Since their discovery in 1967, pulsars have provided an unprecedented opportunity to study the extremes of physics. IAU S337 marks the 50th anniversary of their discovery by reflecting on our understanding of these remarkable physical laboratories and looking forward to the exciting opportunities they offer in the coming decades.

Since the discovery of ammonia in the interstellar medium of the Milky Way in 1968, we have identified around 160 complex organic molecules, which help us understand how stars and planets form. IAU S332 describes how such observations, combined with numerical modelling and laboratory astrochemistry, are used to study how the Universe has evolved.

The Sun is an active and variable star; its activity, 'space weather', affects interplanetary space and planetary environments. IAU S335 gives an overview of the advances in space weather, linking research in solar, heliospheric and planetary physics, and emphasizing cross-disciplinary developments for the international space weather community.

While observations of distant galaxies allow us to probe the cosmic past, only our own Galaxy provides a detailed fossil record that reveals its complete formation history. IAU S334 presents a summary of the astrometric, spectroscopic and photometric surveys that will unveil Milky Way's inner- and outermost regions.

Masers are the microwave analogue of lasers. Astronomical sources of natural maser emission include the gas around forming and dying stars, and around supermassive black holes. These bright sources of microwaves are fascinating in their own right and provide unique abilities to probe details of astronomical sources and their environments.

Detecting the weak cosmological radiation emitted billions of years ago, from the time of the first 'stars', is difficult as emission from our Galaxy and other extragalactic sources intervenes. To get a clear view towards the early Universe, we therefore need to study the foreground emission in great detail.

The European Space Agency's Gaia mission is surveying the full sky, measuring the distances and ages of around a billion stars with unprecedented accuracy. IAU Symposium 330 reviews the first two and a half years of Gaia activities and discusses the scientific results derived from the first Gaia data release.

Marking the 30th anniversary of Supernova 1987A, IAU S331 introduces the accumulating knowledge on supernovae in active fields such as stellar evolution and the diversity of supernova progenitors, explosive nucleosynthesis and particle acceleration in extreme environments, and long-standing issues around the origins of heavy nuclei in the Universe.

The variable activity of stars like our Sun on the one hand drives life-sustaining processes on planets but on the other hand can adversely impact planetary environments rendering them uninhabitable. IAU S328 provides expert reviews and topical, multi-disciplinary research for anyone interested in understanding star-planet interactions and habitability.

IAU S322 explores the revolution in our understanding of the Galactic Centre, a unique and extreme environment, driven by novel instrumentation. It addresses the question: are anomalous, non-thermal signals signatures of dark matter or other new physics, or symptoms of the region's unusual astrophysics? Astronomers have much to learn from studying the Inner Galaxy.

Solar activity is of increasing importance in modern society, as many aspects of technology could be affected by eruptive phenomena associated with solar magnetic variability. IAU S327 includes recent results describing the activity of the Sun, and revealing the dynamics of the solar atmosphere with unprecedented temporal and spatial resolutions.

IAU Symposium 329 covers the impact of massive stars, which is felt across many areas of astrophysics, as they are tools to interpret the conditions and processes in different environments. In parallel, new observational data help constrain our theoretical models of massive star birth, evolution and death.

IAU S316 reviews current research on massive star clusters, which are invaluable bridges connecting the interstellar medium, star formation and evolution, the evolution of galaxies, and cosmology. Observers, theoreticians, and modellers discuss controversial topics and planning the next steps in the key open areas.

Astronomy has become data-driven in ways that are quantitatively and qualitatively different from the past. At this pivotal time, this volume brings together astronomers involved in surveys and large simulation projects, computer scientists, data scientists, and companies, to fruitfully exchange ideas, methods, software, and technical capabilities.

Black holes lie at the heart of some of the most fascinating astrophysical phenomena. IAU Symposium 324 gives a fresh review of black hole research, including such topics as gamma ray bursts, tidal disruption events, and active galactic nuclei, for both observers and theorists engaged in these exciting fields.

Planetary nebulae are the spectacular products of the evolution of low- and intermediate-mass stars. IAU Symposium 323 describes their importance as laboratories for the understanding of atomic, molecular, dust, and plasma processes in different cosmic environments and enable the exploration of the physics of stellar and galactic evolution.

IAU S308 marks the centenary of the birth of the Russian cosmologist Yakov B. Zeldovich, whose seminal work paved the way towards understanding the complex web-like structure observed in our Universe. This volume synthesizes the insights obtained from observational and theoretical studies for researchers and students working in this vibrant field.

IAU S317 offers an updated view of the stellar halos of galaxies, from the local universe to more distant systems, discussing differences and similarities among them. It features reviews on state-of-the-art research in galactic archaeology and stellar halos, for researchers with interests encompassing stellar and galactic astrophysics.

The proceedings of IAU S321 summarize our understanding of the rarefied universe. They discuss the most recent advances in studies of the stellar, dust and gas content of galaxy outskirts, going from resolved stellar populations in the Milky Way and in the Local Group out to high-redshift systems.

Asteroids carry the signatures of the evolutionary processes that gave birth to the Solar System and shaped our planetary neighbourhood. IAU Symposium 318 explores the themes of asteroid origins, collisional evolution, orbital evolution, rotational evolution and evolutional coupling, for graduate students and researchers in this diverse field of study.

IAU Symposium 314 provides astronomers who study the early evolution of stars and exoplanets with an abundance of up-to-date information regarding local groups of young stars. In particular, it illustrates how nearby young stars provide by far the best opportunities to study and directly image young, Jupiter-like exoplanets.

Led by members of the IAU's Working Group in Astrostatistics and Astroinformatics, this timely volume addresses the intricate mathematical methods needed to extract scientific insights from large and complicated datasets. An essential text for both astronomers and statisticians, it provides a solid foundation to advance new research methods in cosmology.

IAU S307 presents a summary of new and innovative techniques used to investigate and understand the properties of massive stars, including asteroseismology, spectropolarimetry and interferometry, highlighting synergies between these new techniques and more classical methods.

Honouring Wojtek Dziembowski, a world leader in the study of pulsations, and containing many excellent reviews, this is an important reference source for researchers on solar and stellar pulsations.

IAU Symposium 293 presents state-of-the-art research on the formation, dynamical evolution, interior dynamics, and atmospheric characteristics of extrasolar habitable planets. This comprehensive, up-to-date and technical volume targets those seeking to understand the origin of life and the possibility and detection of life elsewhere in the Universe.

IAU Symposium 304 addresses the most important questions in the area of active galactic nuclei (AGN). Covering an exceptionally broad range of topics, this fresh summary of AGN surveys is especially useful for researchers engaged in this exciting field, helping them plan for future surveys and observations.
