The obvious answer to the question “why is it dark at night?” is that the sun is shining on the other side of the Earth, and the light of the distant stars is much weaker than the sun.

Is it dark only to eyes like ours that are sensitive to visible light, or is it also dark to infrared, ultraviolet, x-ray and radio ‘eyes’? Join us as Dr. Tom Geballe of Gemini Observatory answers these questions, as well as delving into historical and scientific attempts to understand this simple yet important observation.
