Fascinating, engaging, and extremely visual, FOUNDATIONS OF ASTRONOMY, Enhanced Thirteenth Edition, is renowned for its current coverage, reader-friendly presentation, and detailed, yet clear explanations. The authors' goals are to help you use astronomy to understand science-and use science to answer two fundamental questions: What are we? And how do we know?

Introduction to Cosmology provides a rare combination of a solid foundation of the core physical concepts of cosmology and the most recent astronomical observations. The text is designed for advanced undergraduates or beginning graduate students and assumes no prior knowledge of general relativity. An emphasis is placed on developing the students' physical insight rather than losing them with complex math. An approachable writing style and wealth of fresh and imaginative analogies from "everyday" physics are used to make the concepts of cosmology more accessible.

Many national flags display astronomical features - Sun, Moon, stars - but are they really based on existing astronomical objects? The United States flag sports 50 stars, one for each state, however none of them are linked to real stars. Further, the lunar crescent is often shaped like the Sun being eclipsed by the Moon. At times, stars are seen right next to the crescent, where the darkened disc of the moon should be! This book will present true astronomical objects and patterns highlighted on national flags and link informative capsules about these objects to the political reasons why they were chosen to adorn such an important symbol.

When America's first astronauts launched into outer space, Tony Jenzano helped them learn to navigate by the stars. As the leader of a big planetarium in a small town, Tony was the man who made the stars shine. Without Tony, NASA's first space travelers would have been lost in space.

Offers a unique combination of informative text, magnificent illustrations and stylish design Examines the 100 most important discoveries since the invention of the telescope Features spectacular photographs, taken with the largest telescopes on Earth and in space, that portray distant corners of the universe Author Govert Schilling is a renowned astronomy journalist and science communicator

In his "Atlas of Astronomical Discoveries," astronomy journalist Govert Schilling tells the story of 400 years of telescopic astronomy. He looks at the 100 most important discoveries since the invention of the telescope. Doing what Schilling does best, he takes the reader on an adventure through both space and time. Photographs and amazing pictures line the pages of this book, offering the reader an escape from this world and an invitation to a world far beyond what the unaided human eye can detect.

Like no other telescope ever invented, the NASA/ESA Hubble Space Telescope has given us magnificent high resolution views of the gigantic cosmic collisions between galaxies. Hubble's images are snapshots in time and catch the colliding galaxies in different stages of collision. Thanks to a new and amazing set of 60 Hubble images, for the first time these different stages can be put together to form a still-frame movielike montage showing the incredible processes taking place as galaxies collide and merge.

The significance of these cosmic encounters reaches far beyond aesthetics. Galaxy mergers may, in fact, be some of the most important processes that shape our universe. Colliding galaxies very likely, hold some of the most important clues to our cosmic past and to our destiny. It now seems clear that the Milky Way is continuously undergoing merging events, some small scale, others on a gigantic scale. And the importance of this process in the lives of galaxies is much greater than what was previously thought.

Die skrywer se doelstelling met hierdie publikasie is om die beginsels van sterrekunde toeganklik te maak vir almal, om ’n teks daar te stel wat bruikbare toeligting vir die amateursterrekundige is en kan dien as voorbereiding vir verdere studie in die sterrekunde. Van Zyl se eenvoudige, onderhoudende skryfstyl dra verder by tot die boek se toeganklikheid vir sterrekundiges sowel as leke met ’n besondere belangstelling in die heelal. Deurgaans word gepoog om te verduidelik hoe sterrekundiges te werk gaan. Om begrip te vergemaklik, verskyn ook 11 bladsye bylaes waarin die wiskunde wat gebruik word uit grondbeginsels herlei word. Dit bevat gedetailleerde beskrywings en verduidelikings van die heelal se geheime. Inligting oor nuwe ontdekkings en teoriee, kleurvolle diagramme en foto’s verhoog die waarde.

Throughout the ages, comets, enigmatic and beautiful wandering objects that appear for weeks or months, have alternately fascinated and terrified humankind. The result of five years of careful research, Atlas of Great Comets is a generously illustrated reference on thirty of the greatest comets that have been witnessed and documented since the Middle Ages. Special attention is given to the cultural and scientific impact of each appearance, supported by a wealth of images, from woodcuts, engravings, historical paintings and artifacts, to a showcase of the best astronomical photos and images. Following the introduction, giving the broad historical context and a modern scientific interpretation, the Great Comets feature in chronological order. For each, there is a contemporary description of its appearance along with its scientific, cultural and historical significance. Whether you are an armchair astronomer or a seasoned comet-chaser, this spectacular reference deserves a place on your shelf.

An icon of the last fifty years, Stephen Hawking seems to encapsulate genius: not since Albert Einstein has a scientific figure held such a position in popular consciousness. In this enthralling memoir, writer and physicist Leonard Mlodinow tells the story of his friend and their friendship, offering an intimate account of this giant of science. The two met in 2003, when Stephen asked Leonard if he would consider writing a book with him, the follow up to the bestselling A Brief History of Time. As they spent years working on a second book, The Grand Design, they forged a deep connection and Leonard gained a much better understanding of Stephen's daily life and struggles - as well as his compassion and good humour. Together they obsessed over the perfect sentence, debated the physics, and occasionally punted on Cambridge's waterways with champagne and strawberries. In time, Leonard was able to finish Stephen's jokes, chide his sporadic mischief, and learn how the hardships of his illness helped forge that unique perspective on the universe. By weaving together their shared story with a clear-sighted portrayal of Hawking's scientific achievements, Mlodinow creates a beautiful portrait of Stephen Hawking as a brilliant, impish and generous man whose life was not only exceptional but also genuinely inspiring.

SPACE SPARKS THE IMAGINATION in fantastic ways, but nothing quite captures people's attention more than when we actually reach out and touch another world. Whether it's missions to the Moon, transporting rovers to Mars or landing Philae on a comet, the idea that we can not only picture these worlds from afar, but to touch them is wonderfully inspiring, and it is through cutting-edge robotic technology that it is made possible. In Robots in Space expert space journalist Dr Ezzy Pearson delves into the fascinating robotic history of space exploration, from distant times when stars were an unreachable godly mystery, through the intense Space Race following the Second World War to the Mars missions of the twenty-first century. As we find ourselves on the cusp of a new and exciting space age, Pearson explores how and why humanity turns its best minds to travelling to the stars, and exactly how far we could go.

A beautifully presented, practical gift guide to 50 sights in the skies above us complete with a glow-in-the dark front cover. Explained with fascinating, easy-to-understand commentary from astrophysicist and science communicator, Sarah Barker, and illustrated throughout with captivating drawings by Maria Nilsson, each guide helps you locate an incredible sight.

The book is divided into three main sections and whether you use the naked eye, a telescope, or fall into a black hole of online research, you ll discover the limitless wonder of the skies from otherworldly phenomena on Earth like sun dogs, to planets, moons, stars, lunar craters and galaxy clusters.

Naked Eye: Learn how navigators travelled in the past by finding the North Star; say hello to our astronauts and learn how to spot the International Space Station; see a red supergiant star (Betelgeuse); and find out more about solar eclipses.

Further Afield: Find out more about the next closest galaxy, Andromeda; learn about the discovery of Saturn s ears (or rings!); spot an alien storm that s as big as the Earth; and track Little Green Men and ice volcanoes.

Far, Far Away: Learn how baby stars are created by the Pillars of Creation; marvel at the Hubble Deep Field; and unearth the brightest things in our universe, quasars.

The book also includes advice on ideal conditions for observing the stars, telescopes and binoculars, and navigating the skies. With extra tips and a rundown of useful tools, you ll find everything you need to get out there and look up!

Are we alone in the universe, or are there other life forms 'out there'? This is one of the most scientifically and philosophically important questions that humanity can ask. Now, in the early 2020s, we are tantalizingly close to an answer. As this book shows, the answer will almost certainly be that life forms are to be found across the Milky Way and beyond. They will be thinly spread, to be sure. Yet the number of inhabited planets probably runs into the trillions. Some are close enough for us to detect evidence of life by analysing their atmospheres. This evidence may be found within a couple of decades. Its arrival will be momentous. But even before it arrives we can anticipate what life elsewhere will be like by examining the ecology and evolution of life on Earth. This book considers the current state of play in relation to these titanic issues.

Astronomers have successfully observed a great deal of the Universe's history, from recording the afterglow of the Big Bang to imaging thousands of galaxies, and even to visualising an actual black hole. There's a lot for astronomers to be smug about. But when it comes to understanding how the Universe began and grew up we are literally in the dark ages. In effect, we are missing the first one billion years from the timeline of the Universe. This brief but far-reaching period in the Universe's history, known to astrophysicists as the 'Epoch of Reionisation', represents the start of the cosmos as we experience it today. The time when the very first stars burst into life, when darkness gave way to light. After hundreds of millions of years of dark, uneventful expansion, one by the one these stars suddenly came into being. This was the point at which the chaos of the Big Bang first began to yield to the order of galaxies, black holes and stars, kick-starting the pathway to planets, to comets, to moons, and to life itself. Incorporating the very latest research into this branch of astrophysics, this book sheds light on this time of darkness, telling the story of these first stars, hundreds of times the size of the Sun and a million times brighter, lonely giants that lived fast and died young in powerful explosions that seeded the Universe with the heavy elements that we are made of. Emma Chapman tells us how these stars formed, why they were so unusual, and what they can teach us about the Universe today. She also offers a first-hand look at the immense telescopes about to come on line to peer into the past, searching for the echoes and footprints of these stars, to take this period in the Universe's history from the realm of theoretical physics towards the wonder of observational astronomy.

With over 150,000 copies sold since its first publication, this is one of the most popular astronomy books of all time.

Dr Carrie Nugent is an asteroid hunter - one of the select group of scientists working diligently to map our cosmic neighbourhood. For the first time ever we are reaching the point where we may be able to prevent a natural disaster resulting from an asteroid collision. Nugent will delve into the impact asteroids have had in the past: the extinction of the dinosaurs, the earth-sized hole Shoemaker-Levy 9 left in Jupiter just a few years ago, how the surprise hit on Chelyabinsk in Russia could have started a war and unlucky Ms Anne Hodges - the only person (that we know of) in modern history to be the victim of a direct hit. Nugent will also reveal the cutting-edge work that she is part of - using NASA's NEOWISE telescope to track down near-Earth asteroids. NEOWISE has seen over 158,000 asteroids and discovered over 30,000. We will also get a rare glimpse into the work of this band of asteroid hunters and their techniques. Asteroid orbits are chaotic which means a small early change has a big impact later on. The successful hunt and mapping of asteroids could mean nothing less than saving life on Earth.

Sasol First Field Guide to Skywatching in Southern Africa is a fascinating insight into the southern skies by night. Full-colour photo graphs and illustrations, monthly star charts and easy-to-read text will help the budding astronomer to identify the more visible objects in our night skies, as well as those that are less obvious, and discover some of the extraordinary phenomena of our galaxy.

Three leaders in the field of thin-film optics present a detailed and self-contained theoretical study of planar multilayers and how they can be effectively exploited in both traditional and modern applications. Starting with a discussion of the relevant electromagnetic optics, the fundamental optical properties of multilayers are introduced using an electromagnetic approach based on a direct solving of Maxwell's equations by Fourier transforms. This powerful approach is illustrated through the comprehensive description of two of the most important phenomena in multilayers, i.e. giant field enhancement in dielectric stacks and light scattering from thin-film optical filters. The same approach is extended to the description of the operation of planar microcavities and the balance of energy between radiated and trapped light. This book will be valuable to researchers, engineers and graduate students with interests in nanophotonics, optical telecommunications, observational astronomy and gravitational wave detection.
