Best Meteor shower peaks 2010 tonight (SPACE.com)

What promises to be the best meteor shower of the year is hitting its peak just in time for the holidays, but skywatchers should act quickly: this show sky peaks tonight.At night in the heart of the spectacle of skywatching is the these shower meteors, a mid-December annual Meteor rain which will reach its peak (13 December) this evening and tomorrow morning. Weather and beautiful clear skies could see meteors to 120 the meteor shower rush hour.

The sky map shows where to look to see the shower of meteors during these peak, December 13 and 14 December. Meteors will appear emanate a spot in the sky near Beaver bright star in the constellation of Gemini (twins), which gave the shower his name.

The Geminids are one of the most reliable "shooting stars" monitors each year and 2010's display should not disappoint. The Geminid must be clearly visible for skywatchers in Northern by late tonight, but display conditions will improve significantly once the Moon sets to 12: 30 local time tomorrow morning. Stay warm, searchThe best time to watch Meteor Gemind will be at 6 pm EST (1100 GMT), when the shower should be at its most active.

Because Gemind meteor shower occurs during the winter for skywatchers North America, there are a few tips to remember from venturing outside the chilly December night.

"At this time of year, meteor watching can be a company long and cold," advises skywatching columnist SPACE.com Joe Rao. You expect and that you expect from meteors to appear. When they are not immediately, and if you are cold and uncomfortable, you will not seek Meteor for very long. Therefore, ensure that you are warm and comfortable. »

Warm coats and blankets, as well as a comfortable recliner lawn is vital for skywatchers committed assets hoping to observe the Geminid.

Rao said that the Geminids are "usually the most satisfactory and showers annual." They may even exceed the apogees August famous Perseid Meteor Shower. »

The Leonids, observing the advice

Skywatching McDonald Observatory in Texas star magazine editors also warn skywatchers away from city lights if they want to get the most beautiful view of the meteor shower.

"Locate parks State or city or other safe and dark sites." "Lie on a blanket or a recliner to get a view full sky" stellar magazine said in a statement. "If you can see all the stars in small saucepan, you have a vision for good."Meteors occur when the Earth passes through the debris left by a passing Comet or asteroid a runway. As the Earth passes through these trails, the remains of the dust and rocks touched the Earth atmosphere and burns in a fiery Meteor. In space, these objects are called meteoroids. They are called Meteor when they burn in the Earth's atmosphere. The meteors that reach the ground are called meteoroids. Shower meteors these has been identified in the 1860s, but it was not until 1983, when a NASA satellite Rocky asteroid 3200 Phaethon as the shooting star display source. "When the Geminid emerged at the end of the 19th century, shortly before the American civil war, the shower was low and raised little", NASA officials said in a statement. "Is there any indication that it would never become an important display."Now the meteor shower anticipated eagerly to dazzle skywatchers annually. But asteroid 3200 Phaethon still poses a mystery to astronomers because it does not seem to create enough debris to take account of the spectacular poster created by meteor shower these every year, NASA scientists have said. "The Geminids are my favorite, because they defy explanation, said NASA astronomer Bill Cooke, a Meteor at Marshall Space Flight Center in Huntsville, agency expert ALA, in a statement." Cooke will host "Up All Night" event NASA Marshall Center during the meteor shower these. Event gives skywatchers will hold a chance to check the meteor shower these without venturing outside the cold.NASA web chat to discuss the Geminids in 15 h EST GMT today (2000), then turn the Cooke night at 11 pm (EST) (December 14 0400) for a six-hour observation campaign Geminid. Meanwhile, Cooke will be on hand to answer questions via web chat on how these 2010 Meteor display appears.

Neil Armstrong explains his famous Moonwalk of Apollo 11 (SPACE.com)

Astronauts of Apollo 11 Neil Armstrong can be notoriously private, but the first man on the moon has recently concluded a journalist to share some new details about its famous not on the moon with fellow Astronaut Buzz Aldrin in 1969.

It all started with a blog that has been published on Tuesday (7 December) on the website of the National Public Radio (NPR). Post reviewed Armstrong and aldrin's celebrated the first on the moon on July 20, 1969 and asked why the first exploration of the lunar surface covered a small distance.

Robert Krulwich of NPR has looked at a map of NASA which marks all places on the surface of the Moon was visited by Armstrong and Aldrin. He then superimposed this map on a field and regulation soccer baseball diamond.

In so doing, Krulwich determined the pitch on the historic moon took the astronauts less than a hundred metres from his Lunar Lander. Or, in the perspective of a baseball field "walking longer, more daring taken Armstrong on as Joe DiMaggio used for each ? plate on jogging round mid-center field."

The next day, Krulwich posted a follow-up, which featured a response by email Neil Armstrong himself.

In its reply, Armstrong, who was the Commander of the Apollo 11 flight, explained the reasons for a small distance, which includes extremely temperatures on the lunar surface, uncertainties, how combinations of astronauts with their interiors water-cooled could delay and requirements of the NASA, the two astronauts experience in front of a camera fixed.

Armstrong wrote: "we do have not all data to tell us how long in our backpacks small water tank is sufficient. "NASA officials limited our time working surface to 2 and 3/4 hours on this first exploration surface to ensure that expire not hyperthermia.". After return and repressurizing the lunar module, we were able to drain and measure water remains in the bags back to confirm the predicted. »

Armstrong said that if he had more free time, he and Aldrin wanted to explore further the lunar surface.

"It's true that we would have liked to stay on the surface long and busy later lunar module and the TV camera," he wrote. "But we had a number of experiments to install, to document and collect samples and take photographs." The time available has been entirely allocated and we have worked diligently to complete assigned tasks.

Armstrong goes on to say later flights Apollo were able to cover more ground thanks to the addition of the Lunar rovers, but there is still a vast rest world to discover.

Armstrong said "Americans visited and reviewed 6 locations on Luna, varies in size commuter lot in a small township, "Leaving more than 14 million kilometres square yet to explore".
