INSTANT NEW YORK TIMES BESTSELLER! Join the galactic conversation on the biggest issues in the universe, from the 'most popular scientist in the world' ‘Don't fear change. Don't fear failure. The only thing to fear is loss of ambition. But if you've got plenty of that, then you have nothing to fear at all’ – Neil deGrasse Tyson Neil deGrasse Tyson is arguably the most influential, acclaimed scientist on the planet. As director of the Hayden Planetarium, and host of Cosmos and StarTalk, he has dedicated his life to exploring and explaining the mysteries of the universe. Every year, he receives thousands of letters – from students to prisoners, scientists to priests. Some seek advice, others yearn for inspiration; some are full of despair, others burst with wonder. But they are all searching for understanding, meaning and truth. His replies are by turns wise, funny, and mind-blowing. In this, his most personal book by far, he covers everything from God to the history of science, from aliens to death. He bares his soul – his passions, his doubts, his hopes. The big theme is everywhere in these pages: what is our place in the universe? The result is an awe-inspiring read and an intimate portal into an incredible mind, which reveals the power of the universe to start conversations and inspire curiosity in all of us.

The twentieth century has witnessed the transformation of astronomy from celestial mechanics to astrophysics. While optical telescopes may have presented a peek into the structure of the constituents of the universe, such as stars and galaxies, new windows of observation have revealed far more amorphous objects, from nebulae and sheets to filaments and voids, whose "violent" processes include flares, shocks, accretion disks and jets. In these processes, plasma is often the constituent matter-- as well as the medium through which the astrophysical setting becomes so violent. In this graduate level text, Tajima and Shibata offer a new synthesis starting where classic works on plasma physics left off. Beginning with a view of plasma astrophysics through fundamental processes of quasi-magnetostatic equilibria, quasi-hydrostatic equilibria, and non-equilibria, the authors go on to develop unique approaches to violent astrophysical plasmas-- as opposed to the more quiescent laboratory variety-- and their processes. The text continues with an exploration of the fundamental processes in hydrostatic, magnetostatic, and gravitational objects. The final chapter is devoted to a discussion of the applications of plasma astrophysics to cosmology, anticipating future developments in this exciting field.This text will be of enormous use to graduate-- and some advanced undergraduate-- students, as well as to physicists entering the field of plasma physics.

The cycle of day and night and the cycle of seasons are two familiar natural cycles around which many human activities are organized. But is there a third natural cycle of importance for us humans? On 13 March 1989, six million people in Canada went without electricity for many hours: a large explosion on the sun was discovered as the cause of this blackout. Such explosions occur above sunspots, dark features on the surface of the Sun that have been observed through telescopes since the time of Galileo. The number of sunspots has been found to wax and wane over a period of 11 years. Although this cycle was discovered less than two centuries ago, it is becoming increasingly important for us as human society becomes more dependent on technology. For nearly a century after its discovery, the cause of the sunspot cycle remained completely shrouded in mystery. The 1908 discovery of strong magnetic fields in sunspots made it clear that the 11-year cycle is the magnetic cycle of the sun. It is only during the last few decades that major developments in plasma physics have at last given us the clue to the origins of the cycle and how the large explosions affecting the earth arise. Nature's Third Cycle discusses the fascinating science behind the sunspot cycle, and gives an insider's perspective of this cutting-edge scientific research from one of the leaders of the field.

Written by a 15-year-old high schooler, Astrophysics Simplified: A Simple Guide to the Universe is inspired by books like A Brief History of Time and Astrophysics for People in a Hurry. This is a popular science (science for a general audience) book. It mainly focuses on the major developments in science by Aristotle and Ptolemy to physicists like Stephen Hawking and Richard Muller. The various concepts of physics, like relativity and quantum physics, are explained in this book along with various topics in astrophysics and cosmology. There is limited mathematics in this book, but some major equations are included. I have done so because one cannot grasp the true 'beauty' in physics without seeing the mathematical or abstract parts alongside practical laws. Physics is to mathematics what Tony Stark (Iron Man) is to J.A.R.V.I.S. or F.R.I.D.AY. The groundwork of computations, statistics, simulations etc. is done by F.R.I.D.A.Y. But, the real work of fighting the villains is done by Iron Man.

A good working knowledge of fluid mechanics and plasma physics is essential for the modern astrophysicist. This graduate textbook provides a clear, pedagogical introduction to these core subjects. Assuming an undergraduate background in physics, this book develops fluid mechanics and plasma physics from first principles. This book is unique because it presents neutral fluids and plasmas in a unified scheme, clearly indicating both their similarities and their differences. Also, both the macroscopic (continuum) and microscopic (particle) theories are developed, establishing the connections between them. Throughout, key examples from astrophysics are used, though no previous knowledge of astronomy is assumed. Exercises are included at the end of chapters to test the reader's understanding. This textbook is aimed primarily at astrophysics graduate students. It will also be of interest to advanced students in physics and applied mathematics seeking a unified view of fluid mechanics and plasma physics, encompassing both the microscopic and macroscopic theories.

and In the IAU Symposium of 1979 devoted to interstellar molecules [8]. Excellent relevant monographs [ 9. 10] . related timely proceedings [ 11] . and recently published elementary textbooks [12. 13] further help to define the pedagogical scope of molecular astrophysics. A significant financial investment has been made in the establishment of ground- and satellite-based observationai facilities for molecuiar astrophysical studies. In the coming years. a wealth of experimental data is bound to accumulate. in which connection close interactions between observers. astrophysical modeliers. and molecular physicists and chemists can play a helpful role in analysis and interpretation. In view of the increasing pace of activity in the field of molecular astrophysics. and in the apparent absence of relevant international meetings since the Liege 1977 and IAU 1979 Symposia. it was deemed appropriate and timely by the organizers to hold a workshop in 1984. Consequently. the NATO Advanced Research Workshop. "Molecular Astrophysics State of the Art and Future Directions". was organized and held at Bad Wlndshelm. West Germany. from 8 to 14 July 1984. The choice of speakers and subject matter of the Workshop was largely subjective. but designed to include most of the generally accepted areas of molecular astrophysical study. Workers from the fields of radio. infrared. and uv-optlcal observations. astrophysical modelling. laboratory spectroscopy. reaction chemistry. collision physics. and theoretical molecular physics and chemistry. were Invited to present survey lectures In their areas of speciality.

Astronomy is the field of science devoted to the study of astronomical objects, such as stars, galaxies, and nebulae. Astronomers have gathered a wealth of knowledge about the universe through hundreds of years of painstaking observations. These observations are interpreted by the use of physical and chemical laws familiar to mankind. These interpretations supply information about the nature of these astronomical objects, allowing for the deduction of their surface and interior conditions. The science associated with these interpretations is called astrophysics. An Introduction to Astronomy and Astrophysics offers a comprehensive introduction to astronomy and astrophysics, complete with illustrative examples and illuminating homework problems. Requiring a familiarity with basic physics and mathematics, this undergraduate-level textbook: Addresses key physics concepts relevant to stellar observations, including radiation, electromagnetic spectrum, photometry, continuous and discrete spectrum, and spectral lines Describes instruments used for astronomical observations as well as how the radiation received is characterized and interpreted to determine the properties of stars Examines the structure of stars, the basic equations which explain stars in equilibrium, and the fusion reactions occurring in stellar cores Discusses the evolution of stars, the solar system, the dynamics of galaxies, and the fundamentals of modern cosmology Explores the universe at high redshifts, where it is dominated by objects such as active galaxies Solutions manual and figure slides available with qualifying course adoption An Introduction to Astronomy and Astrophysics teaches students how to interpret the night sky, providing them with a critical understanding of the stars and other heavenly bodies.

Radiative Processes in Astrophysics: This clear, straightforward, and fundamental introduction is designed to present-from a physicist's point of view-radiation processes and their applications to astrophysical phenomena and space science. It covers such topics as radiative transfer theory, relativistic covariance and kinematics, bremsstrahlung radiation, synchrotron radiation, Compton scattering, some plasma effects, and radiative transitions in atoms. Discussion begins with first principles, physically motivating and deriving all results rather than merely presenting finished formulae. However, a reasonably good physics background (introductory quantum mechanics, intermediate electromagnetic theory, special relativity, and some statistical mechanics) is required. Much of this prerequisite material is provided by brief reviews, making the book a self-contained reference for workers in the field as well as the ideal text for senior or first-year graduate students of astronomy, astrophysics, and related physics courses. Radiative Processes in Astrophysics also contains about 75 problems, with solutions, illustrating applications of the material and methods for calculating results. This important and integral section emphasizes physical intuition by presenting important results that are used throughout the main text; it is here that most of the practical astrophysical applications become apparent.

High-energy astrophysics has unveiled a Universe very different from that only known from optical observations. It has revealed many types of objects in which typical variability timescales are as short as years, months, days, and hours (in quasars, X-ray binaries, etc), and even down to milli-seconds in gamma ray bursts. The sources of energy that are encountered are only very seldom nuclear fusion, and most of the time gravitation, a paradox when one thinks that gravitation is, by many orders of magnitude, the weakest of the fundamental interactions. The understanding of these objects' physical conditions and the processes revealed by high-energy astrophysics in the last decades is nowadays part of astrophysicists' culture, even of those active in other domains of astronomy. This book evolved from lectures given to master and PhD students at the University of Geneva since the early 1990s. It aims at providing astronomers and physicists intending to be active in high-energy astrophysics a broad basis on which they should be able to build the more specific knowledge they will need. While in the first part of the book the physical processes are described and derived in detail, the second part studies astrophysical objects in which high-energy astrophysics processes are crucial. This two-pronged approach will help students recognise physical processes by their observational signatures in contexts that may differ widely from those presented here.
