Latest ASKAP News


Commissioning News, May 2018

The construction of ASKAP is nearing completion with 24 antennas having been handed over for commissioning and integration into the array. The remaining antennas await installation of their digital processing systems, scheduled to occur mid-2018. Delivery of ASKAP's capabilities to the astronomical community will happen in staged "array releases" of increasing scope.

The next major milestone will be array release 3, which consists of 18 antennas, 288 MHz of bandwidth and for the first time, the ability to exchange bandwidth for frequency resolution (known as "zoom modes" within the community). Array release 3 will also offer the longest baselines (and therefore highest image resolution) to astronomers for the first time. Zoom modes will enable studies of neutral Hydrogen and other spectral lines within the Milky Way, providing a more detailed picture of gas dynamics and stellar feedback.

Array release 4 is the full ASKAP system with 36 antennas and this is currently scheduled for release on a shared-risk basis in early 2019.

One of the major challenges faced by ASKAP is the desire to begin survey operations early in the life cycle of the telescope. Most radio telescopes spend the first few years of operation conducting smaller-scale projects while the system reaches the level of maturity required to conduct large-scale all-sky surveys (which represent a major investment in time).

ASKAP will be expected to perform large-scale surveys very early in its operational lifespan, requiring particular attention to detail during commissioning. To gain experience with survey operations, we intend to conduct a series of "pilot surveys", which will be designed to investigate specific targets that provide a good test of the telescope's characteristics (sensitivity, dynamic range, calibration stability, etc.).

At a recent meeting of ASKAP's science team principal investigators we described the planned array release schedule including readiness to take 36-antenna survey data in some form in early 2019.  There was also discussion of plans to review the original survey proposals. Given the time that has passed since the original call for proposals there was consensus that a reassessment of the survey scientific goals and technical feasibility is required at some point in the near future, though the timing of this process is still under consideration.

The scientific climate has changed significantly (particularly in the field of transient detection) during this time. As we move towards array release 4, it will be important to maintain close ties with the science teams and we expect to host more of these discussions every few months. This will allow us to prioritise development of key systems (such as the science data pipeline software) based on up-to-date science requirements

Pawsey funding announcement is good news for ASKAP, April 2018

The federal Government has just announced the Pawsey Supercomputing Centre will receive $70 million to procure a replacement for its flagship supercomputer, Magnus, as well as the real-time supercomputer, Galaxy. Both systems, are close to the end of their operational lives. Magnus, a Cray XC40, is considered to be one of the most advanced supercomputers in the southern hemisphere. Galaxy is dedicated to the operational requirements of the SKA pathfinder telescopes, ASKAP and MWA.

Chair of the Pawsey Supercomputing Centre, Mr John Langoulant AO, said this will strengthen Australia’s position in the global research environment and enable Australia to stay globally competitive. The procurement process for the capital refresh will commence immediately with the intention of new infrastructure being available from 2019.

What does this mean for ASKAP?

This will be a vast improvement on the power and processing capability of Galaxy. It will provide more disc space to store the data sets that are coming in from commissioning observations, which are getting bigger and bigger all the time, as more antennas come online.

ASKAP’s current data rates are in the order of about 1 terabyte per hour, that’s generated by observations using 12 of the 36 antennas. This number will increase to about 1.5 terabytes per hour in the coming weeks, when 18 antennas are in operation. The full data rate, when all 36 ASKAP antennas are operational, is more like 10 terabytes per hour. The data is processed on Galaxy, so this refresh will put us in a great position to maximise science from ASKAP as we get 36 antennas on line.

Information about Pawsey

Pawsey is a collaboration hub. The Centre currently serves more than 1,500 active researchers from across Australia, involved in more than 150 supercomputing projects to deliver scientific outcomes. Nine Australian Research Centres of Excellence benefit from Pawsey’s infrastructure and expertise.

This investment will enable Pawsey to continue to drive innovation and accelerate discoveries in medical science, engineering, geoscience, marine science, chemistry, food, agriculture and more.

Awesome ASKAP Image, December 2017
ASKAP’s been 'moonlighting' in the media recently and featuring on the CSIRO Blog with the release of an awesome image of the Small Magellanic Cloud (SMC). Highlighting ASKAP’s unrivalled speed and detail, the last time the SMC was imaged by a radio telescope, it took 320 pointings (by ATCA). In contrast, this new image was made in one shot – over three nights – using only 16 of ASKAP’s 36 receivers. Data from Parkes was added to pick up faint details. The new image reveals more gas around the edges of the galaxy and these features are more than three times smaller than we’ve seen before - enabling examination of the detailed interaction of the SMC and its neighbouring galaxies. The SMC is one of our nearest and smallest galactic neighbours - the bad news for this dwarf galaxy is that it's on track to be (eventually) gobbled up by the Milky Way - that's quite an appetite!

Astronomical excursion for Pia Wajarri School, November 2017   
As part of the Indigenous Land Use Agreement (ILUA) between the Australian Government and the traditional owners of the Murchison Radio astronomy Observatory (MRO) site, CSIRO Astronomy and Space Science staff members Rob Hollow, Dr Shi Dai and Dr Zoe Taylor travelled to the remote Pia Wajarri Remote Community School and took the students and teachers on tour of ASKAP. Shi, a young astronomer, talked to the students about his career in astronomy and about how stars and galaxies form in the Universe.  Zoe talked about why she’s interested in software engineering and inspired the students talking about her work on the Australian SKA Pathfinder telescope. Zoe also introduced coding to the students with Spheros (the programmable robot). Zoe and Rob used the Sphero robots to demonstrate coding and demonstarted how to write simple programs. The fun really "took-off" when Rob set up the alka-seltzer water rockets and a challenge to see whose could fly theirs the furthest. At the MRO, the students and teachers toured ASKAP and learnt about how the radio dish antennas operate. At the control building, CSIRO’s James Hannah was working on electronics boards and gave the young locals a close-up look at these high-tech components. They headed back to Pia via the MWA and the AAVS1 test array, where they heard all about the world’s biggest telescope, the Square Kilometre Array!

CSIRO Astronomy and Space Science (CASS) completes mechanical construction of ASKAP's 36 dish array in WA, November 2017
On Tuesday 21 November, our 36th phased array feed (PAF) receiver was installed on AK #29, marking the completion of the installation of all receivers for ASKAP-36! The innovative PAF receivers on each of ASKAP's 36 antennas enable a large simultaneous field of view at 1.4 GHz. Sixteen of the antennas also have complete digital back-end systems, enabling the delivering of exciting early science results. We expect the full 36-dish array to come online progressively throughout 2018.

Powering up in the outback, September 2017
Ah the Australian outback. Red dirt, bounding kangaroos and wide open spaces that seem to go on forever. Sure it’s a great place to explore that little slice of untouched Australia but it’s also the perfect place for our radio telescopes to explore the unknown Universe. It’s because of our southern hemisphere location and our ability to manage large, complex facilities with a high degree of reliability, that we’ve been involved in some iconic events, including the Moon landing, and the last hurrah of Cassini as it plummeted into Saturn.

Now we’re building a new generation of radio astronomy technology with ASKAP. ASKAP is made up of 36 dish antennas, working together as a single instrument. Each antenna is fitted with a special ‘camera’, the CSIRO-designed phased-array feed, that is made up of 188 individual receivers. You can think of it as a bit like a wide-angle lens allowing you to see more through a single viewpoint. ASKAP is the fastest radio telescope in the world for surveying the sky, taking panoramic snapshots more than 100 times the size of the full Moon. To take these snapshots, we had to build ASKAP in a remote location to reduce the chance of radio interference. Radio telescopes use extremely sensitive radio receivers designed to measure the very faint radio signals arriving from astronomical sources in space. But radio interference is part and parcel of modern society. Things like mobile phones, microwaves, radio and TV transmissions all use radio frequencies to work and therefore interrupt our view of the Universe. 

The problem with a nice, remote, radio-quiet place is how to power it. Poles and wires just aren’t built in these areas, so most remote radio astronomy sites rely on diesel power. But diesel can get expensive and comes with a sizeable carbon footprint. Ah huh! Renewable energy like solar or wind! Yes but, getting the most out of renewables means bringing in a battery to store the power, and battery electronics interfere with our radio silence too. But we’re CSIRO. We couldn’t let this challenge get the better of us! So we decided to see if any Australian companies could help us build a battery that could store the power generated by solar panels, but still meet our radio-quiet requirements and not interfere with the operation of our telescopes.

Field of solar panels in the West Australian outback

Our battery with a shield ensures we can make the most of the power captured from our 5280 solar panels.

Enter Energy Made Clean, or EMC, a small business based in Perth. Working closely with our engineers and scientists, EMC has built the world’s first solar storage system to run a remote radio astronomy site. They built a battery with a shield to ensure it doesn’t interfere with our radio telescopes, allowing us to store the power captured from our 5280 solar panels during the day and use it into the night, switching seamlessly between solar and diesel power as a backup. 

Our solar and lithium-ion battery combo has the potential to power more than 400 homes and save between 1700 and 2200 tonnes of carbon emissions per year. EMC’s growth through this project has now set them up to be competitive for global energy infrastructure tenders.

EMC grew from 10 to 50 employees and has already received a number of enquiries about shielding renewable generation systems. They’ve grown significantly in their company skill set – a very necessary one for them to develop and become a bigger company taking on more complex projects. John Davidson from EMC said “the engineering expertise we have developed will carry us into future projects – we are at world-class level now and able to deliver similar projects.” “The proactive approach by CSIRO in identifying how they can collaborate and allow SMEs to grow is refreshing,” he said. The ASKAP telescope is a precursor to an even bigger global project called the Square Kilometre Array (SKA).

The SKA is going to need three times more power than the ASKAP telescope so this setup might also allow us to power it with renewable energy too. Now we can get back to exploring the Universe.

A shipping container customised to shield the battery

The solution for storing our battery was to house all the high power electrical equipment in metallic shielded enclosures.

Ernie Dingo visits our outback astronomy observatory – in his beloved backyard, August 2017
We searched far and wide for a place in Australia to build a world class radio astronomy observatory. The location had to be remote and far from man-made radio interference, to ensure quietness for these instruments to detect radio waves travelling from billions of light years away. It also needed to be somewhere relatively accessible for construction and observatory management. We found the perfect spot in the Murchison area of Western Australia, 700 kilometres northeast of Perth and in traditional Wajarri Yamatji country. It’s now home to our new Australian Square Kilometre Array Pathfinder telescope (ASKAP) and the Murchison Widefield Array telescope (MWA) led by Curtin University. It’s also a future site for the Square Kilometre Array (SKA) – the world’s largest and most ambitious international radio astronomy project ever realised. Wajarri Yamatji Elder and Australian TV personality Ernie Dingo was passing by recently, so we invited him in for a tour and a chat about the Murchison Radio-astronomy Observatory (MRO), situated on his ancestral and beloved homeland.

“This is where I come from [the Murchison], my home soil and I’m really glad the MRO is here to allow scientific visitors on Wajarri Yamatji ground. We are proud of our corner of the world, there are lots of secrets in the mid-west and it’s wonderful that this land has been adopted by scientists to unlock the secrets of the Universe.”

Telescopes at the MRO will provide astronomers with the capability to answer fundamental questions about our Universe, such as the nature of cosmic magnetism and the evolution and formation of galaxies. Ernie is excited by the potential the facility brings to the local and global community; “It will inspire young people and further this part of the world. The antennas have a relatively small impact on the land, which is good from my point of view,” he said. Many partners have come together to create an Indigenous Land Use Agreement (ILUA) for the MRO to operate, and to ensure educational, social and economic benefits flow to the Wajarri Yamatji. The ILUA includes a cadetship program that runs for the life of the telescopes and our staff visit the remote Pia Community School as part of a mentoring program. We’ve co-created resources on Wajarri culture and the MRO. A new ILUA for the SKA will expand on these benefits. ASKAP’s 36 individual dish antennas spread out across a six kilometre area. In contrast to the rustic colours of the Australian outback, they’re bright white but Ernie says they fit in the landscape, like part of the furniture! “This is wildflower country and they’re like beautiful giant white wildflowers growing up out of the earth”. On his visit Ernie finds bushfood growing under the telescope and although he recognises the site is generally closed to visitors for radio quiet purposes. “I hope the scientists get a chance to stop and smell the flowers – there’s plenty of bush food out here and it’s the only place in the world where the wreath flower grows.”

CSIRO acknowledges the Wajarri Yamatji as the traditional custodians of the MRO site and gratefully acknowledge the important role the Wajarri Yamatji have played in enabling Australia to secure the rights to co-host the SKA.
