Discover how astrophysicists map the universe. Focus on the tricky problem of calculating distances, seeing how a collection of overlapping techniques provide a "cosmic distance ladder" that works from nearby planets (by means of radar) to stars and galaxies (using parallax and Cepheid variable stars) to far distant galaxies (by observing a type of supernova with a standard intrinsic brightness).

Dr. Carroll explains the subject of dark matter and dark energy in 24 lectures. He explains why scientists believe we live in a smooth, expanding universe that originated in a hot, dense state called the Big Bang. He describes the features of the infant universe that led to the large-scale structure we observe today. He takes you through the standard model of particle physics and shows how it provides the framework for understanding the interaction...

Violet and her family venture to a local park to partake in some late-night stargazing. Telescope and space book in tow, Violet is ready to explore and discover the night sky for herself, wherever that may lead.

When a rainstorm prevents Nancy and her best friend, Robert, from getting to the planetarium the night of a class field trip, she has a brilliant idea for making things better.

Publisher Annotation: Planet Earth is in the Milky Way Galaxy, the cloudy band of light that stretches clear across the night sky. How many galaxies are there in the universe? For years astronomers thought that the Milky Way was the universe. Now we know that there are billions of them. Gail Gibbons takes the reader on a journey light-years away.

A thrilling nonfiction tour of the cosmos that brings the universe down to Earth, from one of the all-time masters of science fiction.
 
No one makes sense out of science like Isaac Asimov. Are you puzzled by pulsars? Baffled by black holes? Bewildered by the big bang? If so, here are succinct, crystal-clear answers to more than one hundred of the most significant questions about the essential nature of the universe—questions...

From asteroids to black holes, this easy-to-understand guide takes you on a grand tour of the universe, and provides an easy-to-follow introduction to the night sky.

Jack and Annie present information about the universe, including our solar system, and briefly describe the history of space travel and of the science of astronomy.

"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)....
