The old saying of the universe being stranger than we can imagine definitely applies to a newfound exoplanet orbiting a star about 1,500 light years from Earth. Researchers using the Kepler space observatory have detected what appears to be a planet about the size of Mercury literally turning to dust. A long tail of debris — almost like a comet’s tail — is following the planet as it whirls around the star, KIC 12557548. Scientists think the planet could be evaporating under the blistering heat of the star, and that by analyzing the dust, they could decipher the history of the planet. But they better hurry. According to the team’s calculations, the planet will completely disintegrate within 100 million years.
“This might be another way in which planets are eventually doomed,” said Dan Fabrycky, a member of the Kepler Observatory science team. [click to continue…]

Saturday morning’s launch window for SpaceX’s historic test flight to the International Space Station lasts just one second. Company President Gwynne Shotwell predicted they have “better than a 50-50 shot on whether we lift off tomorrow,” she said at a press conference today, adding, “If we lift off, we’ll get to orbit.”
Shotwell and NASA officials outlined a myriad of systems and activities that have to go perfectly for the launch take place, and then it will be non-stop action for the duration of the flight to orbit and ultimately the berthing of Dragon to the ISS.
Launch is set for 08:55 UTC on May 19 (4:55 AM Eastern/1:15 AM Pacific.) Here’s a timeline of activities so you can follow along while you watch the launch: [click to continue…]
With less than a day left before SpaceX’s historic launch of the first commercial vehicle to the ISS, slated for 4:55 am EDT on Saturday, May 19, here’s a video of what will happen once the Falcon lifts off.
(Part of me really wishes that they’ll be pumping out some dramatic music when it launches!)
Researchers at Stanford University are working on solutions to the inherent difficulties of hypersonic flight — speeds of over Mach 5, or 3,000 mph (4828 km/h) — and they’ve created one amazing computer model illustrating the dynamics of air temperature variations created at those intense speeds.
This great video created from images taken by the Solar and Heliospheric Observatory (SOHO) on May 13 and 14 show Jupiter as it comes close to the Sun (from our vantage point) in a solar conjunction. But what it really looks like is the old “Space Invaders” video game, with Jupiter marching across the screen. There’s even a couple of sungrazing comets “pewpew-ing” in like the laser cannon shots in the game, and a coronal mass ejection completes the scene as an explosion (which is actually more like “Asteroids.”) For more fun, the team who created this video at the Naval Research Laboratory’s Sungrazing Comets website takes the time to show all the different objects in the scene, which amazingly includes Callisto and Ganymede, two of Jupiter’s moons. All it needs is the funky video game background music. [click to continue…]

Just look at the kind of stunning images that are buried in the archives from the Hubble Space Telescope! Here, Hubble turned its powerful wide field Advanced Camera for Surveys towards this spiral galaxy and took this close-up of its northern half. The entire galaxy, called NGC 891, stretches across 100,000 light-years and we see it exactly edge-on. Visible are filaments of dust and gas escaping the plane of the galaxy. A few foreground stars from the Milky Way shine brightly in the image, while distant elliptical galaxies can be seen in the lower right of the image.
This is just an example of the hidden gems in Hubble’s archives that have never been seen by the general public. There’s a new contest to find more — so how can you participate? [click to continue…]

In less than 48 hours, SpaceX is primed to make history and launch the first ever commercial rocket and spacecraft to the International Space Station (ISS) early Saturday morning on May 19.
Following today’s Launch Readiness Review (LRR), SpaceX was just given the official “GO” from NASA to proceed with the blastoff of the Falcon 9 at 4:55 a.m. EDT (0855 GMT) from Space Launch Complex-40 on Cape Canaveral Air Force Station in Florida. This also marks the first night time liftoff of the Falcon 9 rocket.
“Just passed final launch review with NASA”, SpaceX CEO Elon Musk tweeted this evening. “All systems [click to continue…]
As the solar eclipse on May 20th progresses, its partial and annular phases will look very similar to this eclipse on May 10, 1994. Photo by Fred Espenak/SkyandTelescope.com.
There’s a great reason to look up this weekend and hope for clear skies! On May 20-21 an annular eclipse of the Sun will be visible from a 300 kilometer-wide track that crosses eastern Asia, the northern Pacific Ocean and the western United States. An annular eclipse means the Moon will not cover the Sun completely, and so when the Moon is directly in front of the Sun, there will be a bright ring of visible light on the surrounding edges, creating a so-called ‘ring of fire.’ The eclipse begins at 20:56 UTC (16:56 EDT US time) on May 20, and ends at 02:49 UTC May 21 (22:49 on May 20 EDT).
Not in that swath? See the map below, but you may be able to see a partial eclipse if you are in Asia, the Pacific and the western two-thirds of North America. [click to continue…]

If a portion of Earth underwent a major cataclysm, how long would it take for life to recover? The 1980 eruption of Mount St. Helens is giving scientists a an unprecedented opportunity to witness a recovery from devastation, as the eruption leveled the surrounding forest, blasted away hundreds of meters of the mountain’s summit, and [...]
Researcher Jinha Lee at MIT has developed a remarkable way to interact with computers — via a programmable, intelligent and gravity-defying metal ball. The concept, called “ZeroN”, is demonstrated in the video above. Fascinating!
Located high in the mountains of Chile’s Atacama Desert, the enormous telescopes of the European Southern Observatory have been providing astronomers with unprecedented views of the night sky for 50 years. ESO’s suite of telescopes take advantage of the cold, clear air over the Atacama, which is one of the driest places on Earth. But [...]
We’ve shared the images and a previous timelapse of Earth’s northern hemisphere, but now here’s a breath-taking timelapse of the entire blue (and green!) marble as seen from Russia’s Elektro-L weather-forecasting satellite, orbiting at a geostationary height of about 36,000 km (22,300 miles). This new video was created by James Drake using some of the [...]
The crew aboard the International Space Station is now back to a compliment of six. New Expedition 31 crew members Gennady Padalka, Joe Acaba and Sergei Revin docked and have now been welcomed on board the ISS after the hatches opened Thursday at 08:10 UTC (4:10 a.m. EDT). They docked to the Poisk module at [...]
Our friend Will Gater from the BBC’s Sky At Night Magazine had the chance to get a behind-the-scenes tour of the facility that is building the Mid-Infrared Instrument on the long-awaited James Webb Space Telescope. You’ll meet MIRI inside clean room at the Rutherford Appleton Laboratory in the UK, before it’s packaged up and sent [...]
There have been only six Venus transits since the invention of the telescope in the early 17th century. It was not until 1761 that the transit of Venus on June 6th was observed as part of the first ever international scientific observation project, instigated by Edmond Halley. Astronomers across the globe viewed the transit and [...]
On the heels of a bus-sized asteroid that passed harmlessly between Earth and the orbit of the Moon on May 13, another asteroid between 4.5 and 10 meters (14-33 feet) wide will buzz by at about the same distance on May 17, 2012. Asteroid 2012 KA was discovered just today (May 16), and is projected [...]
