Australia Square Kilometre Array Pathfinder goes live as the world's quickest radio telescope
Australia's Shire of Murchison is quickly becoming a hotbed for radio telescopes. As of of Friday, the territory is operating the world's fastest radio telescope in the form of the Australia Square Kilometre Array Pathfinder (ASKAP). The 36-antenna grid's eventual use of six phased array feeds, each with 188 receivers, will let it scan a field of view 150 times larger than the moon's visible area while processing that information much faster than a typical single-pixel radio telescope feed -- CSIRO estimates that an image of the Centaurus A galaxy that would take 10,000 hours to process with rivals should take five minutes with ASKAP. Ultimately, the array should grow to 60 antennas as part of the Square Kilometer Array, which includes South Africa in its hunt for pulsars, quasars and other unique parts of the universe. Just don't get your hopes up for booking alien listening sessions anytime soon. Commissioning started virtually as soon as the ribbon was cut, and scientists have already scheduled their usage slots for the next five years. We're sure we'll get over any frustration when we see the first ASKAP results published within the next year.
IBM: 'We must build an Exascale computer before 2024' (video)
ASTRON has enlisted the help of IBM to lead a five-year, $43 million project to develop and build a supercomputer for the new Square Kilometer Array. The SKA is a $2.1 billion initiative to construct the world's largest radio telescope across a 3,000km strip of Australia or South Africa. It's hoped to be around 50 times as powerful as the dishes we currently point heavenward and will be used to examine the deepest reaches of space to learn more about the formation of the universe. When it goes live in 2024, it'll produce an Exabyte of data each day: twice as much information as there is traffic on the internet in the same period. Of course, no existing computer could handle the job, so Big Blue has a slim 12 years in which to turn nascent technologies like Nanophotonics, 3D chip stacking and phase change memory amongst others into a practical, workable Exascale computer. Its either that, or somehow daisy-chain 100 million PCs with enough power and cooling fans to keep it all working and hope for the best. If you'd like to know more, then head on past the break, although unfortunately it won't count as college credit.
