NASA uses the Sun and Moon to photograph shockwave structures
High speed photography techniques have the ability to capture some pretty incredible stuff. We've seen "compressed ultrafast photography" used to track light before and NASA is showing off new pictures of shockwaves taken using the "schlieren technique." To capture images like the one above, scientists took a carefully timed shot from the ground as an aircraft passed the edge of the sun or moon at supersonic speeds. The resulting image is then further refined and cleared up using NASA derived code, but once that has been done, the result is equal parts fascinating/beautiful as evidence by the images provided by NASA.
NASA snaps photos of the ISS making its way across the sun
The image above isn't of an alien world with strange markings: it's our own sun, and those tiny marks show the International Space Station's transit across its surface as seen from Earth. NASA chief photographer Bill Ingalls captured several photos of the ISS' silhouette with our solar system's star as the background from Shenandoah National Park on September 6th. The agency then stitched five different images together to conjure up the final product. Ingalls captured photos of the station's lunar transit back in August, as well, if you'd also like to see it make its way across the moon. By the way, the spacecraft is traveling at a speed of around 5 miles per second and is fast enough to orbit our entire planet every 90 minutes! [Image credit: NASA/Bill Ingalls]
Sky Sports customers can now watch goal replays on their phones
With its live Champions League and Europa League TV rights, BT has proven to be a worthy sports broadcasting rival to Sky. The latter is now playing defence with renewed La Liga rights and a new deal with The Sun for mobile goal highlights. Sky TV customers with a Sky Sports subscription will get free access to Sun Goals, a mobile app that shows every back-of-the-net moment from the Premier League, Champions League, Europa League, FA Cup and Scottish Premiership. Of course, it's not quite the same as watching the full match on your telly, but the app should be a nice extra for sports fans nonetheless.
Mapping project catalogs Instagram sunrises from around the world
Have you noticed the wealth of sunrise and sunset photos on Instagram? Michelle Chandra certainly has, and her project offers a look at the sun's activity around the world in real time. "All Our Suns" gathers snapshots upload with either the #sunrise or #sunset hashtag, using the posts to populate a set of data-driven maps. Two of the crowdsourced cartography pieces catalog every image that's uploaded during the course of a 24-hour period -- one for sunrises and one for sunsets based on a user's location. What's more, you can click on a location marker to view the photo. A third map notes times when two people are posting at the same time, with one updating the beginning and the other observing the end of a day. The whole thing is a study on how our lives literally revolve around the sun and how social networks illustrate time as a never-ending loop.
The Big Picture: Catching an intense solar flare in action
It's no longer rare to hear reports of solar flares that could affect Earth, but seeing them in vivid detail? That's another matter. Thankfully, NASA's Solar Dynamics Observatory recently captured a high-intensity X1.8 flare (80 percent more intense than an already huge X1 flare) in action. The pretty pyrotechnics you see above represent a subset of the ultraviolet light from the eruption, while the video below shows what it looked like in other wavelengths. And the kicker? As impressive as this may be, it's far from the largest example in recent memory -- that honor goes to a mammoth X28+ flare from 2003. These ejections aren't so enjoyable when they cause havoc with communications and navigation systems, but they at least make for a good light show.
A solar storm in 2012 just barely avoided devastating our planet
If you've spent time on a beach without protection, you probably have a good idea of just how damaging the sun can be. That gigantic star that gives us life from millions of miles away can also do great harm, as Earth nearly discovered during a powerful 2012 solar storm. According to NASA, during the July 23, 2012 event, a plasma cloud left the sun traveling at 3,000 kilometers (1,864 miles) per second, passing through Earth's orbit. Our planet wasn't in its path at the time, but would have been just a week before. Instead, it hit a STEREO (Solar TErrestrial RElations Observatory) spacecraft, which was able to capture tons of relevant data. According to a study, the cloud could have caused more than $2 trillion in damage, knocking out electrical, communication and other global networks. Unfortunately, it may not be possible to prevent such a disaster, and while life would go on, it would be a far departure from what we're used to today.
The Solar Impulse 2 could fly around the world without a drop of fuel
The first time we flew around the world, it was 1924 and it took four pilots 175 days to do it. Flash forward some 90 years, and an ambitious crew in Switzerland is planning to take a stab at it themselves next year. The difference? They're aiming to do it in a plane that's powered solely by the sun.
Comet Ison may have survived its kiss with the sun (update: it didn't)
We humans can form curious attachments to non-living things, so when Comet Ison veered recklessly toward the sun, naturally we rooted for the plucky iceball. Unfortunately, scientists feared the worst after seeing it mostly vanish when it brushed past the sun's corona. Cue the heroic music, though, as new footage released early today (after the break) shows that at least part of the 1.4 mile-wide comet has emerged from the brutal encounter. It's looking a bit ragged after all that, so astronomers will have to wait a bit more to make a final call on its health. Hopefully it'll still be classed as "comet" rather than "scorched hunk of rock." Update: Sorry folks, but it looks like the comet Icarus Ison got a little too close to the sun, as it's been confirmed that the comet has broken apart and is no more. Watch its fiery destruction in the new video after the break.

Jukebox Heroes: Soul of the Ultimate Nation's soundtrack
Yes, you're seeing the header graphic correctly; Howard Shore is the powerhouse behind Soul of the Ultimate Nation's soundtrack. Yes, it's that Howard Shore -- The Lord of the Rings guy (not to mention all of his dozens of other film score projects dating back to 1979). How this smallish MMO was able to attract the likes of Mr. Shore I have no idea, but we're faced with the reality that the game did and this exists. Other than doing a little double-take when I first found this out, I'm really cool with it. I love it when well-known movie composers dip into video games, such as when Harry Gregson-Williams branched out to do several of the Metal Gear Solid titles. Shore's works are really distinctive and give SUN a sound that's far more "professional" than many of the game's contemporaries. That said, it's not the best score I've ever heard. It's quite noisy and pulls a little too much from the LotR films. Sometimes composers crib their own works (Harry Potter's music is John William's shameless ripoff of his own Home Alone soundtrack), and that's just how it goes. Let's take a look at an MMO scored by a Hollywood bigshot, shall we?
Jukebox Heroes: City of Heroes' soundtrack
Really, how could it be anything else this week? By the first of December, a major MMO influence on my life will be gone for good. We will talk about it in the past tense with wistful tones, remembering the superheroic escapades and villainous schemes. It will be given a place of honor in many of our memories, and I truly believe that City of Heroes will echo throughout the industry and community for years to come. One of those echoes is the game's score, which will endure, as does every MMO's soundtrack. When I first started playing City of Heroes in 2004, the music made a big impression on me. It painted a picture of the game's locale and atmosphere perhaps better than anything else. Heck, you could play the game with your eyes closed and know which zone you were in by the music cues. That's how integral the score was to the game. So this is my final send-off to City of Heroes: a look at the highlight from its soundtrack from the launch through Freedom. Goodbye, City of Heroes... I'm going to really miss you. I won't miss the whine from the force field bubble, but I'll miss almost everything else.
Alt-week 9.8.12: Moon farming, self powered health monitors and bringing a 50,000 year-old girl to life
Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days. Some weeks things get a little science heavy, sometimes it's a little on their weird side, and there's usually a bit of space travel involved, but these week's trend seems to be "mind-blowing." Want to grow carrots on the Moon? We got you covered. How about bringing a 50,000 year-old ancient human back to life? Sure, no biggie. Oh but what about a solar eruption that reaches some half a million miles in height. We've got the video. No, really we have. Mind blown? This is alt-week.
Researchers make unsuitable parts work as solar cells, could lead to cheaper panels
Harnessing the power of the sun is a tricky business, but even the past few weeks have seen some interesting developments in the field. In this latest installment, researchers from the Lawrence Berkeley National Laboratory and the University of California have figured out a way of making solar cells from any semiconductor, potentially reducing the cost of their production. You see, efficient solar cells require semiconductors to be chemically modified for the current they produce to flow in one direction. The process uses expensive materials and only works with a few types of semiconductors, but the team's looking at using ones which aren't normally suitable -- the magic is to apply an electrical field to them. This field requires energy, but what's consumed is said to be a tiny fraction of what the cell's capable of producing when active, and it means chemical modification isn't needed. The concept of using a field to standardize the flow of juice isn't a new one, but the team's work on the geometrical structure of the cells has made it a reality, with a couple of working prototypes to satisfy the skeptics. More of these are on the way, as their focus has shifted to which semiconductors can offer the best efficiency at the lowest cost. And when the researchers have answered that question, there's nothing left to do but get cracking on commercial production. For the full scientific explanation, hit up the links below.
Visualized: Telescope aboard suborbital NASA rocket takes clearest ever images of sun (video)
NASA has shown just what it can do with the short window of science allowed by its "sounding" or sensor-equipped suborbital rockets -- having taken the sharpest pictures ever of the sun's corona. A 460-pound telescope called the High Resolution Coronal Imager (Hi-C) was lofted for about 10 minutes into space, ample time for its mirrors to capture over 150 images of the solar fringe at 16-megapixels each, before parachuting back to earth. The scope shot exclusively in a sun-friendly high ultraviolet range and used innovative new optics consisting of an array of mirrors, allowing it to resolve the sun down to 135 miles. That bested the previous champ, NASA's own Solar Dynamics Observatory, with almost five times the magnification. For maximum effect, the space agency took advantage of an unusually high amount of solar activity to focus on a large, active sunspot. To see the results in glorious multihued HD, check the video after the break.
Researchers create incredibly thin solar cells flexible enough to wrap around a human hair
You've probably heard that the sun is strong enough to power our planet many times over, but without a practical method of harnessing that energy, there's no way to take full advantage. An incredibly thin and light solar cell could go a long way to accomplishing that on a smaller scale, however, making the latest device from researchers from the University of Austria and the University of Tokyo a fairly significant discovery. Scientists were able to create an ultra-thin solar cell that measures just 1.9 micrometers thick -- roughly one-tenth the size of the next device. Not only is the sample slim -- composed of electrodes mounted on plastic foil, rather than glass -- it's also incredibly flexible, able to be wrapped around a single strand of human hair (which, believe it or not, is nearly 20 times thicker). The scalable cell could replace batteries in lighting, display and medical applications, and may be ready to be put to use in as few as five years. There's a bounty of physical measurement and efficiency data at the source link below, so grab those reading glasses and click on past the break.

Onyx develops 330-watt 'plug-n-play' solar panel with built-in AC outlet
Onyx's new 330-watt solar panel isn't the first to offer a "plug-n-play" solution for getting power to your gadgets, but it may be the first to include a standard US power outlet, and enough output to juice up a computer, light or any other appliance (within reason) through its built-in micro inverter. "You can literally point the panel at the sun and plug an extension cord directly into the panel for immediate power," according to the Onyx PR, which you'll find in full just past the break.
Solar Ship takes to the skies powered by good deeds and sunshine (video)
The Solar Ship is a little bit airplane, a little bit blimp and all good intentions. The hybrid dirigible combines the cockpit and landing gear of a plane with the top of a blimp, the latter of which is lined with solar panels. The green vehicle can take off from and land on short runways, an ideal feature in a craft designed to deliver supplies to areas hit by natural disasters or with otherwise rough terrains. The ship will come in three sizes, and the company will be offering up more public demonstrations next year. If you can't wait that long, however, you can check out a test run after the jump.
Photovoltaic polarizers could make self-charging smartphone dreams come true
There's nothing worse than losing the charge on your iPhone at the company picnic. But fear not, you won't be stranded Twitter-less next to the potato salad if UCLA's new energy recycling LCD technology ever makes it to market. According to its inventors, the traditional LCD polarization process loses as much as 75 percent of light energy -- something that eats around 80 to 90 percent of the device's power. By using polarizing organic photovoltaic cells, however, the LCD-packing gizmo can recycle its own lost backlight energy, keeping itself charged for longer. What's really cool is these cells can recycle indoor or outdoor light as well, so you will essentially never lose a charge -- or have to speak to another human IRL again. Full PR after the break.
Sun CEO's deleted blog post to help end Oracle vs Google patent dispute?
Ever heard of estoppel? The term, sadly, does not denote a new German electronic bus service, but is rather a court-ordered way of telling companies "no backsies" on previously made public statements. It could also prove to be another nail in Oracle's patent dispute coffin, should Google's latest Wayback Machine defense hold up. Thanks to the internet's never say die policy, a 2007 post, recently deleted by Oracle, from Sun Microsystem's then CEO Jonathan Schwartz has surfaced, in which he enthusiastically endorsed Android's Java base. The public statement falls in line with the aforementioned legal doctrine, potentially contradicting new owner Oracle's patent infringement claims. Unfortunately for both parties, Judge William Alsup doesn't seem to be too cool under the collar as he's reportedly blasted each for "asking for the moon" and chiding them to "be more reasonable." A final ruling in this case is still a ways off, but in the meantime you can head to the source to read Schwartz's damning praise for yourself.
