The SKA’s  15m-dishes, which will detect electromagnetic radiation emitted by  objects in space, will be the most sensitive ever built - able to detect  an airport radar on a planet 50 light years  away.These  dishes will be complemented by low and medium frequency aperture  arrays, which provide a large field of view and are capable of observing  more than one part of the sky at once.<img src="http://i.imgur.com/EYWrD.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Medium frequency aperture arrays: These are capable of scanning more than one part of the sky at once<img src="http://i.imgur.com/myeIl.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Space-aged kit: An artist's impression of SKA's  low-frequency aperture arrays<img src="http://i.imgur.com/p3t2r.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" />Good spread: This graphic illustrates how the dishes and apertures will be arranged as they scan the heavens<img src="http://i.imgur.com/J8pbm.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /> Heavens above: SKA will peer deep into space telling us about black  holes, how stars are born and if there is alien life out there The volume of data produced from the dishes will be mind-boggling –  many Petabits per second, or around 100 times the current global  internet traffic and enough to fill 15million 64GB iPods every day.It will be carried on enough optical fibre cable of such quantity that it could be wrapped twice around the world.And a super-computer capable of one million trillion operations per second will have to be built to analyse it - that's 1000 times faster than the most powerful we have  today.A  lot of brainpower will be needed to build the SKA and there are 67  organisations in 20 countries contributing to its design and  manufacture.As yet, a location for it hasn’t been decided, but Southern Africa, Australia and New Zealand are all in the reckoning.They  all offer areas with ideal conditions for telescopes, which must be  well clear of electronic interference, such as that generated by mobile  phones.It’s hoped that construction will begin in 2016, with the dishes coming online eight years later. A prototype of SKA called KAT-7, which consists of seven 16-metre dishes, is undergoing testing in South Africa's Karoo desert.<img src="http://i.imgur.com/r9Vfs.jpg" alt="" class="fr-fic fr-dii fr-draggable " style="" /></blockquote>
