Jo Dunkley combines her expertise as an astrophysicist with her talents as a writer and teacher to present an elegant introduction to the structure, history, and enduring mysteries of the universe. Among the cutting-edge phenomena discussed are the accelerating expansion of the universe and the possibility that our universe is only one of many.
Provides answers to over three hundred of the most commonly asked questions about astronomy posed to author Sten Odenwold on the "Ask the Astronomer" page of his award-winning Web site "The Astronomy Cafe"; grouped by topic
For going on two decades, Scientific American's "Ask the Experts" column has been answering reader questions on all fields of science. We've taken your questions from the basic to the esoteric and reached out to top scientists, professors and researchers to find out why the sky is blue or whether we really only use 10% of our brains. Now, we've combed through our archives and have compiled some of the most interesting questions (and answers) into a series of eBooks. Organized by subject, each eBook provides short, easily digestible answers to questions on that particular branch of the sciences. The second eBook in our series – Astronomy – looks skyward and explains a variety of universal phenomena and theories. Are you curious about how planets acquire rings or what creates those gorgeous spiral arms around galaxies? Or maybe you want to know why the Big Bang didn't collapse into a black hole. Astrophysicists, professors and scientists tackle questions about stars, planets, asteroids, galaxies and nebulae, the expanding universe as well as the oddities – black holes, wormholes and dark matter. Look inside and find out what we know and what we don't know about these wonders.
This reference book consists of questions submitted by the public and Odenwald's answers, taken from the author's "Ask the Astronomer" internet website at the Astronomy Cafe. This is a compilation of the Top-100 questions answered at The Astronomy Cafe between 1995 and 2013 from an archive of over 3000, which were requested over 10 million times. The topics range from Higgs bosons and the nature of gravity, to extra solar Earth-like planets and global warming. There is also a collection of tables that include a list of the known nearby black holes, the most distant objects we know in the universe, and upcoming asteroids that may hit Earth. The general reader may find this easy to read reference an enjoyable way to learn about these topics.

Perfect for fans of STEM, this inspiring picture book biography tells the extraordinary story of pioneering astronomer Maria Mitchell. Maria longed to travel beyond her island of Nantucket. But how? Her father taught her that if you know how to read the stars, they can tell you where you need to go. They spent hours scanning the sky. Maria learned to use astronomers’ tools to measure and track stars. But what could she do with her skills? Then one day, she heard that a prize was being offered to the first person to find a new comet. Could this be the opportunity she was waiting for? From small island girl to renowned astronomer — Martha Mitchell’s story will leave kids starstruck!
In God and the Astronomers, Dr. Robert Jastrow, world-renowned astrophysicist, describes the astronomical discoveries of recent years and the theological implications of the new insights afforded by science into mankind's place in the cosmos. He explains the chain of events that forced astronomers, despite their initial reluctance ("Irritating," said Einstein; "Repugnant," said the great British astronomer Eddington; "I would like to reject it," said MIT physicist Philip Morrison) to accept the validity of the Big Bang and the fact that the universe began in a moment of creation.
The Big Questions series enables renowned experts to tackle the 20 most fundamental and frequently asked questions of a major branch of science or philosophy. Each 3000-word essay simply and concisely examines a question that has eternally perplexed enquiring minds, providing answers from history's great thinkers. This ambitious project is a unique distillation of humanity's best ideas. In Big Questions: The Universe, Dr Stuart Clark tackles the 20 key questions of astronomy and cosmology: What is the universe? How big is the universe? How old is the universe? What are stars made from? How did the Universe form? Why do the planets stay in orbit? Was Einstein right? What are black holes? How did the Earth form? What were the first celestial objects? What is dark matter? What is dark energy? Are we really made from stardust? Is there life on Mars? Are there other intelligent beings? Can we travel through time and space? Can the laws of physics change? Are there alternative universes? What will be the fate of the universe? Is there cosmological evidence for God?
