GDC Awarded a Regional Economic Grant

We have some very, very exciting news!

The Gravity Discovery Centre has been awarded a $190,000 Regional Economic Grant to develop Indigenous style accomodation, called Mia Mias, on site at the GDC! The grant was announced by Alannah MacTiernan, Minister for Regional Development, Agriculture and Food.

There are seven Mia Mias planned and they will be laid out in the pattern of the Yogolarang (also known as the Pleiades or seven sisters). The accomodation has been designed in collaboration with Indigenous Elder, Dr Noel Nannup and will be able to house guests and school groups who visit the centre.

We’re very excited about this venture and can’t wait to embark on this journey.

International Dark Sky Week!

This year, March the 31st until April the 7th will be International Dark Sky Week! International Dark Sky Week aims to spread awareness about the damaging global effects of light pollution.

What is International Dark Sky Week and Why Does it Matter?

International Dark Sky Week is celebrated annually and was established in 2003 by high school student, Jennifer Barlow. The program aims to spread awareness about the importance of preserving dark skies, issues involved with light pollution around the globe, and to educate people on how to minimise it’s harmfulness.

“I want people to be able to see the wonder of the night sky without the effects of light pollution. The universe is our view into our past and our vision into the future. … I want to help preserve its wonder.” – Jennifer Barlow

What is Light Pollution?

Light pollution is the brightening of the night sky by excessive use of artificial lights, such as street lights, building lights and other man made technologies. The amount of outdoor light currently used is problematic because it’s overly bright, inadequately shielded and there’s often much more light than is actually required!

There are a number of negative effects that light pollution is having, aside from the fact that we no longer get to see the beauty of the night sky. Research has revealed that light pollution is also having a negative impact on the health of humans and on wildlife. Some of these negative impacts include problems with breeding, sleep cycles and there are even strong links to an increased risk of breast and prostate cancer.

The Gingin Dark Sky Reserve

IDA Energy Waste
The Gravity Discovery Centre & Observatory has spectacular dark skies.


The Gravity Discovery Centre & Observatory is working together with the City of Wanneroo; Main Roads WA; the Shire of Gingin; and the Department of Planning, Lands and Heritage to create a dark sky reserve at the Gravity Discovery Precinct (70km north of the Perth CBD). The dark sky reserve will include 2000KM squared of protected night sky within the Shire of Gingin. The central core is reserved for astronomy tourism, astronomy education, Aboriginal cultural heritage and astronomical scientific endeavour; while the rest of the reserve will serve as a buffer for the prevention of localised light pollution.

We hope to protect our local wildlife; the many scientific endeavours undertaken in our precinct; and to ensure that future generations will get to experience the wonders of the night sky.


How Can You Help?

Unlike many other threats facing our planet, light pollution can be reversed! According to the International Dark Sky Association, here are some things that you can do to help!


  • Minimise the light you use around your home. Shield your outdoor lighting or angle it downwards and only use light when you need it for the task at hand.

  • Host a star party or attend one! Lots of astronomy clubs are holding public events for International Dark Sky Week (our astronomers at the Gravity Discovery Centre will be talking about Dark Sky Week at our regularly scheduled observatory nights!).

  • Help to educate your friends, family and community about the effects of light pollution. Help them think of ways they can reduce light usage in their homes!

  • You can become a ‘Citizen Scientist with GLOBE at Night or the Dark Sky Rangers. Through this you can contribute to a global database of light pollution measurements by documenting the light pollution in your area and sharing the results!

  • Watch IDA’s video, “Losing the Dark” (for free) and follow them on Facebook and Twitter.

    UWA Awarded $890,000 to teach Einstein’s physics in schools


    Researchers at The University of Western Australia have been awarded $890,000 in Federal Government funding for a ground-breaking international research project to teach modern physics through primary and secondary school.

    Federal Minister for Education Dan Tehan today announced more than $xx million in funding for university research projects through the Australian Research Council (ARC).

    UWA’s project will be led by internationally recognised physicist Emeritus Professor David Blair who played a key role in the discovery of gravitational waves. Professor Blair is outreach program leader at the Centre of Excellence for Gravitational Wave Discovery (OzGrav-UWA).

    Professor Blair said it was hoped the project would mobilise a huge team of physicists and educators at UWA, Curtin University, ANU, five international universities, along with the WA Department of Education, the Science Teachers Association, the Association of Independent Schools, Mt Lawley Senior High School and the Gravity Discovery Centre.

    “We’ve already proved that kids love Einstein’s physics and are keen to learn it. Now we can work on creating a full school curriculum that teaches children about the nature of space, time and gravity right from year three all the way through their schooling,” he said.

    Following a previous project that showed that it was possible and beneficial to teach the modern Einsteinian paradigm of space, time, matter, light and gravity to students as young as eight years old, this project aims to test and evaluate a seamless progression of learning modern physics through primary and secondary school.

    It will sequence, integrate and test research-informed teaching and learning materials, and assessment instruments developed through a seven-nation collaboration involving the US, Norway, Germany, Scotland, South Korea and China.

    Research across 24 schools will be reviewed by a panel comprising members of professional organisations and curriculum authorities, and learning resources will be widely disseminated, with view to worldwide introduction of Einsteinian science at school.

    Partner organisations are providing $560,000 cash and $4.38 million in-kind and include WA’s Gravity Discovery Centre Foundation, Department of Education, Association of Independent Schools of WA, Science Teachers Association of WA, Mount Lawley Senior High School, ANU, University of Oslo, Seoul National University, University of Hildesheim in Germany, University of Glasgow and Beijing Normal University.
