sun. The h-a picture was great. Not only granulation and sun spots, but he captured a lot of prominces on the edge. Cool . I would have liked to formally meet up with Dale and Jared, introduce myself, but I met up with friends who live in Mendon and we barely made it to the lecture. We arrived at 7:03. (Crap, I wanted to be there 15 minutes early). Oh well, I had a great time visiting with them and they thoroughly enjoyed the lecture.
