Galaxy Explorer is an online citizen science project

 Photography by Paul Bourke and Jonathan Knispel. Supported by WASP (UWA), iVEC, ICRAR, and CSIRO.


Anyone can join in and help astronomers classify galaxies up to 3-4 billion light years away.

You can do it ALL from the comfort of your lounge room.  All you need is a computer or tablet and a connection to the internet.

Classifying these images will help Australian astronomers with their research into how galaxies grow and evolve.

Citizen science

Galaxy Explorer is an online citizen science project undertaken by ABC Science in conjunction with the International Centre for Radio Astronomy Research, WA.

We’re taking a crowd-sourcing approach to reduce this workload and ask regular folk to get involved and help the scientists with their research work.

This crowd-sourcing approach is called ‘citizen science’ – it’s about using the power of the people to increase the breadth of science by gathering or processing information important to a scientific project.

How it works? Get started

All you need to do before you start classifying galaxies is a quick tutorial on what to do.  You can return to this tutorial later if you need to refresh your knowledge or have any questions. The tutorial will give you a basic understanding on what you need to do.

Register (or not!)

You don’t need to register to take part in Galaxy Explorer but there are definite advantages to doing so….

+ You can keep a gallery of the most gorgeous galaxies you see, to share, show-off or just look at whenever you want. 

+ You’ll be able to keep track of the number of galaxies you do.

+ You can return anytime to do more galaxy classifying –  helping the scientists out even more. You only need to provide a few details to register. 

+ Schools can also join in – an adult just needs to register for the group.

The competition

Please note, the competition to win a wi-fi telescope; or an iPad for your school has now closed.

Keep going!

You can come back anytime to transcribe more observations and we’d love it if you do!
