After Sir William Herschel's discovery of infrared ,which showed that the Sun emits infrared light, astronomers tried to see if other objects in the universe gave out infrared waves. In 1856, astronomers used thermocouples (devices which convert heat into electric current) to detect infrared radiation from the Moon.
