Product Description
How learning to "listen" to the universe using radio waves has revolutionized our understanding of everything from gravity to little green men. "Passionate and witty" --Publishers Weekly, starred review In space, no one can hear you scream. But the universe is far from silent. It's been speaking all along, broadcasting its stories and secrets, for those who know how to listen. In The Echoing Universe, Emma Chapman tunes us in to the universe and what it is trying to say, through the science of radio astronomy. Everything is sending out signals: the surface of the Moon, distant stars--maybe even extraterrestrials. With radio waves, we can uncover what visible light cannot show us and peer into realms that are otherwise unreachable. Even the hostile surface of Venus, where high temperatures, lethal acid rain, and crushing pressure rapidly annihilate even the hardiest robotic probes, yields its secrets through radio observations. This exhilarating expedition is just the beginning as new and bigger radio telescopes come into play and propel our curiosity well beyond the edge of our galaxy. Despite the seeming silence of space, The Echoing Universe reveals that the future of astronomy is loud and vibrant. When we turn our radio telescopes to the sky and simply listen, we'll discover far more than what our eyes could ever see.
