Presents information on the scientific principle of gravity, how it was discovered, and how knowledge of its effects is applied by astronomers. Includes directions for a simple experiment.

Briefly describes beliefs of astronomers from ancient times to 1609, when Galileo's discoveries through the telescope gave birth to modern astronomy.

Recounts the story of Radcliffe-educated Henrietta Swan Leavitt, who in the face of ill health and progressing hearing loss discovered a new law that enabled astronomers to use variable stars in order to measure the universe.

How Old Is the Universe? tells the incredible story of how astronomers solved one of the most compelling mysteries in science and, along the way, introduces readers to fundamental concepts and cutting-edge advances in modern astronomy. --From publisher description.

This book describes the objects that reside in the Milky Way galaxy, including stars, nebulas, clusters, and black holes, and explains what astronomers have discovered about other galaxies.

"Deep space holds materials left over from the formation of the solar system. Astronomers have been making exciting discoveries on the outermost fringes and the New Horizons spacecraft brings new insights into the origins of the sun and planets"-- The cold, dark world that lies at the farthest reaches of our solar system holds a vast collection of secrets. For the most of human history, we had no idea anything was out there. Utilizing photographs...

Describes how various cultures and astronomers view the moon, as recorded in legend and in fact.

"Taking its name from the moon's dark plains, misidentified as seas by early astronomers, The Black Maria investigates African diasporic histories, the consequences of racism within American culture, and the question of human identity. Central to this project is a desire to recognize the lives of Eritrean refugees who have been made invisible by years of immigration crisis, refugee status, exile, and resulting statelessness. The recipient of a 2015...

An account of the century of experimentation that confirmed Einstein's theory of relativity, bringing to life the science and scientists at the origins of relativity, the development of radio telescopes, the discovery of black holes and quasars, and the still unresolved place of gravity in quantum theory. Albert Einstein did nothing of note on May 29, 1919, yet that is when he became immortal. On that day, astronomer Arthur Eddington and his team...
