"Stellar Physics" is a an outstanding book in the growing body of literature on star formation and evolution. Not only does the author, a leading expert in the field, very thoroughly present the current state of knowledge on stellar physics, but he handles with equal care the many problems that this field of research still faces. A bibliography with well over 1000 entries makes this book an unparalleled reference source."Stellar Evolution and Stability" is the second of two volumes ...

NEW YORK TIMES BESTSELLER • Thirteen extraordinary essays shed new light on the mystery of the universe—and on one of the most brilliant thinkers of our time.“[Hawking] sprinkles his explanations with a wry sense of humor and a keen awareness that the sciences today delve not only into the far reaches of the cosmos, but into the inner philosophical world as well.”—The New York Times Book ReviewIn his phenomenal bestseller ...

Cutting-edge astrophysics that builds on Einstein's theories to find the unseen matter that fills the Universe.Dark energy. Dark matter. These strange and invisible substances don't just sound mysterious: their unexpected appearance in the cosmic census is upending long-held notions about the nature of the Universe. Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that...

An Introduction to Astronomy by F.R. Moulton - The definitive text for learning about the amazing science of Astronomy. The progress of mankind has been marked by a number of great intellectual movements. At one time the ideas of men were expanding with the knowledge which they were obtaining from the voyages of Columbus, Magellan, and the long list of hardy explorers who first visited the remote parts of the earth. At another, millions of men laid down their lives in order that ...

It's lucky you're here. But for a series of choices, accidents and coincidences - any of which could have gone otherwise - your life would have been very different.The same goes for reality. We live in just one of many possible worlds - but we can imagine parallel universes in which dinosaurs still rule the Earth, the Russians got to the moon first, everyone's a vegetarian or time itself flows backwards. And that's just for starters.What if the laws of physics were di...

When a leaf falls on a windy day, it drifts and tumbles, tossed every which way on the breeze. This is chaos in action. In Fly Me to the Moon, Edward Belbruno shows how to harness the same principle for low-fuel space travel--or, as he puts it, "surfing the gravitational field."Belbruno devised one of the most exciting concepts now being used in space flight, that of swinging through the cosmos on the subtle fluctuations of the planets' gravitational pulls. His idea was me...

Titan is practically a planet in its own right, with a diameter similar to that of Mercury, methane rainstorms, organic soot and ethane seas. All of the most detailed knowledge on the moon's geology, volcanology, meteorology, marine sciences and chemistry are gathered together here to paint a factually accurate hypothetical future of early human colonization on this strange world.The views from Titan’s Mayda Outpost are spectacular, but all is not well at the moon's remote science ...

The field of astrometry, the precise measurement of the positions, distances and motions of astronomical objects, has been revolutionized in recent years. As we enter the high-precision era, it will play an increasingly important role in all areas of astronomy, astrophysics and cosmology. This edited text starts by looking at the opportunities and challenges facing astrometry in the twenty-first century, from space and ground. The new formalisms of relativity required to take advantage of ...

This is one of a planned series called Calculations for Science Fiction Writers. Other chapters will include space travel with constant acceleration, relativistic and nonrelativistic cases, elliptical orbits, rotational dynamics, and more. For those writers who want to get the details right!Circular orbits are the simplest kind, and some quick and easy calculations will make your science fiction stories involving planets and satellites a lot more credible. The circular orbit is a s...

Oceans were long thought to exist in all corners of the Solar System, from carbonated seas percolating beneath the clouds of Venus to features on the Moon's surface given names such as "the Bay of Rainbows” and the "Ocean of Storms." With the advent of modern telescopes and spacecraft exploration these ancient concepts of planetary seas have, for the most part, evaporated. But they have been replaced by the reality of something even more exotic. For example, although it is still uncertain ...

The stars are very far away in terms of distances, but Not in terms of the times required to travel the distances. By applying Einstein's proven principle of Time Contraction, the many Earth type worlds orbiting distant stars become readily available for colonization. They are waiting to be claimed, it is only necessary to go there.This book explains why star travel is possible Now, and how it can be accomplished N...
