Help Measure the Night Sky.
Become a citizen scientist and support University of Melbourne students
How dark is the night where you live?
We’re inviting everyone to take part in a Globe at Night observation and help build a better picture of light pollution.
Globe at Night is an international citizen science program that asks people to step outside after dark, observe the stars, and record what they can see. Your observation contributes to a global dataset used to understand how artificial light is changing the night sky.
This campaign also supports students from the University of Melbourne, who are using community observations to explore light pollution and how it varies across different places.

How to take part
It’s simple:
- Go outside after dark.
- Find the nominated constellation for the campaign.
- Compare what you can see with the Globe at Night star charts.
- Submit your observation online.
You don’t need a telescope or any specialist equipment. Just your eyes, a few minutes, and a clear view of the sky.
Why your observation matters
Every observation helps us understand where skies are getting brighter and where darkness is being preserved. By taking part, you are helping researchers and students:
- measure light pollution
- compare sky brightness between locations
- understand changes over time
- build awareness of the value of dark skies
- support better lighting choices in our communities
Join us on 3 & 10 October 2026
Whether you live in the city, suburbs, coast or country, your observation is useful.
Take a few minutes to step outside, look up and become a citizen scientist.
