Sweatman and Dimitrios Tsikritsis from the Universi- ty of Edinburgh (School of Engineering) have suggested an interpretation for the early Neolithic monumen- tal enclosures at Göbekli Tepe as space observatories and the site's complex iconography the commemora- tion of a catastrophic astronomical event ('Younger Dryas Comet Impact'). As the archaeologists excavating this site, we would like to comment on a few points that we feel require consideration in this discussion. -
The Night Sky Saturn at Opposition This Month
The Night Sky Saturn at Opposition this Month Last month we saw the “king of the planets,” Jupiter, at opposition. This month, the ringed planet, Saturn, is at opposition in late June. Before describing the whereabouts of our solar system’s gas giants, let’s see what is going on in the evening sky. Venus continues to dominate the evening twilight in the western sky and will remain visible for up to two and a half hours after sunset. Venus attains its highest sunset altitude on June 6th and brightens throughout the month – there is no mistaking which “star-like” object is Venus in the western evening sky, since it outshines all of our nighttime celestial objects except the moon. As the sky darkens, you will note the two bright stars of Gemini, Pollux and Castor, just to the upper right of brilliant Venus. In mid- June, sharp-eyed observers will spot our innermost planet Mercury hanging above the west-northwest horizon one-half hour after sunset. On June 14th, assuming one has an unobstructed western horizon, one will be able to spot a thin waxing crescent moon just to the left of Mercury. Looking toward the southwest in the evening, Jupiter dominates the stars in that part of the sky. As one is looking at Jupiter, you will note a fainter star just to the lower-left of Jupiter. That star is the second brightest star in the constellation of Libra, Alpha Librae. Typically the ``alpha’’ label is applied to the brightest star of a constellation, however this is one of the few exceptions to this rule. -

The Flint River Observer
THE * * * President‟s Message. The “Journey to the Stars” dvd FLINT RIVER we watched at the March meeting may or may not have answered a question I‟ve often wondered about. OBSERVER In my recent 3-part article series, “The Trivia Question That Grew” (The Observer, Dec. ‟10-Feb. ‟11), I glossed over the problem, hoping you wouldn‟t NEWSLETTER OF THE FLINT notice the omission. Other writers have done the RIVER ASTRONOMY CLUB same thing because they didn‟t know the answer, either. Here‟s the problem: An Affiliate of the Astronomical League About 11 billion years ago, the Sun formed out of a dense cloud of gases and dust that was left over Vol. 15, No. 2 April, 2011 from an earlier supernova explosion.

Sky certainly didn‟t know – was, What was the mass that View Coordinator, Steve Bentley; Observing attracted those nebular gases?
