Observing the Universe introduces a range of techniques and skills that will be useful for those wishing to undertake observational work in astronomy and planetary science. Observations have played, and continue to play, a crucial role in developing our understanding of the Universe, and the best way to get a feel for the role of observations is to do some. This comprehensive guide provides a sound basis for tackling astronomy and planetary science observations. It concentrates on generic aspects of observations, including the principles of telescopes and detectors, photometry and spectroscopy, microscopy techniques for analysing samples, teamwork skills, planning for a session at an observatory, keeping records of what you do, estimating uncertainties in measurements, analysing data numerically and graphically, and producing a written report. Including self-assessment questions with full solutions, this self-contained guide is suitable for undergraduate students of astronomy and planetary science, and serious amateur astronomers.

The cutting-edge science that is taking the measure of the universe The Little Book of Cosmology provides a breathtaking look at our universe on the grandest scales imaginable. Written by one of the world's leading experimental cosmologists, this short but deeply insightful book describes what scientists are revealing through precise measurements of the faint thermal afterglow of the Big Bang—known as the cosmic microwave background, or CMB—and how their findings are transforming our view of the cosmos. Blending the latest findings in cosmology with essential concepts from physics, Lyman Page first helps readers to grasp the sheer enormity of the universe, explaining how to understand the history of its formation and evolution in space and time. Then he sheds light on how spatial variations in the CMB formed, how they reveal the age, size, and geometry of the universe, and how they offer a blueprint for the formation of cosmic structure. Not only does Page explain current observations and measurements, he describes how they can be woven together into a unified picture to form the Standard Model of Cosmology. Yet much remains unknown, and this incisive book also describes the search for ever deeper knowledge at the field's frontiers—from quests to understand the nature of neutrinos and dark energy to investigations into the physics of the very early universe.

Witty and thought provoking, two Vatican astronomers shed provocative light on some of the strange places where religion and science meet. “Imagine if a Martian showed up, all big ears and big nose like a child’s drawing, and he asked to be baptized. How would you react?” —Pope Francis, May, 2014 Pope Francis posed that question—without insisting on an answer!—to provoke deeper reflection about inclusiveness and diversity in the Church. But it's not the first time that question has been asked. Brother Guy Consolmagno and Father Paul Mueller hear questions like that all the time. They’re scientists at the Vatican Observatory, the official astronomical research institute of the Catholic Church. In Would You Baptize an Extraterrestrial? they explore a variety of questions at the crossroads of faith and reason: How do you reconcile the The Big Bang with Genesis? Was the Star of Bethlehem just a pious religious story or an actual description of astronomical events? What really went down between Galileo and the Catholic Church—and why do the effects of that confrontation still reverberate to this day? Will the Universe come to an end? And… could you really baptize an extraterrestrial? With disarming humor, Brother Guy and Father Paul explore these questions and more over the course of six days of dialogue. Would You Baptize an Extraterrestrial will make you laugh, make you think, and make you reflect more deeply on science, faith, and the nature of the universe.

In preparing the report, Astronomy and Astrophysics in the New Millenium , the AASC made use of a series of panel reports that address various aspects of ground- and space-based astronomy and astrophysics. These reports provide in-depth technical detail. Astronomy and Astrophysics in the New Millenium: An Overview summarizes the science goals and recommended initiatives in a short, richly illustrated, non-technical booklet.

Driven by discoveries, and enabled by leaps in technology and imagination, our understanding of the universe has changed dramatically during the course of the last few decades. The fields of astronomy and astrophysics are making new connections to physics, chemistry, biology, and computer science. Based on a broad and comprehensive survey of scientific opportunities, infrastructure, and organization in a national and international context, New Worlds, New Horizons in Astronomy and Astrophysics outlines a plan for ground- and space- based astronomy and astrophysics for the decade of the 2010's. Realizing these scientific opportunities is contingent upon maintaining and strengthening the foundations of the research enterprise including technological development, theory, computation and data handling, laboratory experiments, and human resources. New Worlds, New Horizons in Astronomy and Astrophysics proposes enhancing innovative but moderate-cost programs in space and on the ground that will enable the community to respond rapidly and flexibly to new scientific discoveries. The book recommends beginning construction on survey telescopes in space and on the ground to investigate the nature of dark energy, as well as the next generation of large ground-based giant optical telescopes and a new class of space-based gravitational observatory to observe the merging of distant black holes and precisely test theories of gravity. New Worlds, New Horizons in Astronomy and Astrophysics recommends a balanced and executable program that will support research surrounding the most profound questions about the cosmos. The discoveries ahead will facilitate the search for habitable planets, shed light on dark energy and dark matter, and aid our understanding of the history of the universe and how the earliest stars and galaxies formed. The book is a useful resource for agencies supporting the field of astronomy and astrophysics, the Congressional committees with jurisdiction over those agencies, the scientific community, and the public.

Astronomy is a fun and challenging science for students. This manual is intended for one- and two-semester astronomy courses and uses hands-on, engaging activities to get students looking at the sky and developing a lifelong interest in astronomy.

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 only a tiny fraction of the vast expanse of the universe. In Astronomy’s Limitless Journey, astrophysicist Günther Hasinger takes the reader on a journey to the far reaches of the universe—an exciting time travel that begins with the incredibly hot fireball of the Big Bang roughly 13.8 billion years ago and ends in distant eons with its cold, dark demise. In between lie the times in which extensive structures, galaxies, stars, and planets form. As the field of astrophysics and cosmology experiences a “golden age” due to larger telescopes, faster computers, and more sophisticated algorithms, fundamental changes are taking place in our understanding of space and time and of the origin and future of our universe. Hasinger thoroughly explains these fascinating revelations and describes the methods utilized in modern astrophysics. He cautions, however, that the boundaries between knowledge and ignorance shift constantly; where our knowledge is so incomplete such that we can only speculate, the journey becomes shaky. Indeed, every new discovery opens a further door to the unknown and with every answered question, we discover more locked doors still to be opened.
