It's the first time it's actually shown the difference.

Instead of trapping heat in, and thereby warming the surface, this kind of has the opposite effect.

These results are really exciting and fun as well. Imagine taking something's temperature from almost three billion miles away without making a house call!

Pluto is a dynamic example of what we might call an anti-greenhouse effect.

We?re breaking new ground, laying the foundation for work that will happen in the future.

We're the first to have the combination of resolution and sensitivity to be able to do this experiment.
