Δημοσιεύτηκε στις 7 Νοε 2014
The surface of the sun from October 14th to 30th, 2014, showing sunspot AR 2192, the largest sunspot of the last two solar cycles (22 years). During this time sunspot AR 2191 produced six X-class and four M-class solar flares. The animation shows the sun in the ultraviolet 304 ångström wavelength, and plays at a rate of 52.5 minutes per second. It is composed of more than 17,000 images, 72 GB of data produced by the solar dynamics observatory (http://sdo.gsfc.nasa.gov/). This animation has be rendered in 4K, and resized to the Youtube maximum resolution of 3840×2160. The animation has been rotated 180 degrees so that south is 'up'. The audio is the "heartbeat" of the sun, processed from SOHO HMI data by Alexander G. Kosovichev. Image processing and animation by James Tyrwhitt-Drake.

► Flying Car - AeroMobil 3.0 demonstration

Δημοσιεύτηκε στις 7 Νοε 2014
An advanced prototype of the flying roadster AeroMobil 3.0 was unveiled in Vienna during the Pioneers Festival that celebrates entrepreneurship, technology and innovation.
A beautifully designed fully functional prototype of a flying car developed and built in only 10 months.

The current flying car prototype AeroMobil 3.0 incorporates significant improvements and upgrades to the AeroMobil 2.5. It is now finalized and is being tested in real flight conditions since October 2014. Initially certified by the Slovak Federation of Ultra-Light Flying, it now entered a regular flight-testing program.
The AeroMobil 3.0 prototype is very close to the final product. It is predominantly built from the same materials as the final product, such as advanced composite materials for the body shell, wings, and wheels. It also contains all the main features that will be incorporated into the final product, such as avionics equipment, autopilot and an advanced parachute deployment system.
Currently the AeroMobil 3.0 prototype will serve two main purposes. First, it will be used to test and improve the final performance, features, and characteristics. Second, it will be used for initial marketing purposes, including presentations at major trade shows.

AeroMobil was designed in a way to fit into existing road infrastructure – its size is comparable to a limousineor a large luxury sedan. It has low maintenance costs and can be parked in regular parking slots in cities. It uses standard gasoline instead of kerosene, and it can therefore be fuelled at a regular gas stations.
AeroMobil also implements a number of other advanced technologies, such as a variable angle of attack of the wings, which significantly boosts the efficiency of take-off and shortens the take-off requirements, and sturdy suspension, which enables take-off and landing at relatively rough terrain.

F-35C Lightning II carrier variant Joint Strike Fighters launch from and land aboard the aircraft carrier USS Nimitz (CVN 68) off the coast of San Diego. The launches and recoveries are part of initial at-sea Developmental Testing I (DT-I) for the F-35C, which commenced Nov. 3 and is expected to last two weeks. The F-35C is the carrier variant (CV) of the F-35 Lightning II Joint Strike Fighter designed for the U.S. Navy as a first-day-of-war, survivable strike fighter complement to the F/A-18E/F Super Hornet.
