NASA’s James Webb Space Telescope (JWST), planned for operation in about five years, will have the capability to investigate – and answer – some of the most challenging questions in astronomy. Although motivated and designed to study the very early Universe, the performance of the observatory’s instruments over a very wide wavelength range will allow the world’s scientific community unequaled ability to study cosmic phenomena as diverse as small bodies in the Solar System and the formation of galaxies. As part of preparation to use JWST, a conference was held in Tucson, Arizona in 2007 that brought together astronomers from around the world to discuss the mission, other major facilities that will operate in the coming decade, and major scientific goals for them. This book is a compilation of those presentations by some of the leading researchers from all branches of astronomy. This book also includes a “pre-history” of JWST, describing the lengthy process and some of the key individuals that initiated early work on the concepts that would evolve to become the premier space observatory of the next decade.

Some of us are wondering: how is the universe we live in, how long has it existed and above all how long will it last? Many, on the other hand, prefer not to think about it so much, the answer does not exist and in any case it does not interest us, what surrounds us seems to have always existed and it is not worth asking these questions. However, man has always asked himself these questions since ancient times and many philosophers have filled pages and pages with hypotheses on the possible end of the world. Today we have been able to understand how the universe has evolved up to our days, but the very first moments of its existence remain obscure and above all what could have been before its birth, if there was a before. It is not yet known how the universe could evolve in the future, how it could end and what could exist after its end. In this paper the author tries to give some possible answers and, in order to be able to easily delve into the complex laws that govern the genesis and evolution of the cosmos, at the beginning of this text the theory of relativity is briefly illustrated, that of quanta and the most recent string and loop gravity theories.

This roadmap, released in early 2014, presents a science-driven 30-year vision for the future of NASA Astrophysics that builds on recent remarkable discoveries to address three defining questions: Are we alone? How did we get here? How does the universe work? Enduring Quests * Are We Alone? * The Exoplanet Zoo * What Are Exoplanets Like? * The Search for Life * Activities by Era * How Did We Get Here? * Stellar Life Cycles and the Evolution of the Elements * The Archaeology of the Milky Way and Its Neighbors * The History of Galaxies * Activities by Era * How Does Our Universe Work? * The Origin and Fate of the Universe * Revealing the Extremes of Nature * Listening to the Cosmos * Activities by Era * Public Engagement: Connecting Through Astronomy * The continuum of astronomy learners * Audiences: From online to one-on-one * Realizing the Vision: Notional Missions and Technologies * Formative Era * The Visionary Era * Cross-cutting, Game-changing Technologies * Science Summary * Technology Summary * Daring Visions * Acronyms Seeking answers to these age-old questions are Enduring Quests of humankind. The coming decades will see giant strides forward in finding earthlike habitable worlds (exoEarths), in understanding the history of star and galaxy formation and evolution, and in teasing out the fundamental physics of the cosmos. * Different astronomical phenomena are typically most prominent in distinct regions of the electromagnetic spectrum: young, dust-enshrouded stars in the far-infrared; older stars and galaxies in visible and near-optical wavelengths; star-forming regions in the ultraviolet, and the million-degree gas of galaxy clusters and black hole accretion disks in X-rays. In addition to spanning the electromagnetic spectrum, the roadmap missions will open a revolutionary new window on the cosmos by detecting gravitational waves, ripples of space-time that emanate from colossal events like the merging of two black holes. These scientific investigations and their enabling space missions are described here in three broad categories of time: the Near-Term Era, defined by missions that are currently flying or planned for the coming decade; the Formative Era, with notional missions (referred to here as "Surveyors") that could be designed and built in the 2020s; and the Visionary Era of technologically advanced missions (referred to as "Mappers") for the 2030s and beyond. The past three decades have seen prodigious advances in astronomy and astrophysics. We have discovered thousands of planets around other stars, revealing a startling diversity of planetary systems and demonstrating that our own solar system is one of many billions across the galaxy. We have mapped the life cycle of stars from their formation in nearby stellar nurseries to their sometimes explosive deaths. We have tallied supermassive black holes weighing millions to billions of times the Sun's mass, finding them in the centers of most big galaxies, where they gorge on gas and stars and blast superheated material into their environments. We have traced the growth and transformation of galaxies from young chaotic shreds a billion years after the Big Bang to the majestic forms they display today. We have established, using precision cosmological measurements, a well-tested account of the Big Bang model's underlying physics. The current picture points to a universe where an early epoch of inflation established uniformity over a vast horizon, where dark matter dominates the gravitational forces that provide the underlying framework of cosmic structure, and where dark energy drives expansion at an ever-accelerating rate.

A unique, wide-ranging examination of asteroid exploration and our future in space Human travel into space is an enormously expensive and unforgiving endeavor. So why go? In this accessible and authoritative book, astrophysicist Martin Elvis argues that the answer is asteroid exploration, for the strong motives of love, fear, and greed. Elvis’s personal motivation is one of scientific love—asteroid investigations may teach us about the composition of the solar system and the origins of life. A more compelling reason may be fear—of a dinosaur killer–sized asteroid hitting our planet. Finally, Elvis maintains, we should consider greed: asteroids likely hold vast riches, such as large platinum deposits, and mining them could provide both a new industry and a funding source for bolder space exploration. Elvis explains how each motive can be satisfied, and how they help one another. From the origins of life, to “space billiards,” and space sports, Elvis looks at how asteroids may be used in the not-so-distant future.

The field of astrophysics is in the midst of a technologically driven renaissance, as fundamental discoveries are being made with astonishing frequency. In the last decade, new detectors in space, on earth, and deep underground have, when coupled with the computational power of modern computers, revolutionized our knowledge and understanding of the astronomical world. This is a great time for a student of any age to become acquainted with the remarkable universe in which we live. This volume is a collection of essays, originally presented orally to a diverse group of students and professionals, which reveal the most fertile areas for future study of astronomy and astrophysics. The emphasis of this work is on the clear description of the current state of our knowledge as a preparation for the future unraveling of the mysteries of the universe that appear today as most fundamental and most amenable to solution. A stellar group of astronomers and astrophysicists describes the directions and styles of work that they think are most likely to lead to progress. Bibliographical notes at the end of each presentation provide guidance for the reader who wishes to go more deeply into a given subject. Unsolved Problems in Astrophysics is a uniquely stimulating introduction to some of the most important topics in modern astrophysics.
