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

A delicately violent celestial shell game – One of my favorite types of objects in space are the thin, ethereal shells of gas stars create when they die. So I was thrilled* to see this new image of one taken in exquisite detail by the Hubble Space Telescope: –Phil Plait / Bad Astronomy

X-rays From Lightning – What Superman would See – Using a custom-built camera the size of a refrigerator, Florida researchers have made the world’s first crude pictures of X-rays streaming from a stroke of lightning. –Daily Galaxy

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.

Soyuz TMA-20 Launch of Expedition 26 - A Russian Soyuz rocket launched the Expedition 26 crew to the International Space Station. The crew includes Russian cosmonaut Dmitry Kondratyev, American astronaut Catherine Coleman and from the European Space Agency Italian Paolo Nespoli.

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
