From astronomy and military tactics to television remotes, the unseen radiation of the rainbow "color" beyond red has changed our world.

On February 14 this year, after a four-year-long journey from Earth, NASA's NEAR (Near Earth Asteroid Rendezvous) spacecraft entered into orbit around the asteroid 433 Eros. From its orbit, NEAR conducted the first detailed exploration of an asteroid, remotely acquiring volumes of data about its geology and even the mineralogical composition of its surface rocks--a feat that would have been impossible less than a decade ago. Among the ...
