| 摘要： | The great radio telescope reaches more than 400 ft into the sky, towering above the grassy fields on which it stands in Green Bank, West Virginia. Its enormous parabolic reflector dish - more than 300 ft across - reaches out even farther, metaphorically, at least, probing the heavens, listening to the noise of the universe: the radio waves that scientists use to study the energy output of stars. The telescope can also help map asteroids, moons, planets, and comets; detect warps in the fabric of space; analyze the chemical building blocks of the solar system; and help study the history and future of galaxies. |
