In this book, John Moffat shares the history of black holes and presents the latest research into these mysterious celestial objects, including the astounding results from gravitational wave detection and the shadow of the black hole.

Carl Edward Sagan (November 9, 1934-December 20, 1996), born in Brooklyn, NY, was an American astronomer and astrophysicist. His best-known scientific contribution was his research on the possibility of extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by exposure to light. The following is a lecture Sagan gave in 1977 during which he discussed the place, scale and geometry of earth–the third planet from the Sun, formed 4.5 billion years ago–in our solar system.

In 1869, a great mystery was born. As astronomers observed a total solar eclipse, for the first time they saw the faint glow of the solar corona, the sun's outer atmosphere. Measurements of a previously unknown wavelength that made up this solar light sparked hot debate among scientists, but it was another 60 years before they discovered that this wavelength was in fact iron being burned at a staggering three million degrees Celsius. With the sun's surface only 6,000 degrees, this shouldn't be possible.

W czasach Kopernika nic nie wskazywało na to, że do największej naukowej rewolucji dojdzie w Europie. O gwiazdach Chińczycy i Arabowie wiedzieli więcej, ale to my jako pierwsi zrozumieliśmy, jakie jest miejsce Ziemi w kosmosie. Ktoś może powiedzieć, że to przede wszystkim zasługa Keplera, Galileusza, Newtona–ale gdybyśmy zapytali tych panów o zdanie, wskazaliby na dzieło bardzo skromnego, genialnego uczonego, który by pracować w spokoju nad swoim odkryciem, zaszył się na skraju Europy.

We now know that the universe is mostly dark, made up of particles and forces undetectable by our most powerful telescopes. The discovery signaled a Copernican-like revolution in astronomy: not only are we not the center of the universe, neither is the stuff of which we're made. Vera Rubin played a pivotal role in this discovery. By showing that some astronomical objects seem to defy gravity, Rubin helped convince the scientific community of the possibility of dark matter. In Bright Galaxies, Dark Matter, and Beyond, Ashley Jean Yeager tells the story of Rubin's life and work.

The moon contains a wealth of natural resources. So, as the Earth's supplies have begun to dwindle, it is no surprise that the world's superpowers and wealthiest corporations have turned their eyes to the stars. As this new Space Race begins, A.C. Grayling asks: who, if anyone, owns the moon? Or Mars? Or other bodies in near space? And what do those superpowers and corporations owe to Planet Earth and its inhabitants as a whole?

It takes a certain amount of courage to step beyond one's day-to-day experiments and look at the big picture - and the origin of the Moon is a big picture question par excellence. Perhaps it makes sense that William Hartmann, one of the two scientists who unraveled the Moon's biggest mystery, is not only a scientist but also a part-time artist and science fiction writer. It took someone with an artist's eye and a fiction writer's speculative temperament to see the big picture....

The violent birth of the universe was only the first bang of a very bumpy ride. This unfathomably cacophonous beginning has spawned blasts, implosions, cosmic cannibalism, collisions, and countless other fleeting energetic events punctuating the cosmos. Although often brief, these transient phenomena pack a powerful punch. Astronomer and science writer C. Renee James introduces us to her colleagues around the world, who are using pioneering research techniques to explore everything from the very first explosions in the universe to the dark energy that could destroy it all.

When Galileo looked to the sky with his perspicillum, or spyglass, roughly 400 years ago, he could not have fathomed the amount of change his astonishing findings a seemingly flat moon magically transformed into a dynamic, crater-filled orb and a large, black sky suddenly held millions of galaxies would have on civilizations.

Ka-boom! probes extremes of size and speed, depth and density, and reveals the stickiest, sweetest, smelliest and nastiest substances known to science. In an unabashed celebration of the exceptional, David Darling takes an enlightening journey through the universe's weirdest and most wonderful extremes.

Africa may have given rise to the first human beings, and Egypt probably gave rise to the first great civilizations, which continue to fascinate modern societies across the globe nearly 5,000 years later. From the Library and Lighthouse of Alexandria to the Great Pyramid at Giza, the ancient Egyptians produced several wonders of the world, revolutionized architecture and construction, created some of the world’s first systems of mathematics and medicine, and established language and art that spread across the known world.
