Courtesy Mark RyanThe definition in an astronomical sense is when three or more celestial bodies in the same gravitational system line up in essentially a straight line. One example would be the Sun, Moon, and Earth during an eclipse. Another may be the phenomenon that was visible in the western sky just after dusk today.
Courtesy Makr RyanHere are four photographs I shot of the alignment of the Moon with the planets Jupiter and Venus. I don't know if the celestial alignment is technically a syzgy but the word has stuck with me and I'm still waiting to use it in a game of Scrabble.

That's what all the streaks and extra lights in the photos are. The exposures were long, ranging between 6 and 15 seconds, and I used a timer so as not to shake the camera during each exposure. Timing the shutter with the aircraft was tricky but I got a few good ones.
Two of the brightest planets, Venus and Jupiter, appear very close together tonight. Tomorrow night (Dec 1) they will be joined by the crescent moon around 6 pm (CDT) to make an "unhappy face".
"This is set to be the best planetary gathering of the year, simply because it involves three of the brightest objects in the sky after the sun," said Geza Gyuk, director of astronomy at the Adler Planetarium in Chicago. National Geographic.
