Called "Tarelka”, it was conceived during the height of the Cold War. This early secret footage shows the first scale model tests. Despite their methods being low-tech the results were remarkable. It looked impossible but the Tarelka flew. Initial tests were so successful that construction began on a full size Tarelka. Looking like a craft from another planet, it could carry up to a dozen passengers, and possibly become the new executive jet of the future. The engines are housed inside the main body. The small wings provide no lift at all, they help stabilise and steer the machine. But shortage of money from the Russian government caused work to stop on the Tarelka. A waterborne version was also tested, it was designed to travel just above the surface of the water using a cushion of air to provide lift for very little thrust. This is called ground effect, something Russian designers had used in their most unusual aircraft. The Lun-class Ekranoplan, also known as the Caspian Sea Monster, is a ground effect vehicle designed by Rostislav Evgenievich Alexeev and used by the Soviet and Russian navies from 1987 until the late 1990s. Larger than jumbo jet, this astonishing machine is powered by eight huge turbofan jet engines. It flew using the lift generated by the ground effect of its large wings when close to the surface of the water. Although they might look similar and have related technical characteristics, Ekranoplans like the Lun are not aircraft, seaplanes, hovercraft, or hydrofoils. Ground effect is a separate technology altogether. The International Maritime Organization classifies these vehicles as maritime ships.

We ve talked about the biggest stars, but what about the smallest stars? What s the smallest star you can see with your own eyes, and how small can they get?

Biggest star, hugest nebula, prettiest most talented massive galaxy, most infinite universe, and which comet came out on top in the bikini category. Blah blah blah. In an effort to balance the scales a little we’re going look at the other end of the spectrum. Today we’re talking small stars. First, I’m going to get the Gary Coleman and Emmanuel Lewis joke out of the way, so we can start talking about adorable little teeny tiny fusion factories. We get big stars when we ve got many times the mass of the Sun’s worth of hydrogen in one spot. Unsurprisingly, to get smaller stars we’ll need less hydrogen, but there’s a line we can’t cross where there’s so little, that it won’t generate the temperature and pressure at its core to ignite solar fusion. Then it’s a blob, it’s a mess. It’s clean-up in aisle Andromeda. It’s who didn t put the lid back on the jar marked H. So how small can stars get? And what’s the smallest star we know about? In the traditional sense, a star is an object that has enough mass and pressure in its core that it can ignite fusion, crushing atoms of hydrogen into helium. Fusion is exothermic, releasing energy. It’s this energy that counteracts the force of gravity pulling everything inward. That gives you the size of the star and keeps it from collapsing in on itself. By some random coincidence and fluke of nature our Sun is exactly 1 solar mass. Actually, that’s not true at all, our shame is that we use our Sun as the measuring stick for other stars. This might be the root of this size business. We’re in an endless star measuring contest, with whose is the most massive and whose has the largest circumference? So, as it turns out, you can still have fusion reactions within a star if you get all the way down to 7.5% of a solar mass. This is the version you know as a red dwarf. We haven’t had a chance to measure many red dwarf stars, but the nearest star, Proxima Centauri, has about 12.3% the mass of the Sun and measures only 200,000 kilometers across. In other words, the smallest possible red dwarf would only be about 50% larger than Jupiter. There is an important distinction, this red dwarf star would have about EIGHTY times the mass of Jupiter. I know that sounds crazy, but when you pile on more hydrogen, it doesn t make the star that much bigger. It only makes it denser as the gravity pulls the star together more and more. At the time I’m recording this video (show picture of is 2MASS J05233822-1403022), this is smallest known star at 9% the mass of the Sun, just a smidge over the smallest theoretical size. Proxima Centauri is about 12% of a solar mass, and the closest star to Earth, after the Sun. But it’s much too dim to be seen without a telescope. In fact, no red dwarfs are visible with the unaided eye. The smallest star you can see is 61 Cygni, a binary pair with one star getting only 66% the size of the Sun. It’s only 11.4 light years away, and you can just barely see it in dark skies. After that it’s Spock’s home, Epsilon Eridani, with 74% the size of the Sun, then Alpha Centauri B with 87%, and then the Sun. So, here’s your new nerd party fact. The Sun is the 4th smallest star you can see with your own eyes. All the other stars you can see are much bigger than the Sun. They’re all gigantic terrifying monsters. And in the end, our Sun is absolutely huge compared to the smallest stars out there. We here like to think of our Sun as perfectly adequate for our needs, it’s ours and all life on Earth is there because of it. It’s exactly the right size for us. So don’t you worry for one second about all those other big stars out there. What about you, how does knowing that our Sun is both big and small make you feel? Tell us in the comments below.

But underneath this flat wasteland is an intricate system of deep subterranean caves and underwater channels. The Nullarbor is consisted of the largest contiguous block of limestone in the world, and over the course of millions of years, water erosion has carved out this awe-inspiring labyrinth of caves. Not only is it amazing that such vast reserves of water lie underneath this arid landscape, but cave-divers have recently made surprising discoveries about water temperature that may hold new clues about the formation of these geological marvels. Taking refuge from the scorching Australian desert sun, Anja Taylor, Simon Pampena and Dr Derek Muller go underground to explore the largest of the Weebubbie caves.

The Yemen Option (2004): Behind the scenes of the real war against Al Qaeda. Subscribe to journeyman for more: http://www.youtube.com/subscription_center?add_user=journeymanpictures For download and more information: http://www.journeyman.tv/?lid=12674 For more than three years, a deadly yet largely unreported struggle has played out across Yemen as Washington struggles to defeat Al Qaeda. “Yemen is an important theatre that Al Qaeda has given a great deal of priority to,” states US Ambassador Edmund Hull. Large sections of the country are outside the government’s effective control and there were fears it would become a new base for Bin Laden. But the government is determined to prevent that from happening. It is spending millions buying weapons on the black market in an attempt to deny terrorists the tools of their trade. It has also collaborated in targeted assassinations and arrests although calls for prisoners to be deported to Guantanamo Bay have been rejected. However not everyone supports their actions. America fears the government is creating a new weapons market, encouraging tribesmen to import more weapons into a country already awash with arms. And many Yemenis sympathise with Bin Laden. “There is no Al Qaeda. This is just a campaign against Islam,” complains Sheik Zaid Ahmed Haider. However, despite these concerns the Yemen Option appears to be working. More than a year has now passed since the last major Al Qaeda attack in Yemen and a peace of sorts has descended on the country.

Subscribe to Naked Science - http://goo.gl/wpc2Q1 Every other Wednesday we present a new video, so join us to see the truth laid bare... Machines are evolving 10 million times faster than we are. Are you ready for robots that run our homes, watch our neighborhoods and even fight our wars? One day in the not too distant future, robots will travel to the far reaches of the universe, they will be the first to colonise new worlds. Robots will lead the way in the exploration of deep space. Robots, machines of our nightmares, or servants of man? In the 1930s film Metropolis the robot was an evil character, it represented our darkest fears. By the 1950s they had become even more sinister and powerful, but over that last few decades our opinions of robots have dramatically changed, they’ve been reinvented as the police force of the future. But can real robots match the exploits of their celluloid cousins? While the movies were creating ruthless men of steel, real robots were starting their own painful march into the world. Robots are still basic but over the past few decades they have advanced enormously. Before robots can become the masters of the universe, or even the servants of mankind, they need to accomplish one important thing, they need to move around. This 1999 documentary includes interviews with prominent roboticists and artificial intelligence specialists. Beginning with robot locomotion and historical clips of ingenious experiments from MIT s Leg Laboratory, BigDog s ancestors dynamically walk, hop, trot, and perform impressive gymnastics. To find out the best way for a robot to move around the scientists look to nature. There have been many attempts to copy nature, some successful, others less than perfect. Some of the robots discussed in this documentary : Massachusetts Institute of Technology’s Genghis II Hermes the Hexapod Micro-robot Cricket Mine Clearer Ariel Ambler the Massive Six-legged Planetary Rover Adaptive Suspension Vehicle Odetics Inc’s Odex 1 Spring Flamingo Robot Honda’s P3 Humanoid Robot Xavier from Carnegie Mellon University Robotics Cog Project at MIT’s Humanoid Robotics Group Mark Tilden s BEAM Robotics SPAWAR’s Robart 3 NASA’s Surveyor 3 Mars Rover Sojourner JPL Robotics’ Rocky 7 Rover Nomad Rover Test Vehicle Nanorover Technology
