Dedicated to the scientists who explore the frontiers of space and astronomyand the results of their unfamiliar findingseach chapter in Space and Astronomy explores one of the frontiers of this science. The development of technology, such as rocket propulsion or orbiting telescopes, is critical in both fields, so this features prominently throughout this comprehensive volume. Science reports on space and astronomy are also explored.Chapters include:Extrasolar PlanetsWorlds Beyond the Solar SystemColonization in Space and On Other WorldsTraveling Among the StarsGravitational WavesFormation and Evolution of GalaxiesThe Hidden UniverseDark Matter and Dark Energy.
