Also (unrelated to the "Scale of the Universe 2") there will be an annular eclipse on Sunday. CLICK HERE to see a good short video produced by NASA. The best viewing will be in the southwest, but much of the west will see a "partial". Spaceweather.com is another good source. Select "animated eclipse map" to find out what the eclipse will look like from your state.
