New footage from San Francisco firm's SkySat-1 reveals planes taking off in Beijing - and it is available to the public. Footage shows cars are moving on roads and vessels travelling through shipping lanes - all from a satellite positioned 600 kms above the planet. ...read

The image shows how the Iberian coastline is heavily populated with Valencia and Barcelona prominent at the bottom right of the photo.
Saturn's dazzling rings are pictured in unprecedented detail - and its 'Death Star' is lurking nearby (if you look hard enough!)
The space agency’s Cassini probe took the image on October 22, 2013, when it was about 1.6 million miles (2.6 million km) from Saturn. he planet’s scarred moon Mimas, also known as the Death Star, is visible as a pin prick of light at the bottom right. The image also shows the mysterious ‘spokes’ in Saturn's B ring, just to the right of centre. What creates these spokes is still a mystery, but scientists do know that spokes no longer appear when the sun is higher in Saturn's sky.
Death of an asteroid: Hubble captures enormous space rock self-destructing on film for the first time
The asteroid, named P/2013 R3, smashed into ten smaller pieces over a period of months. Some fragments are expected to eventually reach Earth's atmosphere. Scientists said the break-up was probably the result of the subtle effect of sunlight over many years causing the asteroid to spin at a slowly increasing rate until it became unstable and ruptured. This phenomenon, known as the YORP effect, has been debated by scientists, but never previously reliably observed.

The three-armed drummer with superhuman skills: Robot prosthesis transforms amputee into an incredible 'cyborg' beat machine
The robot arm, created for drummer Jason Barnes from Atlanta, is able to listen to the music being played and improvise its own beat. The prosthesis controls two drumsticks. The first stick is controlled both physically by the musicians’ arms and electronically using muscle sensors. The other stick can react to the music being played. ‘I’ll bet a lot of metal drummers might be jealous of what I can do now,' Mr Barnes said.
The room where the internet was born: UCLA opens up the office where the first message was sent - and reveal it crashed after sending just TWO letters
3420 Boelter Hall at UCLA (top left) saw the first the first Arapanet transmission with Stanford on October 29, 1969 (bottom right). The first message was supposed to be 'log in', but their first success also spelled their first failure – the system crashed after the 'L' and 'O' were transmitted on a teletype (bottom right) by Leonard Kleinrock (top right) and his team
The giant floating robotic fish farm set to revolutionise salmon production
Each of the 5,600 tonne, 670-metre-high steel rigs developed by a Norwegian fishing firm can house eight times as many salmon as conventional cages. They have a 245 square metre pen for the salmon, space in the offices above for 600 tonnes of feed, and accommodation for up to four people - although they can be operated remotely.

SMARTPHONES? IT'S YOUR CALL
The ultimate non-iPhone smartphone guide...
Talk time: 9.5hr (7hr playback, 55hr music)
Spec: 3.7in (800x480 pixels) AMOLED screen, 16GB, 1.4GHz Windows Mango, 8MP camera, 720p HD video
Verdict: This combination works wonderfully. It's a pleasure to use and Nokia's Drive GPS app is impressive. We've rated these iPhone alternatives from Ace down to Five - and the Nokia is at the head of the pack.
Talk time: 8.5hr
Spec: Android Ice Cream Sandwich OS, 1.2GHz dual-core processor, 4.65in (720x1,280) AMOLED screen, 5MP camera, 1080p video, 16GB memory
Verdict: It's got a beautiful screen, intuitive operating system and cool features like face-recognition security, but battery life doesn't quite match the hype.
Talk time: 6hr 50min
Spec: Windows Phone 7.5 Mango, 1.5GHz, 4.7in (480x800) screen, 16GB, 8MP camera, 720p HD video
Verdict: The Titan is slim, light and has the largest screen on any Windows device. Shame they didn't give it better screen resolution.
Talk time: 4hr
Spec: Android 2.3 Gingerbread, 1 GHz, 4.3in (800x480) screen, 8MP camera, 1080p HD video, 8GB memory
Verdict: The sharp lines and thin bezel give a professional look while the monochrome interface screams class. One for the fashionistas.
Talk time: 5hr 20min
Spec: BlackBerry 7 OS, 1 GHz, 2.45in (480x360) screen, 5MP camera, VGA video, 8GB memory
Verdict: Beautifully made and with a battery life most handsets would kill for, but the OS is limiting and even with its touch screen it can't compete.
Talk time: 7hr 35min
Spec: Android 2.3.4 Gingerbread, 1.4GHz, 4.2in (854x480) screen, 1GB internal, 8GB MicroSD memory (included), 8.1MP camera, 720p HD video
Verdict: Motorola take note, this is how you do slim and sexy. The camera is let down by a poor menu and awful shutter button, but Sony's social media widget 'Timescale' is a time-saving stroke of genius.
Talk time: 10hr
Spec: Android 2.3.5 Gingerbread, dual-core 1.2 GHz processor, 4.3in Super AMOLED (540x960) screen, 8MP camera, Full HD video, 16GB
Verdict: Light and impossibly thin, but even with its rigid Kevlar frame it feels limp and lopsided in the hand. Shame, as the screen is exceptional and the interface is bursting with neat tricks including the ability to resize the icons you use most.
Talk time: 4hr 30min
Spec: Android 2.3 Gingerbread, 800MHz processor, 3.5in (800x480) screen, 5MP camera, 512 MB internal memory, 2GB microSD card (included)
Verdict: Never going to induce envy but if you want smartphone functionality without budget busting it's hard to fault. Navigation is intuitive; battery life excellent.
Talk time: 4hr
Spec: Android 2.3 Gingerbread OS, 3.5in (800x480) screen, 5MP camera, 800MHz processor, 512MB memory, 2GB microUSB card, GPS
Verdict: The Vivacity is essentially the San Francisco II with iPhone looks, and while it lacks the fluidity of its more expensive cousins, you can get app-happy on a budget.
Talk time: 4hr 30min
Spec: Android 2.2 Froyo, 2.8in (240x320) screen, 2MP camera, 130MB memory, 2GB microSD card
Verdict: It might be cheap, small and pocketable but as a smartphone it's cramped, slow and the minuscule memory limits the number of apps.
Could this wallpaper prove that Napoleon was MURDERED? Décor that might have been laced with arsenic goes up for auction
The French emperor (inset) mysteriously died while in British custody on the South Atlantic island of St Helena on May 5, 1821 at the age of 51. Since his death, it has been suggested that he died from cancer or was poisoned by British soldiers. A third theory says he died after inhaling toxic vapours from wallpaper (sample, pictured) which was laced with arsenic. It is thought there will be a lot of interest in a piece of the wallpaper covering a scrapbook (inset bottom) when it goes on sale at an auction in Shropshire on March 18.
Forget Waterworld - this amazing floating city could use freshwater from melting icebergs to generate power and grow its own food
Designed by students in Paris, the Arctic Harvester would use nutrient-rich water from icebergs to grow crops and provide power to the 800 people on board. Arranged in a circular form (left), the icebergs would be delivered into its central bay (top right). An osmotic system, which generates power from a combination of saltwater and freshwater, would generate energy, along with solar panels. The bottom right image shows a view of the bay from inside the floating city.
