Astronomy technology once used to measure the temperature of distant stars and planets now measures the temperature of humans with a high-speed medical thermometer. The hand-held device — based on NASA-developed infrared technology — measures energy emitted from the eardrum to record temperature without contacting any mucous membranes. Since it virtually eliminates cross infection, the tool is especially helpful in caring for newborns and the critically ill.
Even though distant stars and their planets are inconceivably far away from us, NASA scientists have devised many ways to detect them and uncover their secrets. For decades scientists have used infrared readings — or measurements of heat radiated — to better understand stars and planets. More recent advances include the careful study of the "fingerprints" created when light passes through a distant planet's atmosphere, which can tell us about its chemical composition.
