Small but WISE

Anyone on Earth can look up and see the moon or stars, but it takes a telescope to get a glimpse of planets and the other bright and strange things that share our universe. Astronomers are always finding new ways to observe far-off galaxies and study the mysteries of deep space.Anyone on Earth can look up and see the moon or stars, but it takes a telescope to get a glimpse of planets and the other bright and strange things that share our universe. Astronomers are always finding new ways to observe far-off galaxies and study the mysteries of deep space. That’s why, on December 14, NASA blasted a small but mighty telescope into space. The telescope is called WISE and is about as wide around as a trashcan. Don’t let its small size fool you: WISE has a powerful digital camera, and it will be taking pictures of some the wildest objects in the known universe, including asteroids, faint stars, blazing galaxies and giant clouds of dust where planets and stars are born. “I’m very excited because we’re going to be seeing parts of the universe that we haven’t seen before,” Ned Wright told Science News. Wright is the scientist who directs the WISE project, which costs about $320 million. Since arriving in space, the WISE telescope has been circling the Earth, held by gravity in a polar orbit (this means it crosses close to the north and south poles with each lap). Its camera is pointed outward, away from the Earth, and WISE will snap a picture of a different part of the sky every 11 minutes. After six months it will have taken pictures across the entire sky. The pictures taken by WISE won’t 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 that give off infrared radiation. Radiation is energy that travels as a wave. Visible light, including the familiar spectrum of light that becomes visible in a rainbow, is an example of radiation. When an ordinary digital camera takes a picture of a tree, for example, it receives the waves of visible light that are reflected off the tree. When these waves enter the camera through the lens, they’re processed by the camera, which then puts the image together. Voilà! We see a tree. Waves of infrared radiation are longer than waves of visible light, so ordinary digital cameras don’t see them, and neither do the eyes of human beings. But we can feel some types of infrared radiation, in the form of heat. That’s a key idea to why WISE will be able to see things other telescopes can’t. Not everything in the universe shows up in visible light. Asteroids, for example, are giant rocks that float through space — but they absorb most of the light that reaches them. They don’t reflect light, so they’re 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 take pictures of hundreds of thousands of asteroids. Brown dwarfs are another kind of deep-space object that will show up in WISE’s 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. They’re so dim that they’re almost impossible to see with visible light, but in the infrared spectrum they glow. These are just a few of the wonders that will show up in a gallery of WISE’s greatest photos. During its mission, WISE will take pictures of hundreds of millions of stars, asteroids, galaxies and brown dwarfs. Not bad for a flying trashcan!
