@Audio, you're really into robotics!

Mech or Electronics Engineer?

no, sadly, just a semi educated fan.

its surreal, has 9 billion pixels and a supposedly 84 million stars.....at a book like resolution the image would be 9 metres long and 7 metres tall.....if you find the smallest brightest spot (barely visible at minimal zoom) at the center and you start zooming the spot grows to almost half of the screen by the time you're done.

low bandwidth users beware!

French engineer Christophe Millot stands with his Wall-Ye prototype, a robot designed to prune vines, in the Pouilly Fuisse vineyard during a press presentation near Macon, France, on October 12, 2012. The 50 by 60 centimeter robot, with four wheels and two metal arms, has six web cameras and a GPS and can roll between grapevines, test the soil and check the grapes. With a little more training, Wall-Ye will be able to prune up to 600 vines per day, says his inventor, who has been working on the project for the past three years. (Reuters/Robert Pratta)

A European-built robot space plane could be flying in orbit before the end of the decade if the project's planning discussions, which kick off this month, come to fruition.
The spacecraft would be Europe's civilian equivalent to the U.S. Air Force's unmanned X-37B Orbital Test Vehicle, a robotic miniature space shuttle that has flown on two missions since 2010.
This European robot space plane would be an evolved version of European Space Agency’s Intermediate Experimental Vehicle (IXV), which is expected to make its first flight in 2013.

I used google-earth to get approximate co-ordinates of Kabbah by placing a marker on it.
Co-ordinates that I got are shown in picture below... Then I measured distances of it from south & north poles. I did that to confirm a claim in a video circulating on youtube, about Kabbah being at Golden-ratio point between two poles...

If I wanted results to be accurate to one decimal point, my measurements did well. But if I want it to be 3 decimal places accurate, then there was an error of just 14 Km. Still pretty negligible.

Golden Ratio of earth is city of Makkah & Kabbah give & take small error of measurement (~14 Km); the 1st place of worship appointed for mankind...

Fulfills both conditions of being at Golden Ratio i.e. a/b = (a+b)/a
& value comes out to be 1.6...

Neutron stars are compact objects that are created in the cores of massive stars during supernova explosions. The core of the star collapses, and crushes together every proton with a corresponding electron turning each electron-proton pair into a neutron. The neutrons, however, can often stop the collapse and remain as a neutron star.

Neutron stars are fascinating objects because they are the most dense objects known. They are only about 10 miles in diameter, yet they are more massive than the Sun. One sugar cube of neutron star material weighs about 100 million tons, which is about as much as a mountain.

Like their less massive counterparts, white dwarfs, the heavier a neutron star gets the smaller it gets. Imagine if a 10 pound bag of flour was smaller than a 5 pound bag!

Neutron stars can be observed occasionally, as with Puppis A above, as an extremely small and hot star within a supernova remnant. However, they are more likely to be seen when they are a pulsar or part of an X-ray binary.

This is pretty fantastic!!! Those Discovery programs really do teach you something new everyday!!!

This universe, it's enormity and vastness and magnitude is incredible if you start thinking about it, and watch the images of galaxies and stars, and compare them with our humble earth.

Through the wormhole with Morgan Freeman, How the universe works, Stephen Hawking's Grand Design, all can be downloaded via torrent or just watched on youtube (whole episodes/seasons). All have the best of contemporary scientists on them explaining the newest and most radical ideas out there. I warmly recommend, if you are interested, you wont be dissapointed.

I loved the episode about stars, where they explain in what order the elements are created inside one.
For example, iron kills a star because it absorbs energy, and the second a star creates iron it's on a death spiral which lasts a few seconds and ends in a huge explosion. All the heavier elements after iron, like gold, platinum can only be created in the heat and pressure of supernova explosion, thus explaining their rarity in the world around us.
Little pieces like that that fall into place to form a grand picture are the reasons i love this shows so much.
I also loved the comment which said "we are all made from stardust", which in essence is true, carbon atoms in our bodies were created inside some star and blown out into space in a supernova explosion.

I regularly watch those programs, among many others on Discovery and NatGeo. Very informative.

Researchers create working quantum bit in silicon, pave way for PCs of the future

By Sarah Silbert posted Sep 21st, 2012 at 12:47 AM

If you've been paying attention, you know the quantum computing revolution is coming -- and so far the world has a mini quantum network, not to mention the $10,000 D-Wave One, to show for it. Researchers from the University of Melbourne and University College, London, have now developed the "first working quantum bit based on a single atom of silicon." By measuring and manipulating the magnetic orientation, or spin, of an electron bound to a phosphorus atom embedded in a silicon chip, the scientists were able to both read and write information, forming a qubit, the basic unit of data for quantum computing.

The team used a silicon transistor, which detects the electron's spin and captures its energy when the spin's direction is "up." Once the electron is in the transistor, scientists can change its spin state any way they choose, effectively "writing" information and giving them control of the quantum bit. The next step will be combing two qubits into a logic step, with the ultimate goal being a full-fledged quantum computer capable of crunching numbers, cracking encryption codes and modeling molecules that would put even supercomputers to shame. But, you know, baby steps.

(Reuters) - A small British company with a dream of building a re-usable space plane has won an important endorsement from the European Space Agency (ESA) after completing key tests on its novel engine technology.

Reaction Engines Ltd believes its Sabre engine, which would operate like a jet engine in the atmosphere and a rocket in space, could displace rockets for space access and transform air travel by bringing any destination on Earth to no more than four hours away.

That ambition was given a boost on Wednesday by ESA, which has acted as an independent auditor on the Sabre test program.

The space plane, dubbed Skylon, only exists on paper. What the company has right now is a remarkable heat exchanger that is able to cool air sucked into the engine at high speed from 1,000 degrees Celsius to minus 150 degrees in one hundredth of a second.

This core piece of technology solves one of the constraints that limit jet engines to a top speed of about 2.5 times the speed of sound, which Reaction Engines believes it could double.

British company claims biggest engine advance since the jet

Hypergravity helping aircraft fly further

ESA research has helped to develop an aircraft-grade alloy that is twice as light as conventional nickel superalloys while offering equally good properties. The path to creating this alloy required research under all types of gravity.

Airlines are always looking for ways to save fuel by cutting down on weight without sacrificing safety. Generally, cutting weight by 1% will save up to 1.5% in fuel.

Exciting times for the aeroplane industry in the coming years it seems!

there was some project like prizeX or something when a plane was designed to carry one pilot guy to space, and the plane was as big as a common foker plane, what happened to that project?

the star which comes mighty close to black hole should have been collided with black hole due to its immense gravitational attraction and destroyed

why it didnt?

Real life thing. The center fuselage drops from the carrier plane and flies off solo.

Things dont drop directly into a black hole, they sort of spiral into it, with each orbit a bit smaller.
If you fill your kitchen sink with water and then release the plug, the water spirals into the sink, same thing happens with objects around black holes.

^^

This would be a good representation, with the star orbiting outside of this cloud that is spiraling in...
