Murchison Widefield Array goes live, will study the sun, space junk, the early universe and more

We hope IBM's hardware is ready to chew through the feast of data it's going to receive, as the Murchison Widefield Array (MWA) radio telescope is officially open for business science. Located in the outback on the same site as the Australia SKA Pathfinder, it's one of three "precursor" programs that'll help steer future development of the extra powerful Square Kilometer Array. The MWA low-frequency telescope has plenty of work to be getting on with, and some of its first tasks include gazing into the sun to observe solar flares, storms and other activity, as well as scanning the Milky Way for the likes of "black holes and exploding stars." It'll also look into the tracking of hazardous space garbage using FM radio waves that are lost to the void, and explore the early life of the universe as far back as 13 billion years. According to Curtin University's Professor Tingay, the MWA's commendable work ethic (read: data quality) means we could see initial results from some of these projects "in as little as three months' time."

Australia Square Kilometre Array Pathfinder goes live as the world’s quickest radio telescope

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.

Radio astronomy pioneer Sir Bernard Lovell dies at 98

Radio astronomy pioneer Sir Bernard Lovell dies at 98

Astronomy just lost one of its vanguards, as Sir Bernard Lovell has died at 98. The UK-born scientist was best known as a cornerstone of radio telescope development. While he wasn't the first to leap into the field, he established the University of Manchester's Jodrell Bank Observatory to study cosmic rays in 1945 and organized the construction of what would ultimately be called the Lovell Telescope -- a radio telescope so large and useful that it's still the third-largest steerable example in the world, 55 years after it was first put into action. His work helped track some of the earliest spacecraft and was instrumental in confirming the first discovered pulsars and quasars. On top of his most conspicuous achievements, Sir Lovell played an important role in developing airborne radar during World War II and was lauded for having scientific curiosity long after he hung up his Jodrell director's hat in 1980. Science will be poorer without him.

IBM cluster powers Murchison Widefield Array’s radio telescope, answers mysteries of the universe faster than ever (video)

IBM cluster powers Murchison Widefield Array's radio telescope, answers mysteries of the universe faster than ever video

Radio telescope operators have as much of a problem coping with the avalanche of data as getting that information in the first place. The Victoria University of Wellington is all too aware and is leaning on IBM for a powerful (if very tongue-tying) iDataPlex dx360 M3 compute cluster to sift through the deluge at the upcoming Murchison Widefield Array. Combined, the 4,096 array antennas probing deep space and solar atmospherics will have the Xeon-based cluster tackling signal data to the tune of 8GB per second, and about 50TB per day -- that's a Nexus 7's worth of astronomy faster than you can sneeze, folks. A 10Gbps network connection will feed the results to Perth to save scientists a roughly 435-mile trek. Construction is still in mid-stride, but the $51 million Australian ($52.2 million US) being spent on the Murchison array may be worthwhile if it helps solve the riddles of star formation and solar flares.

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.
