When observing the sky on a very clear, dark night, the soft glow of the Milky Way with its thousands of stars can be seen with the naked eye. Over the centuries since Galileo Galilei first pointed a telescope at the galaxy in 1609, this awe-inspiring yet easily visible panorama was our cosmos, our celestial world. With each new scientific discovery, however, this cosmos has grown dramatically, increasing rapidly over the last several decades. As we look deeper into space, the earlier phases of the cosmos are unveiled to us, but we know that even with the largest telescopes, we will see...

Observers no longer need to wonder what they will turn their attention to each night of the year with this updated text of a beloved favorite from Sir Partick Moore. His night-by-night account of the stars is the best possible guide an observer could ask for, and now includes the latest data for the years 2015-2020, preserving and extending Sir Patrick Moore's legacy.

This new edition of his classic text makes it easy to see why Sir Patrick Moore was such a helpful guide to generations of budding astronomers, professional and amateur alike. For every night of the year Patrick gives...

In the first chapters the author describes how our knowledge of the position of Earth in space and time has developed, thanks to the work of many generations of astronomers and physicists. He discusses how our position in the Galaxy was discovered, and how in 1929, Hubble uncovered the fact that the Universe is expanding, leading to the picture of the Big Bang. He then explains how astronomers have found that the laws of physics that were discovered here on Earth and in the Solar System (the laws of mechanics, gravity, atomic physics, electromagnetism, etc.) are valid throughout the...

The Authorized Albert Einstein Archived Edition: E=mc2 may be Einstein s most well-known contribution to modern science. Now, on the one-hundredth anniversary of the theory of general relativity, discover the thought process and physics behind this famous equation.

In this collection of his seven most important essays on physics, Einstein guides his reader step-by-step through the many layers of scientific theory that formed a starting point for his discoveries. By both supporting and refuting the theories and scientific efforts of his predecessors, Einstein reveals in a...

Dr. Orchiston is a foremost authority on the subject of New Zealand astronomy, and here are the collected papers of his fruitful studies in this area, including both those published many years ago and new material. The papers herein review traditional Maori astronomy, examine the appearance of nautical astronomy practiced by Cook and his astronomers on their various stopovers in New Zealand during their three voyagers to the South Seas, and also explore notable nineteenth century New Zealand observatories historically, from significant telescopes now located in New Zealand to local and...

This extensive thesis work covers several topics, including intensity and polarization, focusing on a new polarization bias reduction method. Vidal studied data from the WMAP satellite, which is low signal-to-noise and as such has to be corrected for polarization bias. He presents a new method for correcting the data, based on knowledge of the underlying angle of polarization. Using this novel method, he sets upper limits for the polarization fraction of regions known to emit significant amounts of spinning dust emissions. He also studies the large-scale loops and filaments that dominate...

This book gives an accessible account of the history of the Universe; not only what happened, but why it happened. An author of textbooks on the early Universe and inflation, David Lyth now explains both cosmology and the underlying physics to the general reader. The book includes a detailed account of the almost imperceptible structure in the early Universe, and its probable origin as a quantum fluctuation during an early epoch known as the epoch of inflation. It also explains how that early structure is visible now in the cosmic microwave radiation which is our main source of information...
