Jeopardy answer: what penguins get from sitting on the ice.

The researchers used data from two satellites: NASA's Sea-viewing Wide Field-of-view Sensor and the National Oceanic and Atmospheric Administration's Advanced Very High Resolution Radiometer. See images here.

It's enough to make a tree-hugger cry. Imagine using evil technology to non-invasively study some of God's happy creatures.
