Showing results for "John" in Astronomy & Space Science

Beginning with our earliest explorations of the night sky, William Waller takes us on an enthralling journey through the Milky Way and far, far beyond. He combines science and history to show how our understanding of everything from black holes to the structure of the universe has evolved over time, illuminating past discoveries and offering contemporary insights into the cosmic histories of stars, planets and galaxies. Whether object of study or curiosity, the universe – and all it contains – is tantalisingly introduced here.

Eclipses have stunned, frightened, emboldened, and mesmerized people for thousands of years. They were recorded on ancient turtle shells discovered in the Wastes of Yin in China, on clay tablets from Mesopotamia and on the Mayan "Dresden Codex". They are mentioned in Homer's Iliad and Odyssey and at least eight times in the Bible. Columbus used them to trick people, while Renaissance painter Taddeo Gaddi was blinded by one. Sorcery was banished within the Catholic Church after astrologers used an eclipse to predict a pope's death.

When Ed White, clad in his gleaming space suit with a large American flag on his left shoulder, eased himself outside his Gemini spacecraft in 1965, Americans had a new space hero. They also learned a new acronym: EVA, short for extravehicular activity, more commonly known as "spacewalking." Though few understood the tremendous risks White was taking in his twenty-two-minute space walk, Americans watched with immense pride and patriotism as White, tethered to Gemini 4, propelled himself around the spacecraft with a pressurized oxygen-fueled zip gun.

Earth, from space, looks like a shimmering gem suspended in an inky, infinite expanse. But this serene image masks the magnificent and volatile interior forces that make life possible for millions of species on the surface. The placid appearances of our neighboring planets similarly belie their powers—and science fiction-worthy features, like diamond rain.

A little over a century ago, a young Albert Einstein presented his general theory of relativity to the world and utterly transformed our understanding of the universe. His theory changed the way we think about space and time, revealed how our universe has been expanding from a hot, dense state called the big bang and predicted black holes. Where the Universe Came From is a 13.8 billiion-year journey through the cosmos.
