1、t 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.Thats a key idea to why WISE will be able to see things other telescopes cant. Not everything in the universe shows up in visible light. Asteroids, for

2、example, are giant rocks that float through space but they absorb most of the light that reaches them. They dont reflect light, so theyre difficult to see. But they do give off infrared radiation, so an infrared telescope like WISE will be able to produce images of them. During its mission WISE will

3、 take pictures of hundreds of thousands of asteroids.Brown dwarfs8 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 start9 the same kind of reactions that power stars such as the sun. Instead,

4、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.教材的原题：1. What is so special about WISE?A It is small in size but carries a large camera.B It is as small as a trashcan.C Its digital camera can help

12、scovered by University of Michigan1researchers could lead to solar power without traditional semiconductor-based solar cells.The researchers found a way to make an “optical 1 , ” said Stephen Rand, a professor in the departments of Electrical Engineering and Computer Science, Physics and Applied Phy

13、sics.Light has electric and magnetic components. Until now, scientists thought the 2 of the maghetic field were so weak that they could be ignored. What Rand and his colleagues found is that at the right intensity, when light is traveling through a material that does not conduct electricity, the lig

14、ht field can generate magnetic effects that are 100 million times stronger than3 expected. 4 these circumstances, the magnetic effects develop strength equivalent to a strong electric effect.“This could lead to a new kind of solar cell without semiconductors and without absorption to produce charge

15、separation, ” Rand said. “In solar cells, the 5 goes into a material, gets absorbed and creates heat. Here, we expect to have a very low heat load2. Instead of the light being absorbed, energy is stored in the magnetic moment3. Intense magnetization can be induced by intense light and then it is ult

16、imately capable of providing a capacitive power 6 ”What makes this possible is a previously undetected brand of “optical rectification4, ” says William Fisher, a doctoral student5 in applied physics. In traditional optical rectification, lights electric field causes a charge separation, or a pulling

17、 7 of the positive and negative charges6 in a material. This sets up a voltage, similar to 8 in a battery.Rand and Fisher found that under the right circumstances and in right types of materials, the lights magnetic field can also create optical rectification. The light must be shone through7 a9 tha

18、t does not 10 electricity, such as glass. And it must be focused to an intensity of 10 million watts per square centimeter8. Sunlight isnt this intense on its own, but new materials are being sought that would work at lower intensities, Fisher said.“In our most recent paper, we show that incoherent

19、light9 like sunlight is theoretically almost as 11 in producing charge separation as laser light is, ” Fisher said.This new 12 could make solar power cheaper, the researchers say. They predict that with improved materials they could achieve 10 percent efficiency in 13 solar power to useable energy.

20、Thats equivalent to todays commercial-grade solar cells.“To manufacture 14 solar cells, you have to do extensive semiconductor processing, ” Fisher said. “All we would need are lenses to focus the light and a fiber to guide it. Glass works for 15 Its already made in bulk10, and it doesnt require as
