The latest information from the results of ongoing searches for planets around other stars is presented and explored in this book. Why can we not see them, even though astronomers are convinced of their existence? How conclusions are drawn about them and their make-up is explained.

Through four decades of space exploration and ever-better telescopes, astronomers have searched in vain, unable to find even a single planet orbiting any of the myriad of sunlike stars strewn through the Milky Way. All of this changed in October 1995, when astronomers announced the first planet discovered orbiting another sunlike star. Worlds Unnumbered captures the excitement and explains the significance of these new worlds, with an up-to-the-last-planet account that gives the general reader a vivid picture of the new planets - planets that have already amazed astronomers for their colossal size and orbits that seem impossibly close to their respective suns. Many of the new planets are more massive than Jupiter, yet orbit their stars at distances far less than the distance of the sun to its closest planet. With theories of planet formation, the immense difficulties of observing extrasolar planets, and the prospects for future discoveries of Earthlike planets, Worlds Unnumbered's fast-paced narrative provides its readers with key insights into the question that has fascinated humanity for millennia: Are we alone in the cosmos? And if not, how far must we look to find our closest neighbor?
