Book Description
Astrometry has historically been fundamental to all the fields of astronomy, driving many revolutionary scientific results. ESA's Gaia mission is astrometrically, photometrically and spectroscopically surveying the full sky, measuring around a billion stars to magnitude 20, to allow stellar distance and age estimations with unprecedented accuracy. With the complement of radial velocities, it will provide the full kinematic information of these targets, while the photometric and spectroscopic data will be used to classify objects and astrophysically characterize stars. IAU Symposium 330 reviews the first 2.5 years of Gaia activities and discusses the scientific results derived from the first Gaia data release (GDR1). This significant increase in the precision of the astrometric measurements has sharpened our view of the Milky Way and the physical processes involved in stellar and galactic evolution. To many, the Gaia revolution heralds a transformation comparable to the impact of the telescope's invention four centuries ago.

Book Description
Gaia is an ambitious satellite mission to chart a three-dimensional map of the Milky Way. By measuring the proper motions and parallaxes for a billion stars, Gaia is set to transform the way we study the composition, formation and evolution of our galaxy. Concurrently the LAMOST survey facility in China will make a complementary spectral survey of millions of objects in much of the northern sky. This volume, comprising the reviews and contributed talks presented at IAU Symposium 298, is an up-to-date review of what we know about the Milky Way as a galaxy prior to the launch of Gaia. It covers many topics including the status of dynamical simulations, photometric and spectroscopic surveys, and interstellar matter in the Milky Way, as well as detailed studies of stellar atmospheres. The expert reviews will interest all those working on Milky Way astronomy as well as galaxy formation and evolution.

Book Description
Astrometry - the study of the positions of astronomical objects and how they move across the sky - is a cornerstone of modern astronomy. Pinning down the distances to and motions of stars in our Galaxy is fundamental - it can lead to an understanding of the origin of these stars and how together they affect the evolution of our Galaxy. Similarly, measuring the motions of planets, their satellites and asteroids is crucial to unravelling the origin and evolution of our solar system (as well as to the planning of space missions to explore them). A workshop held jointly by the Royal Greenwich Observatory and the Institute of Astronomy, in Cambridge, offered an unusual opportunity to bring together astronomers from the fields of Galactic and solar system astrometry. Gathered in this volume are the articles they presented. Together, these provide an auspicious review of optical astrometry and our understanding of the evolution of the Galaxy and solar system for graduate students and researchers.

Book Description
IAU C196 coincided with the 8 June 2004 transit of Venus, producing the exciting, eclectic mix that can be found in these proceedings: the amazing history of the English North-country astronomers of the seventeenth century; the AU at a precision of 1.4 m; the explanation for the infamous black drop effect; a possible Mayan observation of a transit of Venus in the thirteenth century; the vexed question of leap seconds and time scales; history, distances, parallaxes, the solar system at exquisite precision and future space missions that will revolutionise astronomy.

Book Description
IAU Transactions are published as a volume corresponding to each General Assembly. Volume A is produced prior to the Assembly and contains Reports on Astronomy, prepared by each Commission President. The intention is to summarize the astronomical results that have affected the work of the Commission since the production of the previous Reports up to a time which is about one year prior to the General Assembly. Volume B is produced after the Assembly and contains accounts of Commission Meetings which were held, together with other material. The reports included in the present volume range from outline summaries to lengthy compilations and references. Most reports are in English.

Book Description
The IAU Centenary Symposium was held at its General Assembly in Vienna in 2018. It starts with plenary lectures, by Malcolm Longair on 100 years of astronomy, astrophysics and cosmology, and by Catherine Cesarsky, who reflects on a century of IAU history. There follows reminiscences from past IAU presidents and general secretaries and presentations on various aspects of IAU history, including some of the famous astronomers who served the Union. The volume then examines the relations between the IAU and different geographical regions, including the issues relating to the Central Powers after World War I, and the "China crisis", when China withdrew from the Union in 1960 and was absent for two decades. The IAU's internal structures and organization are reviewed, along with trends in astronomical publishing and astronomical education. IAU S349 finishes with a vision of the IAU's future from its current president, Ewine van Dishoeck.
