Chandra Sketches: Our Connection With Light

View/Listen
Narrator (April Hobart, CXC): We rely on light - both natural and artificial - to brighten and power our world, but also for so much more.

We use light-based medical tools to help understand and defeat disease.

We use light to advance manufacturing, which helps drive the global economy and move us toward sustainable practices.

We use light to monitor our climate and forecast the weather.

We use light from the cosmos to understand distant galaxies, to look for signs of life out there, and to learn more about our own planet.

Whether it comes from the Sun, a distant galaxy or a neon sign around the corner, light is all around us. We use it to communicate, navigate, learn and explore.
