SUNSET: 
Geminids in the Moonlight
With an average of 100 meteors per hour radiating from near the bright star Castor, this end-of-the-calendar shower is usually one of the year’s best. However, this week's performance will be spoiled by a just-past-full Moon that rises not long after the radiant clears the northeastern horizon.
December 10th's Colorful Lunar Eclipse
The last total lunar eclipse for the next 2½ years was widely observed by skywatchers around the Pacific Rim.
Comet Lovejoy's Date With Destiny
Discovered in late November by a veteran Australian comet-hunter, C/2011 W3 is a kamikaze comet that will pass just 116,000 miles from the Sun on December 16th. Will it dazzle us as it falls inward? Will it survive its close brush with the Sun? Amateur astronomers worldwide are holding their collective breath!
Comet Garradd in Transition
A decently bright visitor from the solar system’s fringe has lingered in the evening sky for months. As it nears perihelion, Comet Garradd (C/2009 P1) will soon be seen better in northern morning skies before dawn.
Tour December's Sky! | November 26th, 2011
Venus lurks low in the western twilight after sunset. But after it gets good and dark, swing around to the east to see dazzling Jupiter, the King of Planets, amid a tower of brilliant early-winter stars that extends from the horizon to overhead.
Black Friday's Partial Solar Eclipse
On what's become the busiest shopping day of the year, a deep partial solar eclipse swept across the bottom of the world.
A Dawn Eclipse of the Moon
The Moon will become totally eclipsed for much of North America before sunrise on December 10th.
Mini-Asteroid Makes a House Call
You've probably heard by now about 2005 YU55. This quarter-mile-wide asteroid will coast past Earth on the night of November 8–9, shining at 11th magnitude and providing a rare opportunity for professional and amateur observers alike.
Tour November's Sky! | October 28th, 2011
With the return to Standard Time for North America and Europe, northern stargazers can catch some of the evening's offerings before dinnertime. Venus and Jupiter are planetary bookends at sunset, with Venus lurking low in the western twilight just as the King of Planets rises in the east.
Comet Elenin's Last Gasp
It was never going to be an "extinction-level" threat to Earth, but skygazers had hoped that Comet Elenin (C/2010 X1) would put on a decent show in October's predawn skies. In the end, however, it just went "poof".
The Great World Wide Star Count
Join thousands of other "citizen scientists" in raising dark-sky awareness around the globe.
Draconid Meteors Arrive As Forecast
Chalk up another win for the meteor-shower modelers. Europeans saw a display of up to a couple hundred Draconid meteors per hour on Saturday evening.
A Mad Dash for the Draconids
If celestial prognosticators are right, the little-known Draconid meteor shower could deliver hundreds of "shootings stars" per hour during a brief window on Saturday, October 8th. But the outburst's timing favors Europe, not North America.
Tour October's Sky! | September 30th, 2011
This is a month of transition: Northern summer becomes autumn, Saturn sets just before Jupiter rises, and Venus is moving from the morning sky before dawn to the evening sky.
Observe Mira, the Amazing Star
The extraordinary variable star Mira is expected to peak in early October, 2011.
M101's Supernova Shines On
As of October 3rd the supernova in the galaxy M101 was down to about magnitude 11.1, after peaking in mid-September at 9.9. It's fading by about 0.1 magnitude every two days now, and it has changed from white to strikingly orange-red.
Antiope Occultation Yields Double Bonanza
When observers fanned out last July 19th to record a binary asteroid's passage across a distant star, they hoped to gain scientifically important new findings. The results are in, and they've scored big-time!
Trusty Comet Garradd
Comet C/2009 P1 Garradd is shining at 7th or maybe even 6th magnitude as it traverses southeastern Hercules.
Lots Going On in the Sky
The first week of September will be a memorable time for observers in the Northern Hemisphere.
