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

Could a Human Mars Mission Be Funded Commercially? – What will it take to actually get humans to Mars? The best answer is probably money. The right amount of cold, hard cash will certainly solve a lot of problems and eliminate hurdles in sending a human mission to the Red Planet. But cash-strapped federal space agencies aren’t currently in the position to be able to direct a mission to another world – at least in the near term – and seemingly, a trip Mars is always 20-30 years off into the future. But how about a commercially funded effort? -Nancy Atkinson / Universe Today

Jupiter and Uranus at opposition

Recorded on September 27, this well-planned composite of consecutive multiple exposures captured Jupiter and Uranus in their remarkable celestial line-up accompanied by their brighter moons. The faint greenish disk of distant planet Uranus is near the upper left corner. Of the tilted planet's 5 larger moons, two can be spotted just above and left of the planet's disk. At the right side of the frame is ruling gas giant Jupiter, flanked along a line by all four of its Galilean satellites. Farthest from Jupiter is Callisto, with Europa and Io all left of the planet's disk, while Ganymede stands alone at the right. - Credit: Peter Knappert / APOD

How big is your camera? Astronomers use a 1.4 *giga*pixel camera to nab a potentially hazardous asteroid – The sky is big. Searching it for potentially hazard objects like asteroids and comets is hard. The best way to do it? A big ’scope, equipped with a BIG camera, and a wide, wide field of view. That’s just what the Panoramic Survey Telescope & Rapid Response System — PanSTARRS — brings to the table. It’s just a prototype, but it has a 1.8 meter ’scope on — wait for it, wait for it — Mount Haleakala, and it sports a 1.4 gigapixel camera. You read that right: 1.4 billion pixels. -Phil Plait / Bad Astronomy / Discovery Blogs
