You could be a world record holder AND help scientists map light pollution and the impacts on the environment, by being part of the worlds largest online sustainability lesson about light pollution.

What do you need to do to be a part of this great challenge?

• Sign up – the earlier you do this the better. There will be weekly prizes and tips for the event to registrants.
• Sign in – 21 June, 1Pm AEST
• Watch some videos, answer all 5 questions, and do a night sky observation.
• Finish all parts of the lesson within 24 hours.

Will you help?

The World Record challenge will commence at 1pm AEST on Sunday 21 JUNE – to the whole world.

You can go online and start the lesson, but you must do you light pollution measurement with GLOBE AT NIGHT after dark.

Or you can go online here and pay $3 and be included in the draw to win prizes, receive helpful tips and (if we break the world record) get a copy of the official certificate.

Currently 2,000 people hold the world record – But if we could get 10,000 that would be amazing. That is the record for the largest number of people to participate in an online lesson at once. You never know. We may break TWO world records at once!

Why is this being undertaken and how will what you do help?

Your information will be collected to help see where the dark and light patches all around the world. The idea is to prove that we can still save the night environment in the southern hemisphere. More than anything else, this is an opportunity show policymakers that people care about the impacts of light.

The southern hemisphere is relatively unknown when it comes to light pollution data. Read any of the scientific papers written on this topic, and the vast majority are based in the north. This is likely because the problem is worse in the northern hemisphere and also because we’ve never done any large scale observations in the south before.

You can do this whether you live in the country or a city as a broad span of measurements are required – even if it is cloudy on the night your observations and participation counts and you can do it without having to leave home!

The Australasian Dark Sky Alliance (ADSA) is an independent non-profit charity formed to: educate the public in relation to protecting our night skies, celebrate our night sky heritage and promote environmentally responsible outdoor lighting.
