Internacional Astronomical Union

màxim The International Astronomical Union (IAU) recognize the importance of light for astronomy and supports that technology in the achievement of greater energy efficiency, in particular by limiting energy waste, and in the reduction of light pollution, which is key to the preservation of dark skies. The IAU is therefore a supporter of the IYL2015.

IAU IYL2015 CosmicLight Cornerstone Projects

Cosmic Light Awareness

The main aim of this project is to involve schools around the globe in awareness campaigns in the framework of the International Year of Light.

Cosmic Light Educational Kit

The project will assemble a tool kit, the Cosmic Light Educational Kit, with simple tools to address the proposed thematic of the ephemeris, in particular those related the nature of light, the impact of light in our knowledge of the Universe, its importance for our existence.

Quality Lighting Teaching Kit

Poor quality lighting creates safety issues, affect human circadian rhythms, can disrupts ecosystems, impedes astronomy research, and wastes over USD 110 billion/year of energy worldwide. The project goal is to provide quality lighting education to encourage the best use of light for illumination.

Light: Beyond the Bulb

The project aims to increase awareness of the science of light for primarily non-expert audiences with potentially less existing buy-in for science consumption through the creation of an online repository of high-quality, easy-to-reproduce science images and respective captions that tell an interesting and relevant story about the science of light.

Building on the success of the International Year of Astronomy Cornerstone project, the project propose to manufacture and distribute at least 100,000 Galileoscopes to teachers and students (from primary school through college) across the globe. The Galileoscope is an optically excellent but inexpensive telescope kit suitable for both optics education indoors and celestial observations outdoors.
