Cosmic Light


On 20 December 2013, The United Nations (UN) General Assembly 68th Session proclaimed 2015 as the International Year of Light and Light-based Technologies (IYL 2015). (Related press release can be dowloaded on this in this link (zip format, 145 KB))

This International Year has been the initiative of a large consortium of scientific bodies together with UNESCO, and will bring together many different stakeholders including scientific societies and unions, educational institutions, technology platforms, non-profit organizations and private sector partners.

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.

In particular, the IYL2015 Steering Committee invited the IAU to organise activities under the Cosmic Light theme for the IYL2015.

The IAU Executive Committee recognise the importance of the IYL2015 and support it via the Executive Committee Working Group on the IYL2015.
