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

Breaking News: A newly discovered asteroid, designated 2010 WA, is projected to fly by at the altitude of roughly 39,000 km around 3:45 UT tomorrow, November 17. The object was discovered by Catalina Sky Survey telescope at Mount Lemmon last night (Nov. 16). MPEC-2010W03

Japan probe collected particles from Itokawa asteroid – Japanese scientists have confirmed that particles found inside the Hayabusa probe after its seven-year space trip are from the asteroid Itokawa. –Jonathan Amos / BBC News

So is Pluto a planet after all? – The news last week that Eris might actually be a tiny bit smaller than Pluto led to the inevitable question: doesn’t this mean that Pluto should be a planet, after all? The simple obvious answer to this question is no –Mike Brown

Sunset on Mars – I know, it may not look like much, but think about what you’re seeing: a sunset on another world. And those images were taken by a robotic probe that took years to design and build, months to travel the hundreds of millions of kilometers to get to Mars, a harrowing few minutes to descend on a breath of fire through the thin air to land on the surface, and then nearly seven years to travel the landscape long, long past its design specifications. –Phil Plait / Bad Astronomy

Chandra Finds Youngest Nearby Black Hole – Astronomers using NASA’s Chandra X-ray Observatory have found evidence of the youngest black hole known to exist in our cosmic neighborhood. The 30-year-old black hole provides a unique opportunity to watch this type of object develop from infancy. –NASA
