International Year of Light Blogs

Written by Andrew Clark, IGES

On December 20, 2013 the United Nations General Assembly adopted a resolution proclaiming that 2015 would be the International Year of Light and Light-based Technologies, recognizing the importance of light and light-based technologies in the lives of the citizens of the world. The proclamation stressed that an enhanced global awareness of and increased education in the science and technologies of light are vital for addressing challenges such as sustainable development, energy and community health, as well as for improving the quality of life in both developed and developing countries.

From fueling the photosynthesis of plants to illuminating the written word, light touches every part of our lives here on Earth. And at NASA, it’s not only about visible light but the entire electromagnetic spectrum that helps us explore and understand the universe. From high-energy X-rays to the faintest infrared waves from the early universe, light in all its many forms communicates information like nothing else can.

Light also plays a critical role in new electronics, from faster data transfer speeds through fiber optics, to cheaper and more efficient light sources. NASA has had a hand in developing photonics all along.

Throughout 2015, NASA scientists and educators have been writing blog posts about what light means to them and their research. At NASA Wavelength we would like to highlight these blog posts and associated lists of educational resources to bring this international celebration of light into your classrooms and out-of-school programs.
