　　Small But Wise

　　Im very excited because were going to be seeing parts of the universe that we havent seen before, said Ned Wright, a scientist who directs the WISE project.

　　The pictures taken by WISE wont be like everyday digital photographs, however. WISE stands for Wide-field Infrared Survey Explorer. As its name suggests, the WISE camera takes pictures of features that give off infrared radiation.

　　Waves of infrared radiation are longer than waves of visible light, so ordinary digital cameras dont see them, and neither do the eyes of human beings. Although invisible to the eye, longer infrared radiation can be detected as warmth by the skin.

　　Brown dwarfs are another kind of deep-space object that will show up in WISEs pictures. These objects are failed stars-which means they are not massive enough to jump start the same kind of reactions that power stars such as the sun. Instead,brown dwarfs simply shrink and cool down. Theyre so dim that theyre almost impossible to see with visible light, but in the infrared spectrum they glow.
