Stunning Sky on Monday Evening

Source - Space Weather News for Monday, Dec. 1, 2008: http://spaceweather.com

When the sun goes down tonight, step outside and look south. Beaming through the twilight is one of the prettiest things you'll ever see--a tight three-way conjunction of Venus, Jupiter and the crescent Moon. The event is visible from all parts of the world, even from light-polluted cities. People in New York and Hong Kong will see it just as clearly as astronomers watching from remote mountaintops. Only cloudy weather or a midnight sun (sorry Antarctica!) can spoil the show.

The great conjunction offers something extra to Europeans. For more than an hour on Monday evening, the crescent Moon will actually eclipse Venus. Astronomers call such an event a "lunar occultation." Venus emerging from the dark edge of the Moon is a remarkably beautiful sight. Sky watchers across Europe will be able to see this happen.

Are We Alone for 12/01/08 - Got Life?

Are We Alone

Are We Alone - "Got Life?"
"Spore" is the ultimate game of life. Play it wisely and you can evolve from a single-celled organism, swimming in salt water, to an intelligent being rocketing through the galaxy. It's survival of the cleverest - are you game?

Join us as we attend the "Spore" launch party. Hear how the game's primary author, Will Wright (of "SimCity" fame) simulated the arc of evolution; whether complex life is inevitable; and how SETI scientists inspired one of the most anticipated video games in history.

Also, why real human evolution is picking up the pace (did you know that blue eyes are relatively new?)... and a doctor's film about the meaning of life.

Double Flyby Alert

Source - Space Weather News for Nov. 28, 2008: http://spaceweather.com

DOUBLE FLYBY ALERT: Space shuttle Endeavour undocked from the International Space Station this morning, and the two spacecraft are now orbiting Earth in tandem. Endeavour is scheduled to land in Florida on Sunday, Nov. 30th. Between now and then, many sky watchers (especially those in Europe) will be able to see the shuttle and the space station cutting across the night sky together--a rare and beautiful "double flyby." Get predictions for your hometown from the Simple Satellite Tracker: http://spaceweather.com/flybys .

SPECTACULAR CONJUNCTION: When the sun goes down tonight, step outside and look southwest. You'll see something very pretty: Venus and Jupiter beaming together through the twilight. The two closely-spaced planets are about to be joined by the slender crescent Moon for a spectacular three-way conjunction that arguably ranks as the best sky show of 2008. Check http://spaceweather.com for sky maps, photos--and be sure to keep an eye on the sky in the evenings ahead.

Runaway ISS Toolbag Sighted and Filmed

Source - Space Weather News for Nov. 25th: http://spaceweather.com

ISS TOOLBAG: A backpack-sized tool bag inadvertently dropped from the International Space Station last week is orbiting Earth and has been sighted from the ground. The tool bag is surprisingly bright, about 6th or 7th magnitude, which makes it an easy target for binoculars or a small telescope. Today's edition of http://spaceweather.com offers observing tips, sighting reports and a movie of the bag in orbit.

AURORA WATCH: High-latitude sky watchers should be alert for auroras tonight and tomorrow. Earth is entering a solar wind stream and this could trigger geomagnetic storms around the Arctic Circle.

Discovered: Cosmic Rays from a Mysterious, Nearby Object

NASA Science News for November 19, 2008

An international team of researchers has discovered a puzzling surplus of high-energy electrons bombarding Earth from space. The source of these cosmic rays is unknown, but it must be close to the solar system and it could be made of dark matter.

Converging Planets and Leonid Meteors

Source - Space Weather News for Nov. 16, 2008: http://spaceweather.com

EVENING PLANETS: When the sun goes down tonight, step outside and look southwest. The two brightest planets, Venus and Jupiter, are shining through the twilight side by side. You'll want to keep an eye on these two because they are drawing noticeably closer together every night. Venus and Jupiter are converging on a patch of sky in Sagittarius where they will have a spectacular double-conjunction with the Moon at the end of the month. Don't wait until then, though. Visit http://spaceweather.com for sky maps and start watching now.

LEONID METEOR WATCH: The Leonid meteor shower peaks this year on Nov. 17th and 18th. Bright moonlight will probably spoil the show, but not necessarily. Researchers who study Comet 55P/Tempel-Tuttle, the source of the Leonids, say Earth is going to pass through one or two of the comet's dusty filaments. Peak rates of 20 to 100 meteors per hour are possible during the early hours of Nov. 17th (especially 0000-0200 UT) and again during the waning hours of Nov. 18th (around 2130 UT). These times favor sky watchers in Europe, Africa, and Asia. Smaller numbers of Leonids could appear between the anticipated peak times. Meteor enthusiasts everywhere should monitor the sky on Nov. 17th and 18th; the hours before local dawn are usually best.

NASA Begins Hunt for New Meteor Showers

Source - NASA Science News for November 10, 2008

NASA astronomers have set up a monitoring station to scan the night sky for unknown or unexpected meteor showers--and they're finding more than they bargained for. In only two months of observing, the newly commissioned system has captured a flurry of meteors from an unknown comet and an object from the asteroid belt exploding like 500 lb of TNT. See the movies in today's story.

Taurid Meteor Shower

Source - Space Weather News for Nov. 6, 2008: http://spaceweather.com

TAURID METEOR SHOWER: The annual Taurid meteor shower is underway and it could be a good show. 2008 is a "swarm year" for the Taurids. Between Nov. 5th and 12th, Earth is due to pass through an unusually dense swarm of gritty debris from parent comet 2P/Encke. When a similar encounter happened in 2005, sky watchers observed a slow drizzle of midnight fireballs for nearly two weeks. Whether 2008 will be as good as 2005, however, remains to be seen. In 2005, the swarm encounter was more central; Earth passed through the middle of the cloud. In 2008, forecasters believe we are closer to the outskirts. How much this will affect the shower, no one knows. The best time to look is during the hours around midnight when the constellation Taurus is high in the sky.

Visit http://spaceweather.com for sky maps and photos of the ongoing shower.

ISS Space Junk Reentry

Source - Space Weather News for Nov. 1, 2008: http://spaceweather.com

More than a year ago, in July 2007, International Space Station astronauts threw an obsolete, refrigerator-sized ammonia reservoir overboard. Ever since, the 1400-lb piece of space junk has been circling Earth in a decaying orbit--and now it is about to reenter. If predictions are correct, the "Early Ammonia Servicer" (EAS for short) will turn into a brilliant fireball as it disintegrates in Earth's atmosphere during the early hours of Monday, Nov. 3rd. Uncertainties in the exact reentry time are so great (plus or minus 15 hours at the time of this alert) that it is impossible to pinpoint where the fireball will appear. At the moment, every continent except Antarctica has some favorable ground tracks.

Readers should check our Satellite Tracker (http://spaceweather.com/flybys/) for possible overflights. Before reentry, the EAS will seem about as bright as a 2nd or 3rd magnitude star, similar to the stars of the Big Dipper. During re-entry, the disintegrating reservoir could light up like a full Moon. Flyby predictions should be regarded as approximate because the orbital elements of the EAS are now changing so rapidly. Updates will be posted on http://spaceweather.com.
