11 February 2021 News Release

The international team of 54 astronomers were the first to pinpoint the location of a fast radio burst. Fast radio bursts (FRB) are intense pulses of radio emission that last only a fraction of a second and had confounded astronomers for more than a decade.

The origins of FRBs were a mystery because radio telescopes lacked the precision to identify where they came from.

It wasn't clear if they came from nearby stars or distant galaxies.

To resolve the mystery, the team used CSIRO’s Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope, an array of 36 antennas in Western Australia.

ASKAP is equipped with unique CSIRO-designed phase array feed receivers which widen its field of view by a factor of 30, enabling it to find bursts more rapidly. 

ASKAP was used to detect the burst and, crucially, pinpoint its location using a novel ‘live action replay’ system to pinpoint the location of the burst.

Dr Bannister, who designed ASKAP’s live action replay system said it was a great honour to receive the award which was the result of a massive team effort.

"It's thrilling to be part of cutting-edge science and technology in Australia, and to have it recognised internationally," Dr Bannister said.

Armed with the position of the burst, the team harnessed the most powerful optical telescopes in the world, including the Keck telescope in Hawaii’, ESO’s Very Large telescope and Gemini telescope in Chile to find the burst's home galaxy.

"Our results confirmed that fast radio bursts come from very distant galaxies. With the power of ASKAP we can tell which galaxy a burst came from, and also pinpoint its location within that galaxy," Dr Bannister said.

Since the discovery, the team has pinpointed many more bursts with ASKAP.

With the extra bursts, they have discovered the missing matter that makes up the cosmic web and probed the halo of an intervening galaxy. 

The AAAS Newcomb Cleveland Prize is awarded to the authors of an outstanding paper published in the journal Science by the American Association for the Advancement of Science.  

The winning paper, A single fast radio burst localized to a massive galaxy at cosmological distance, was published in Science on 9 August 2019, featuring an image of ASKAP on the front cover.

Acting CSIRO Chief Scientist Dr Sarah Pearce congratulated Dr Bannister and the team on the prestigious award and international recognition of their discovery.

"Keith’s work is an outstanding example of bringing together innovative CSIRO researchers, great collaborative astronomy partnerships and world-class Australian research infrastructure. His award is very well deserved," Dr Pearce said.

Swinburne University of Technology PhD student and fellow award recipient, Cherie Day, said it was exciting for the team to receive this recognition.

"Our team traced the source of a ‘single, millisecond-long, burst of energy in space’, to a Milky Way-type galaxy located 3.6 billion light years away," Ms Day said.

"By studying the environments around the origins of fast radio bursts, astronomers will be able to determine what causes them, solving one of the big astronomical mysteries of our generation."

In the next year, the team will commission a new burst detection system which will greatly increase the burst detection rate.  

Science is the most prestigious journal for research in the United States, and the American Association of the Advancement of Science is the world’s largest general scientific society.

The annual award recognises a paper for its quality, innovation, and wide significance.

The team comprised 54 astronomers from 21 institutes, and was co-led at CSIRO, Swinburne University of Technology, and ICRAR/Curtin, and included researchers from Australia, Chile, and the United States.  


The Australian Square Kilometre Array Pathfinder is part of the Australia Telescope National Facility which is managed by CSIRO, Australia’s national science agency. ASKAP uses the resources of the Pawsey Supercomputing Centre. Establishment of ASKAP, the Murchison Radio-astronomy Observatory and the Pawsey Supercomputing Centre are initiatives of the Australian Government, with support from the Government of Western Australia and the Science and Industry Endowment Fund.

We acknowledge the Wajarri Yamaji as the traditional owners of the Murchison Radio-astronomy Observatory site.
