NASA's next attempt to map invisible specks in the atmosphere that impact climate change and air quality started from a window seat over the Pacific.

Vanderlei Martins, a professor at the University of Maryland Baltimore County, was flying across the Pacific Ocean a few years ago when he looked out the window and decided to photograph the bright white clouds floating by. On a whim, he took out a polarizer, similar to a sunglasses lens, and rotated it in front of his camera as he snapped photos. The result? "I saw rainbows in the clouds," Martins said.
