All objects emit infrared radiation -- the hotter an object is, the more intensely it radiates infrared wavelengths. Human eyes cannot see these wavelengths, but with the help of false-color imaging, temperature differences become visible and invisible features are suddenly illuminated. In this interactive gallery produced for Teachers' Domain, see what hydrothermal features and other objects look like in both visible and infrared light.
