Tara, an Indian-American junior at Brierly prep school, feels her world dramatically change when a mirror planet to Earth is discovered and she, in this new era of scientific history, reconsiders her self and possible selves.

For anyone who has ever looked up at the stars and wondered what it all means, Isaac Asimov's Guide to Earth and Space is indispensable. In this audio, Asimov's gift for popular and entertaining exposition has never been better deployed, with his succinct answers to the most intriguing questions about planets, stars, and galaxies. What are quasars? How was the Earth formed? Puzzled by pulsars? Perplexed by the Big Bang? Bewildered by black holes?...

Discusses why scientists believe in the existence of black holes, what they are, how they are formed, and how they are detected.

Presents a pictorial bilingual dictionary of over 22,000 words in Spanish and English organized by subjects and disciplines such as astronomy, science, sports, games, architecture, and clothing.

"Benjamin Banneker is known and admired for his work in science, mathematics, and astronomy. He was born free at a time in America, 1731, when most African Americans were slaves. At the age of 22 he built a strike clock based on his own drawings and using a pocket-knife" --

There is more to the universe than meets the eye--a lot more. In recent years, scientists have discovered that 95 percent of the contents of the cosmos are invisible to our current methods of direct detection. Yet something is holding galaxies and galaxy clusters together, and something else is causing space to fly apart. Scientists call these invisible components dark matter and dark energy: "dark" because these phenomena do not emit light. Dark...

"Physics is the study of the natural world, an experimental science that lies at the heart of all other sciences. It is an effort to make sense of the world at a fundamental level, to unify and describe observable physical phenomena. 'Classical' refers to the pre-20th century developments in physics, a reductionistic, 'realist' approach that continues to be one of the most productive and powerful tools in understanding nature. We begin with a broad...

"In 1916, Einstein became the first to predict the existence of gravitational waves: sounds without a material medium generated by the unfathomably energy-producing collision of black holes. Now, Janna Levin, herself an astrophysicist, recounts the story of the search, over the last fifty years, for these elusive waves--a quest that has culminated in the creation of the most expensive project ever funded by the National Science Foundation ($1 billion-plus)....
