Look Up: What's in the Sky This Week?

Did you look up last Wednesday and Thursday to see two of the brightest objects in the sky -- the Moon and Jupiter -- trek ever so close to each other? It's tough to say that maxedaperture's photo above doesn't really do it justice (because it sure as hell does the Moon itself justice), but the real view was so bright to make even non-fans of astronomy look up and, as a friend told me later, make him nearly run his car into a ditch. (Please practice safe sky viewing and pull over!)

If you missed it, never to worry: the solar system keeps spinning and bringing us more sights to look forward to. The Perseid meteor shower peaks this week, on Tuesday and Wednesday. The "shooting stars" are little pieces of Comet Swift-Tuttle, which we last saw in 1992 (and won't see again until 2126) and, because its orbit brings it so close to Earth, its predicted to quite possibly be the bringer of our eventual doom -- but we'll leave that for our great-great-grandkids to worry about. In the meantime, however, that means the comet swings close enough to throw quite a bit of debris into our atmosphere. Naturally, the shower dims every year as the comet travels back out into the solar system, and we'll have a little bit of the bright quarter Moon to outshine the meteors as they vaporize overhead, but the Perseids always bring a bit of a show no matter what. To find them, look towards the northeast sky near the constellations Perseus and Cassiopeia between 11 p.m. and dawn both nights.

If planets are more your thing, you'll have some more good viewing opportunities. Though its moved away from the Moon, Jupiter is still an incredible sight, reaching opposition -- that is, the Sun and the planet are on exact opposite sides of the Earth -- on Friday. At opposition, Jupiter's orbit brings it closest to us, so it will be incredibly bright and visible from sunset to sunrise.

Sky watchers should also stay tuned to DCist on Monday, when we'll bring you a tour of the brand new Public Observatory at the National Air & Space Museum, scheduled to open later this month.

Saturn also pulls a neat trick this week, though it won't be visible to our eyeballs. Once every 15 years, its equator lines up so that the Sun's rays hit its rings head-on, essentially making them disappear, or, as NASA puts it, "pull a Celestial Houdini." Galileo Galilei first saw it happen in 1612 as he studied Saturn's moons, but this year the planet is too close to the sun for us to see with basic telescopes. Instead, we'll get to see some incredible pictures from the Cassini-Huygens mission, which launched in 1997 and reached the planet in 2004, and is ready to discover things that can only be seen in this light. Check back with their images site to see them.

Want to do more than look up? Head over to George Mason tomorrow for the monthly meeting of the Northern Virginia Astronomy Club. The meetings are open to the public (but the $25 annual membership is probably less than your beer tab last night) and include an Observing Report, a show and tell featuring new astronomy gadgets, plus a discussion on this month's topic, lunar observing.

If the weather doesn't cooperate this week, consider heading over to the National Air & Space Museum for a show at the Albert Einstein Planetarium. Cosmic Collisions and Black Holes: The Other Side of Infinity alternate and run about 20 minutes each. It's no Pink Floyd laser show, but you do get to sit back in your recliner and listen to some famous voices narrate celestial happenings. Did you know the Moon was created in just one month? (Ask Robert Redford how!) Tickets are under $10 each, discounted if you buy both.

I saw it on thursday and couldnt stop looking!

found this great program to check out your sky before going outside! its MAC/PC/Linux ready and free!

http://www.stellarium.org/

Another cool star-gazing tool is pUniverse for the iphone (http://bit.ly/puniverse). If you have one of the new iphones (w/compass) you just point the phone up at the sky and it shows you what's there.

THAT'S NO MOON.....

I really like these updates
