A meteorite is essentially a solid piece of debris from a source such as an asteroid or a comet, which originates in outer space and survives its impact with the Earth's surface. It is called a meteoroid before its impact. Meteorites have traditionally been divided into three broad categories: stony meteorites are rocks, mainly composed of silicate minerals; iron meteorites that are largely composed of metallic iron-nickel; and, stony-iron meteorites that contain large amounts of both metallic and rocky material. The images above show what iron meteorites look like when cut in half. Continue reading for more cool facts.
No, this isn't a modern weapon as may have guessed from the image, but rather one from 1941, the year after France fell. It was at this time German steelmaker and arms manufacturer Friedrich Krupp A.G. company began construction on Hitler's Gustav Gun, which was four-stories tall, 155-feet-long, and weighed in at a massive 1,350 tons, while being able to shoot 10,000-pound shells from its mammoth 98-foot bore. Gustav was later employed in the Soviet Union at the siege of Sevastopol during Operation Barbarossa, where among other things, it destroyed a munitions depot buried in the bedrock under a bay.

Cloud iridescence is the occurrence of colors in a cloud similar to those seen in oil films on puddles, and is similar to irisation. It is a fairly uncommon phenomenon, most often observed in altocumulus, cirrocumulus, lenticular clouds and cirrus clouds. The colors are usually pastel, but can be very vivid. While they may look Photoshopped, all of these clouds that you're about to see are just a naturally occurring phenomena. Continue reading for more interesting facts.
During the early 1970s, American property developer Bob Gittleman had deep pockets and an unusual taste in estate cars. After wandering into Luigi Chinetti's New York Ferrari dealership and asking for "something a bit different," a Rosso Dino red Ferrari 365 GTB/4 "Daytona" coupe was shipped to Panther Westwinds in Surrey. It was converted into the world's only Daytona Shooting Brake. Continue reading for more interesting facts.
First released in 1995, the Apple Pippin was directed at the home market as "an integral part of the consumer audiovisual, stereo, and television environment," and based on the Apple Macintosh platform, in particular the Mac OS architecture. Apple built a demonstration device based on Pippin called "Pippin Power Player," and used it to demonstrate the platform at trade shows and to the media, in order to attract potential software developers and hardware manufacturers.

The VZ-9 Avrocar was basically a VTOL aircraft developed by Avro Aircraft Ltd. (Canada) as part of a top secret U.S. military project carried out in the early years of the Cold War. It's designed to use the Coanda effect to provide lift and thrust from a single "turborotor" blowing exhaust out the rim of the disk-shaped aircraft to provide anticipated VTOL-like performance. In the air, it would have resembled a flying saucer. Continue reading for more interesting facts.
Long before the B-2 Stealth Bomber, there was the Horten Ho 229 (H.IX), a German prototype fighter designed by Reimar and Walter Horten and built by Gothaer Waggonfabrik late in World War II. The aircraft was the first pure flying wing powered by jet engines. The design was a response to Hermann Goring's call for light bomber designs capable of meeting the "3x1000" requirement; namely to carry 1,000 kilograms (2,200 lb) of bombs a distance of 1,000 kilometres (620 mi) with a speed of 1,000 kilometres per hour (620 mph). Continue reading for more fascinating facts.
Lockheed Have Blue HB1001 / HB1002 was basically the code name for the company's prototype aircraft that preceded the F-117 Nighthawk. Designed by Lockheed's Skunk Works division, and tested at Groom Lake, Nevada, the Have Blue was the first fixed-wing aircraft made from an electrical engineering (rather than an aerospace engineering) perspective. The aircraft's plate-like, faceted shape was designed to deflect electromagnetic waves in directions other than that of the originating radar emitter, greatly reducing its radar cross-section. Two flyable vehicles were constructed, but both crashed during the flight-test program. Continue reading for more cool facts.
The SR-71 Blackbird completed its first (non-classified) flight on December 22, 1964, so it's only fitting to believe that the military is currently testing far more advanced aircraft, like the TR-3B Aurora. This high altitude, stealth, reconnaissance platform uses highly-pressurized mercury accelerated by nuclear energy to produce a gravity-amplifying plasma around the ship. Propulsion is provided by 3 multi-mode thrusters mounted at each corner of the triangular platform. It's capable of achieving sub-Mach 9 speeds until it reaches altitudes above 120,000 feet. Continue reading for five interesting incidents involving these black triangle UFOs.
ThrustSSC is a jet-propelled car developed by Richard Noble, Glynne Bowsher, Ron Ayers and Jeremy Bliss. It holds the World Land Speed Record, set on October 15, 1997, when it achieved a speed of 1,228 km/h (763 mph), becoming the first car to officially break the sound barrier. The car was driven by Royal Air Force fighter pilot Wing Commander Andy Green in the Black Rock Desert in the state of Nevada. Continue reading for more cool facts.
