By carefully measuring different wavelengths of light reflected from the Earth, many of which are invisible to the human eye, satellites reveal a whole new level of information about our planet. At these specially designed “Pepper’s Ghost illusion” boxes, visitors turn a knob to fade between true-color and false-color satellite images. Through the activity, visitors learn how a satellite’s sensors are able to measure sea surface temperature in the Atlantic Ocean and track atmospheric pollution over Central America.
