UNESCO International Day of Light


Thursday 16th May 10.00am – 19:30


Hands-on STEM activities for students in grades 7-12 to plan, design and create strategies for city lighting that balance the competing concerns of humans and the environment. Using the problem solving process, students learn about issues raised by human created lighting: Glare, Sky Glow, Light Trespass and Excess Energy Consumption. The activities are based on the Quality Lighting Teaching Kit developed by the National Optical Astronomy Observatory for the International Year of Light, 2015. The activities can be booked by schools any time. Contact Judith on 0429 199 312.

In the above image, the extent of some of the night lights in this image are also a function of composite imaging. These new images were assembled from data acquired over nine days in April 2012 and 13 days in October 2012. This means

fires and other lighting (such as ships) could have been detected on any one day and integrated into the composite picture, despite being temporary phenomena.

Because different areas burned (Australia) at different times when the satellite passed over, the cumulative result in the composite view gives the appearance of a massive blaze. These fires are temporary features, in contrast to cities which are always there.
