You may notice the red lights on buildings. This is a good time to talk about wintertime outdoor illumination at the South Pole!

At the end of the day, we’re all here to support science. There are a number of science projects that can only happen during the winter here, because of the unique environmental characteristics of the South Pole (darkness, elevation, weather, air quality, etc). A few of these are extremely sensitive to broad-spectrum visible light.
