Stuart Atkinson, an amateur astronomer from Kendal, UK, discovered this incredible cliff on Comet 67P while studying an image beamed back by the Rosetta probe. He found the location on notes by the European Space Agency, which said the picture - pieced together from four taken 12 miles from the comet on December 10 - measured 1.8 by 1.6 miles from end to end.

At 00.49 GMT on April 12th, a huge sunspot released a massive X4.9-class flare - the largest of 2014. Thankfully, it appeared on the sun's southeastern limb, and did not impact satellites or radio communication. Spaceweather.com said: "Radio emissions from shock waves at the leading edge of the cornoal mass ejection (CME) suggest an expansion velocity near 2000 km/s or 4.4 million mph. If such a fast-moving cloud did strike Earth, the resulting geomagnetic storms could be severe. However, because its trajectory is so far off the sun-Earth line, the CME will deliver a glancing blow, at best." Continue reading for more.
Most Christmas trees are purchased from a vendor / store, this one was made from 5,000 pieces of firewood, and located at a a public square in Budapest, Hungary. Workers spent 5-days building the tree, using rappelling gear as they neared the top, to stack sawed logs of tapering sizes within the cone-shaped, 35-foot wooden frame.

The F/A-18 is nothing new, but this rarely seen image of it approaching the sound barrier is. The white halo formed by condensed water droplets is thought to result from an increase in air pressure around the aircraft at transonic speeds. In dry air at 20 °C (68 °F), the sound barrier is reached when an object moves at a speed of 343 metres per second (1,125 ft/s). The term came into use in this sense during World War II, when a number of aircraft started to encounter the effects of compressibility, a number of several unrelated aerodynamic effects that "struck" their aircraft like an impediment to further acceleration.

ZheJiang University researchers in China demonstrate graphene aerogel by placing the extremely light substance on a flower. Professor Gao Chao created this by using a new freeze-drying method that involved freeze-drying solutions of carbon nanotubes and graphene to form a carbon sponge that can be arbitrarily adjusted to any shape. The final result is a very strong and extremely elastic material that can also absorb up to 900 times its own weight in oil - one gram of aerogel can absorb up to 68.8 grams of organics per second, making it perfect for mopping up oil spills at sea.

These are not from alien worlds, just opals mined here on Earth. The opal is basically a hydrated amorphous form of silica, and its water content may range from 3% - 21%. They are deposited at a relatively low temperature and may occur in the fissures of almost any kind of rock, being most commonly found with limonite, sandstone, rhyolite, marl and basalt. Australia produces 97% of the world's supply, and the internal structure of precious opal makes it diffract light; depending on the conditions in which it formed, it can take on many colors.

The 2015 Ford Mustang RTR might not be the first tuned Mustang to hit the streets, but it's definitely no slouch. Professional drifter Vaughn Gittin's RTR brand partnered with Ford to create this special edition Mustang, powered by a 5.0-liter supercharged V8 engine that generates 725-horsepower. Other upgrades include an adjustable suspension, stiffer anti-roll bars, and a set of Brembo brakes for extreme stopping power. Continue reading to see this beast drift around SEMA 2014, more pictures and additional information.
Let's face it, being on active duty in a battle zone can be stressful to say the least, and humor is one channel some soldiers use to calm themselves. Whether it positioning themselves in the perfect spot to make it appear as if they're eating soldiers climbing down from a helicopter, or just playing Quiditch, you'll find them here.

Star Wars Episode VI: Return of the Jedi was first released in theaters on May 25, 1983, directed by Richard Marquand and written by George Lucas and Lawrence Kasdan, with Lucas as executive producer. It was the first film to use THX technology, and is set one year after The Empire Strikes Back. Filming took place in England, California, and Arizona from January to March 1982, with Lucas handling second unit work. Strict secrecy surrounded the production and the film used the working title Blue Harvest to prevent price gouging. The film grossed over $475 million worldwide, with several home video and theatrical releases and revisions to the film following over the next 20 years.
