The second yearbook published by the Astronomische Gesellschaft presents the breadth and depth of current astronomical research. Martin Rees' Schwarzschild Lecture "Is there a massive black hole in every galaxy?" is followed by several extensive surveys of the new research opportunities opening up with the next generation of telescopes, dedicated satellites, and innovative instrumentation. Among others themes, the spectroscopy of SN 198/A, chemically peculiar stars, and extragalactic radio jets are dealt with at length. The volume is rounded off by shorter reviews of up-front research topics ranging from accretion disks and solar physics to cosmic rays and stellar evolution.

Based on field notes made by the author during his own career as an amateur astronomer, this unique guide covers both the traditional and novel approaches to studying the night sky. In addition to the more standard techniques, it discusses the latest modern resources available to today s astronomer, such as personal computers, the Internet, and computerized telescopes. It includes practical advice on aspects such as site selection and weather; provides the reader with detailed instructions for observing the Sun, Moon, planets, and all types of deep-sky objects; and it introduces newer specialities such as satellite observing and the use of astronomical databases. The book concludes with detailed information about 200 stars, clusters, nebulae, and galaxies, suitable for viewing with modest-sized telescopes under suburban conditions. Written to complement How to Use a Computerized Telescope, this book will also appeal to astronomers with more traditional equipment.

This richly illustrated book discusses the ways in which astronomy expanded after 1945 from a modest discipline to a robust and modern science. It begins with an introduction to the state of astronomy in 1945 before recounting how in the following years, initial observations were made in hitherto unexplored ranges of wavelengths, such as X-radiation, infrared radiation and radio waves. These led to the serendipitous discovery of more than a dozen new phenomena, including quasars and neutron stars, that each triggered a new area of research. The book goes on to discuss how after 1985, the further, systematic exploration of the earlier discoveries led to long-term planning and the construction of new, large telescopes on Earth and in Space. Key scientific highlights described in the text are the detection of exoplanets (1995), the unexpected discovery of the accelerated expansion of the Universe (1999), a generally accepted model for the large-scale properties of the Universe (2003) and the ΛCDM theory (2005) that explains how the galaxies and stars of the present Universe were formed from minute irregularities in the (almost) homogenous gas that filled the early Universe. All these major scientific achievements came at a price, namely the need to introduce two new phenomena that are as yet unexplained by physics: inflation and dark energy. Probably the deepest unsolved question has to be: Why did all of this start with a Big Bang?

It has taken modern science more than 3,500 years, and the genius of such men as Einstein to catch up with what Abraham and Moses knew so long ago. We can only ponder how many more wonders of God may be hidden in the astounding translations of Joseph Smith. In Joseph Smith and Modern Astronomy, Dr. Richard Ingebretsen, former science editor for the Ensign, a medical doctor, and a PhD scientist, confirms the truth of the writings and translations of Joseph Smith using advances in modern science and astrophysics. • Governing stars influence other celestial bodies (Abraham 3:2-4) • The “times” of heavenly bodies are not all the same (Abraham 3:3-4) • Absolute truths have been revealed in the translations of Joseph Smith These fascinating parallels explained by Dr. Ingebretsen will not only broaden your scientific understanding, but they will also present a framework to comprehending other revelations.

The yearbook series Reviews in Modern Astronomy of the Astronomische Gesell three years ago in order to bring the scientific events schaft (AG) was established of the meetings of the society to the attention of the worldwide astronomical community. Reviews in Modern Astronomy is devoted exclusively to the invited reviews, the Karl Schwarzschild lectures, and the highlight contributions from leading scientists reporting on recent progress and scientific achievements at their research institutes. Volume 4 comprises all, eighteen contributions which were presented during the fall meeting of the AG at Preiburg/Breisgau in September 1990. They cover problems in solar research and the solar system as well as the first results of the ROSAT and Hipparcos space missions, stellar and extragalactic studies, and Supernova 1987A in the Large Magellanic Cloud. The Karl Schwarzschild Medal was awarded to Professor Eugene Parker1. His lecture entitled "Convection, Spontaneous Discontinuities, and Stellar Winds and X-Ray Emis·sion" begins this volume.

This 22nd volume in the series contains 15 invited reviews and highlight contributions from outstanding speakers presented during the 2009 annual meeting of the Astronomical Society on the subject of "Deciphering the Universe through Spectroscopy", held in Potsdam, Germany. Topics range from the measurements of magnetic fields on the surface of the sun via detailed measurements of abundances in stellar atmospheres to the kinematics of the universe at its largest scales. The result is a systematic overview of the latest astronomical and cosmological research.
