INCOMING CME: This morning at 0120 UT, an eruption of magnetic fields around sunspot 1035 produced a long-duration C4-class solar flare and hurled a coronal mass ejection (CME) in the general direction of Earth. High-latitude sky watchers should prepare for auroras when the CME arrives on or about Dec. 18th Sunspot 1035 is growing rapidly and it is now seven times wider than Earth. This makes it an easy target for backyard solar telescopes. Yesterday, Rogerio Marcon of Campinas, Brazil, photographed a maelstrom of hot plasma and magnetic filaments connecting the sunspot's dark cores: Solar activity is picking up," he...

3200 Phaethon, an asteroid that is actually behaving like a comet. Scientists found dust that is streaming from this space rock as it gets close to the sun — similarly to how ices melt and form a tail as comets zoom by our closest stellar neighbor. Phaethon’s orbit puts it in the same originating region as other asteroids (between Mars and Jupiter), but its dust stream is much closer to actions performed by a comet — an object that typically comes from an icy region way beyond Neptune. So far, therefore, the research team is calling Phaethon a “rock comet.”...

Based on the flash brightness and duration of the St. Pat’s Day smack, the space boulder measured between one to 1.5 feet long (0.3-0.4 meters) and struck the moon traveling at 56,000 mph with a force of 5 tons of TNT. Scientists predicted then that the impact could produce a crater up to 65 feet (20 meters) in diameter.Before and after views of the March 17, 2013 impact taken by the LRO camera.

Explanation: On some nights it rains meteors. Peaking two nights ago, asteroid dust streaked through the dark skies of Earth, showering down during the annual Geminids meteor shower. Astrophotographer Juan Carlos Casado captured the space weather event, as pictured above, in a series of exposures spanning about 2.3 hours using a wide angle lens. The snowcapped Teide volcano of the Canary Islands of Spain towers in the foreground, while the picturesque constellation of Orion highlights the background. The star appearing just near the top of the volcano is Rigel. Although the asteroid dust particles are traveling parallel to each other,...

....The Geminids come from a small asteroid named 3200 Phaethon, which passes quite close to the sun. Its trail of dust and debris is what makes up the Geminids. Earth passes through this stream of debris every December. “Most meteor showers come from comets, which spew ample meteoroids for a night of ‘shooting stars.’ The Geminid meteor shower is different,” NASA writes in their Geminids site. “The parent is not a comet, but a weird rocky object named 3200 Phaethon that sheds very little dusty debris — not nearly enough to explain the Geminids.”.... “The Geminids are my favourite because...

Explanation: The annual Geminid meteor shower is raining down on planet Earth this week. And despite the waxing gibbous moonlight, the reliable Geminids should be enjoyable tonight (night of December 13/14) near the shower's peak. Recorded near last year's peak in the early hours of December 14, 2012, this skyscape captures many of Gemini's lovely shooting stars. The careful composite of exposures was made during a three hour period overlooking the Dashanbao Wetlands in central China. Dark skies above are shared with bright Jupiter (right), Orion, (right of center) and the faint band of the Milky Way. The shower's radiant...

Explanation: From a radiant point in the constellation of the Twins, the annual Geminid meteor shower rained down on planet Earth this week. Recorded near the shower's peak in the early hours of December 14, this skyscape captures Gemini's lovely shooting stars in a careful composite of 30 exposures, each 20 seconds long, from the dark of the Chilean Atacama Desert over ESO's Paranal Observatory. In the foreground Paranal's four Very Large Telescopes, four Auxillary Telescopes, and the VLT Survey telescope are all open and observing. The skies above are shared with bright Jupiter (left), Orion, (top left), and the...

The annual Geminids meteor shower will reach its peak late on Thursday night and into early Friday morning. The meteors will appear to radiate from a point near the star Castor, in the constellation Gemini. In the Northern hemisphere, that will be westward and nearly overhead in the early hours of Friday. Sky watchers can expect an average of dozens of "shooting stars" per hour, made easier to see by darkness provided by the "new moon" phase. The shower comes about each year as the Earth passes through the path of an asteroid called 3200 Phaethon.

Explanation: Some beautiful things begin as grains of sand. Locked in an oyster, a granule grows into an iridescent pearl, lustrous and lovely to behold. While hurtling through the atmosphere at 35 kilometers per second, a generous cosmic sand grain becomes an awe-inspiring meteor, its transient beauty displayed for any who care to watch. This years Geminid meteor shower peaked last week with sky enthusiasts counting as many as 150 meteors per hour, despite the din of bright moon. Pictured above the Taftan volcano in southeast Iran, a meteor streaks between the bright star Sirius on the far left and...

COLORADO SUPERBOLIDE: Last night, Dec. 6th at 1:06 a.m. MST, a meteor of stunning brightness lit up the skies of Colorado. Astronomer Chris Peterson photographed the event using a dedicated all-sky meteor camera in the town of Guffey, near Colorado Springs: Video:http://spaceweather.com/swpod2008/06dec08/Chris-Peterson1_strip.gif?PHPSESSID=s7mlc3ga8e6isub9bapbfqjkp2 "In seven years of operation, this is the brightest fireball I've ever recorded," says Peterson. "I estimate the terminal explosion at magnitude -18, more than 100 times brighter than a full Moon." Fireballs this bright belong to a rare category of meteors called superbolides. They are caused by small asteroids measuring a few to 10 meters in...

I was watching a movie several minutes ago (in West Palm Beach, FL) and saw out my window (facing east)a large shining object quickly plunge from the sky. It freaked me out a bit. Did anyone out there see it? I saw one similar back around 1990-1992 and years later saw it on Discovery as it was captured on video.

"It's the Geminid meteor shower," says NASA astronomer Bill Cooke of the Marshall Space Flight Center. "Start watching on Thursday evening, Dec. 13th, around 10 pm local time," he advises. "At first you might not see very many meteors—but be patient....

The Geminid meteor shower—considered by many to be the most active annual sky show—is going to be especially spectacular this year, astronomers predict. The show gets its name from the constellation Gemini, because the meteors appear to stream from near the constellation's bright star Castor. Unlike last year, the Geminids will be falling against a dark, moonless night. The last time the sky was this dark during the shower was in 1996, when observers saw up to 110 meteors an hour. Experts say the rate will be at least that high this year, with peak viewing on December 13 and...

The Geminid meteor shower, which peaks each year in December... are *not* caused by debris left behind from an active comet... Until recently, the favored view of Phaethon was that it's a dead comet -- the rocky core of a "dirty snowball" that lost its ices after too many close encounters with the sun. ... In June 2009 astronomers using the STEREO sun-watching probe suddenly saw the rocky body flare to life as it neared the sun, brightening by a factor of two... So, not so dead after all. But that brings us back to figuring out what exactly Phaethon...

For those in a clear and dark part of the world, the Geminids will continue this evening. Rates of 100 meteors per hour, with possible peaks of 140-150 per hour. Geminids are characterized by being slow moving and white, with the possibility of some fairly large fireballs! Happy gazing!

If you were disappointed with the meager showing put on by this year's Leonid meteor shower, don't fret. What could be the best meteor display of the year is scheduled to reach its peak on Monday night, Dec. 13. Skywatchers with dark skies away from city lights could see one or two meteors every minute during the Geminid meteor shower. The greatest activity is expected to be visible from North America, Europe and Africa. The Geminids get their name from the constellation of Gemini, the Twins. On the night of this shower's maximum, the meteors will appear to emanate from...
