In doing so, it's mapped three million galaxies - one million of them never seen before.
"ASKAP is applying the very latest in science and technology to age-old questions about the mysteries of the Universe and equipping astronomers around the world with new breakthroughs to solve their challenges", Dr Marshall said in a statement. The large volume of data travels faster than entire of Australia's internet traffic.
"In a time when we have access to more data than ever before, ASKAP and the supercomputers that support it are delivering unparalleled insights and wielding the tools that will underpin our data-driven future to make life better for everybody".

"ASKAP is a major technological development that puts our scientists, engineers and industry in the driver's seat to lead deep space discovery for the next generation".
Australian Minister for Industry, Science and Technology, Karen Andrews said the development proves radio astronomy is ready for a major leap forward.
ASKAP's key feature is its wide field of view, allowing it to take detailed panoramic images.
'It's really a game changer, ' said astronomer David McConnell, who led the CSIRO study of the southern sky at the Murchison Radioastronomy Observatory.
The initial results of the survey, called the Rapid ASKAP Continuum Survey (RACS), are published in the journal Publications of the Astronomical Society of Australia.

Astronomers will be able to statistically analyse large populations of galaxies the same way social scientists use information from a national census.
The telescope only needed to combine 903 images to map the entire southern sky, compared with other all-sky radio surveys that require tens of thousands of images.
The team have used the images to create a "Google Maps" of the night sky that you can interact with and use to see details of far flung parts of the known universe. "We expect to find tens of millions of new galaxies in future surveys".
The CSIRO's custom-built hardware and software processed 13.5 exabytes of raw data generated by the telescope to create the sky map.
"The Pawsey Supercomputing Centre has worked closely with CSIRO and the ASKAP team since our inception and we are proud to provide essential infrastructure that is supporting science delivering great impact", Mr. Stickells said.
These results will also be used to design projects for the Square Kilometre Array (SKA) - a massive, continent-spanning astronomy project that will become the world's biggest radio telescope.
