Phil Whitmer Joshua Tree Earth & Space Museum --------------------------------------- Hello Mexico Doug, List, Thanks for the video. This concept of the evolution of the configuration of the stars of the Big Dipper is evidently widespread in China because it's even used in high-school teaching materials. This is why Wu Jiacai did not bother to list a source for his diagram of the evolution of the configuration from 100,000 BP to 12,000 AD. By the way, a stone originally owned by an antiquarian is claimed to be an even more ancient (150,000 yrs BP) map of the Big Dipper (http://61.128.162.70/stone/686/686.htm). Click once on the arrow below details (A), (b), and (C), and you see the current configuration of the Big Dipper; click a 2nd time, and you see the configuration 100,000 yrs in the future; click a 3rd time, and you see the configuration 100,000 yrs BP. One other figure in Wu Jiacai's scholarly article may interest astronomers; I've extracted and entitled it "Full19-StarConfig.jpg" at https://www.dropbox.com/gallery/18663629/1/Hongshan%20Cu15, 16, and 17 lture?h=bdfa66 It shows all 19 of the pockmarks on the rock that he regards as stars. The seven stars of the Big Dipper are linked by dotted lines. He says stars number 9, 10, 11, and 12 belong to Bootes, while 15, 16, and 17 are known as the "Three Stars." To hazard a guess, the "Three Stars" may be epsilon, sigma and rho Bootis, known in China for a few thousand years as "Genghe 1, 2, and 3," but of course he's talking about star positions 10,000 years ago. Lastly, he says that 13, 14, 16, 18, 19, and 20 are unknown as yet. Regards Robert A. Juhl, Tokyo Received on Tue 13 Sep 2011 10:58:04 AM PDT |
