Here’s why the sun above central Indiana looks red

INDIANAPOLIS, Ind. — You may have noticed a milky appearance to the sky Monday night, or even noticed the sun appeared red! This was due to smoke that was being brought in from wildfires and forest fires in the West.

The colors that we see in the sky have to do with the way light is scattered through the atmosphere. Smoke particles scatter shorter wavelengths (blue) and leave longer wavelengths (red and orange) behind.
