ABOVE VIDEO: The International Year of Light 2015 recognizes the importance of raising global awareness of how light-based technologies promote sustainable development and provide solutions to global challenges in energy, education, agriculture, and health.

NASA.gov – The year of 2015 has been declared the International Year of Light (IYL) by the United Nations.

Organizations, institutions, and individuals involved in the science and applications of light will be joining together for this yearlong celebration to help spread the word about the wonders of light.

NASA’s Chandra X-ray Observatory explores the universe in X-rays, a high-energy form of light.

By studying X-ray data and comparing them with observations in other types of light, scientists can develop a better understanding of objects likes stars and galaxies that generate temperatures of millions of degrees and produce X-rays.

To recognize the start of IYL, the Chandra X-ray Center is releasing a set of images that combine data from telescopes tuned to different wavelengths of light.

In this image, an expanding shell of debris called SNR 0519-69.0 is left behind after a massive star exploded in the Large Magellanic Cloud, a satellite galaxy to the Milky Way. Multimillion degree gas is seen in X-rays from Chandra, in blue. The outer edge of the explosion (red) and stars in the field of view are seen in visible light from the Hubble Space Telescope.

From a distant galaxy to the relatively nearby debris field of an exploded star, these images demonstrate the myriad ways that information about the universe is communicated to us through light.
