Citizen also being an innovative and effective method to scientists will conduct real astronomical engage the public in science through astronomy. analysis of images and data, and gain a practical understanding of modern astronomy and how Off the back of the success of theSkyNet, astronomers study the distant Universe. ICRAR partnered with ABC Science in 2015 to develop Galaxy Explorer. This active This expanded Galaxy Explorer program has citizen science program allows anyone to help the capacity to reach tens of thousands of astronomers classify galaxies up to four billion global citizen scientists, and engage them in the light years away. Volunteers are provided with process of analysing Australian astronomical a quick tutorial, before taking a trip to some data. The results will be essential for the success of the furthest reaches of the Universe. Galaxy of the multimillion-dollar WAVES project, led Explorer complements the work of theSkyNet, from ICRAR. and provides data to ICRAR astronomers working on the Galaxy And Mass Assembly This survey is the largest ever (GAMA) survey. experiment on the evolution Originally developed for National Science of galaxies, and the work of Week, Galaxy Explorer has grown to become a powerful ongoing citizen science platform. The citizen scientists will have a project’s volunteers have successfully helped lasting impact in the field of ICRAR’s astronomers classify and measure the properties of more than 210,000 galaxies. astronomy.

The Centre is engaging the wider community the Universe has ever seen, the Wide Area in real research through three distinct projects; Galaxy Explorer, theSkyNet and Radio Galaxy Zoo.

ICRAR is passionate about giving citizen almost 20,000 computers around the world are scientists the chance to make a genuine contributing to the project. This adds up to a contribution to discovering more about the distributed network capable of performing more Universe. The Centre’s citizen science journey than one million processing tasks per week, began in 2011 with the launch of theSkyNet, a placing theSkyNet on par with a supercomputer project that harnesses spare computing power with between 60 and 100 TFLOPs of compute during down times to help researchers process power, or just shy of a top 500 supercomputer. astronomical data. The initiative was the first distributed computing project based in Australia. Over the last six years, more than 54,000 people have processed data for theSkyNet and At any given time, day or night, the website has generated more than 830,000 unique visits from 181 countries.
