章節(jié)摘錄

插圖：One way to explore the universe is by looking atdistant galaxies through telescopes. Even simpletelescopes can help us see stars that are millions oflight-years away. Finding planets, however, is muchmore difficult. Planets and moons give out no light oftheir own. They do reflect some light from theirnearby star, but this light is swamped1 by the light ofthe star. Stars shine about a billion times brighter thanplanets.Although no one has ever seen a planet outside oursolar system, we do know they exist. To detect planets,scientists have to study the effects planets have on thestars they orbit. The presence of a planet can make astar wobble2 slightly. The wobble is produced by theforce of gravity between the star and the planet as theplanet orbits the star. Using the most powerfultelescopes, scientists can tell when a star is wobbling.Since 1996, many planets have been discoveredusing this method. Unfortunately, only very largeplanets can be detected this way. One recentlydiscovered planet is 11 times the size of Jupiter. Jupiteris the largest planet in our solar system. It is about1,319 times bigger than Earth.Scientists don't think there is much hope of findinglife on very large planets. Life, as we know it, seems tobe best suited to planets that are neither too big nortoo small. Any planets they find by detecting wobblingstars probably won't be hospitable to life.
