Become an Exoplanet Hunter With Newest Zooniverse Citizen Science Project – Planet Hunters is the latest in the Zooniverse project, and users will help scientists analyze data taken by NASA’s Kepler mission, the biggest, badest exoplanet hunting telescope in space. The project goes live on December 16 at http://www.planethunters.org. –Nancy Atkinson / Universe Today

Could This be the Start of a New Space Shuttle? – All is not lost for the space shuttle idea. Richard Branson is thinking big again and along with orbital sciences Corp, Sierra Nevada Corp and some others they may build a reusable taxi to space just like the space shuttle. NASA will find $200 million to help with the development. –Weirdwrap

Bright White Storm Raging on Saturn – About a week ago, a bright white storm emerged on Saturn’s northern hemisphere, and amateur astronomer/planet astrophotographer extraordinaire Anthony Wesley from Australia has captured a few images of it. “This is the brightest Saturn storm in decades,” Anthony said on his website, Ice In Space. “If you get a chance to see it visually then take it, as it may be one of the rare “Great White Spot” (GWS) outbreaks on Saturn.” –Nancy Atkinson / Universe Today

Launch of TMA-20

Soyuz lift-off with ESA astronaut Paolo Nespoli together with Dmitri Kondratyev and Catherine Coleman for a challenging 6-month mission on the International Space Station (ISS) as members of Expeditions 26/27. They were launched in the Soyuz TMA-20 spacecraft from Baikonur Cosmodrome in Kazakhstan on 15 December at 19:09 GMT. Paolo’s MagISStra mission will be Europe’s third long-duration mission on the ISS. Between December 2010 and June 2011 he will be part of the ISS crew as a flight engineer. - Credit: ESA - S.

Phobos shadow passing over Viking 1 landing site dust storm (40x actual speed) - On September 28, 1977, Viking Orbiter 1 observed a dust storm over the site where it had dropped its lander, more than a year previously. As Viking 1 orbiter watched, the shadow of Mars' inner moon Phobos passed over the cloud tops. Data: NASA/JPL. Processing: Daniel Machá?ek

NASA Discovers Asteroid Delivered Assortment of Meteorites – An international team of scientists studying remnants of an asteroid that crashed into the Nubian Desert in October 2008 discovered it contained at least 10 different types of meteorites. Some of them contained chemicals that form the building blocks of life on Earth, and those chemicals were spread through all parts of the asteroid by collisions. –NASA

Near-Synchronous Explosions Connect Across the Vast Distances on the Sun – For several decades, scientists studying the sun have observed solar flares that appear to occur almost simultaneously but originated in completely different areas on the Sun. Solar physicists called them “sympathetic” flares, but it was thought these near-synchronous explosions in the solar atmosphere were too far apart – sometimes millions of kilometers distant – to be related. But now, with the continuous high-resolution and multi-wavelength observations with the Solar Dynamics Observatory, combined with views from the twin STEREO spacecraft, the scientists are seeing how these sympathetic eruptions — sometimes on opposite sides of the sun — can connect through looping lines of the Sun’s magnetic field. –Nancy Atkinson / Universe Today

Galaxy Cluster Reveals Farthest Known Galaxy – Almost all of the bright objects in this Hubble Space Telescope image are galaxies in the cluster known as Abell 2218 -a cluster so massive and so compact that its gravity bends and focuses the light from galaxies that lie behind it. As a result, multiple images of these background galaxies are distorted into long faint arcs. –The Daily Galaxy

No Asteroid Particles Found in Second Hayabusa Compartment, But More in First – No visible material from asteroid Itokawa was found inside the second compartment of a canister returned to Earth by the Hayabusa spacecraft. However, JAXA also announced that more micron-sized grains have been found in the first compartment, opened earlier this year. –Nancy Atkinson / Universe Today

93rd Birth Anniversary of Sir Arthur Clarke – Let’s cherish the 93rd birth anniversary of Sir Arthur Clarke, who rendered an immense service to the world, by means of his innovative concepts on telecommunication + thrilling scientific books, We should do something to remind the world about his being in a day like this, as what his imagination has rendered, continues to grow day by day –IYA 2009 / Sri Lanka

A Majestic Galaxy in One of the Largest Known Structures in the Observable Universe – This image shows a majestic face-on spiral galaxy located deep within the Coma Cluster of galaxies, which lies 320 million light-years away, in the northern constellation Coma Berenices. The galaxy, known as NGC 4911, contains rich lanes of dust and gas near its center. These are silhouetted against glowing newborn star clusters and iridescent pink clouds of hydrogen, the existence of which indicates ongoing star formation. –The Daily Galaxy

Dec 14/15 Meteors (night after the Geminids peak) – What a difference 24 hours makes! Only a day removed from the Geminids peak and rates have crashed to a fraction of their peak. During the past 5 nights SALSA3 detected 12, 22, 69, 124 and now 20 Geminids. This is a characteristic of the Geminids in that the post-peak rates fall off much more rapidly than the pre-peak increase. –Carl Hergenrother

Meteors and the Geminids Peak – The Geminids did not dissapoint! Though the IMO ZHR Live page doesn’t seem to be updating observations made by myself and Salvador show ZHRs that equaled or even exceeded the expected value of 120.

Breaking News: Space Shuttle Discovery to Be Rolled Back from Launchpad – NASA managers made the decision on Monday afternoon that space shuttle Discovery will be rolled back from the launchpad for inspections and/or repairs. There’s no word from NASA yet on the reason for the decision, but presumably it has to do with the cracks on the “stringers,” or structural ribs of the shuttle’s external tank. –Nancy Atkinson / Universe Today

That’s no asteroid! – On the evening of 21 February 1906, A. Kopff discovered asteroid 596 Scheila. It was found to have a fairly typical Main Body orbit, meaning that it lives comfortably in the middle of the Asteroid Belt between Mars and Jupiter. Beyond that, it never attracted much notice, being just one amongst billions of asteroids. –Urban Astronomer

Incredible Engineering Camera Views of the Space Shuttle in Action – Whenever there is any issue with the space shuttle, you’ll hear talk about the engineering camera footage that NASA can look at to review with a fine-tooth comb everything that took place during launch and ascent. Here is a look at some of that footage — in high resolution, and in super slow-motion — to provide a glimpse of the intricate details engineers look for. –Nancy Atkinson / Universe Today

Geminids – First Session Results – was able to spend ~40 minutes watching the Geminids so far tonight. This first session lasted from 11:43 pm (6:43 UT) till 12:28 am (7:28 UT). With a limiting magnitude of +5.4, I counted 23 meteors with 13 being Geminids and 10 being non-Geminids –Carl Hergenrother

Saturn Rings Formed From Moon Gone – Saturn’s rings are one of the most awe-inspiring features in the solar system but they may have had a violent creation 4.5 billion years ago according to a new theory advanced by astronomer Robin M.

Epic Filament Eruption - A very long solar filament that had been snaking around the Sun erupted (Dec. 6, 2010) with a flourish. STEREO (Behind) caught the action in dramatic detail in extreme ultraviolet light of Helium. It had been almost a million km long (about half a solar radius) and a prominent feature on the Sun visible over two weeks earlier before it rotated out of view. Filaments, elongated clouds of cooler gases suspended above the Sun by magnetic forces, are rather unstable and often break away from the Sun. - Courtesy of SOHO/STEREO consortium. SOHO is a project of international cooperation between ESA and NASA.

Preview of the 2010 Geminids – In the contest for best meteor shower of the year two showers are perennial candidates, the Perseids of August and next week’s Geminids. It’s usually a toss up as to which is better though over the past few years the Geminids have been better more times than not. If the sky is clear where you live, this Tuesday morning will provide one of the few nights of the year when it’s almost guaranteed that you will be able to observe a meteor after about 10-20 minutes of observing. –Carl Hergenrother
