Doing so could increase the for scientists and science likelihood that the time and resources we put into communication advance the scientific enterprise.Being truly strategic in science communication likely means communicators starting with the identification of clear, long-term, audience-specific behavioral goals. It should then involve using theory and evidence to prioritize intermediate communication objectives that have the best chance of achieving the identified goals, as well as communication tactics that have the best chance to achieve the prioritized objectives. Tools such as dialogue, storytelling, audience-analysis, and jargon-free communication are useful tactics, but they are not strategies, goals, or objectives. Similarly, increasing scientific knowledge and excitement are often key intermediate objectives but rarely the end-goal of communication.A first step to becoming a more strategic communicator is to understand (a) the difference between long-term behavioral goals and intermediate communication objectives, and (b) the range of communication objectives that communicators can choose. This talk will suggest just two main types of goals and a limited range of objectives that most science communicators need to consider. These two goals include changing either audience or communicator behavior, or legitimacy judgments. Potential communication objectives include evaluative beliefs about the natural world (i.e., scientific knowledge), other people (i.e., trustworthiness, social norms), and behaviors, as well as a range of discrete emotions and frames. Knowing more about goals and objectives enables nuanced, evidence-based, and creative discussions about the infinite range of tactical choices available to science communicators.The talk will be grounded in research conducted by the author and his colleagues over the last decade. This work includes personal interviews and quantitative surveys with scientists, as well as interviews of communication trainers, foundation leaders, fellowship-program managers, and others. The underlying ideas also originate in research about the social psychology of behavior change, trust and fairness. It also draws on thinking about strategic communication and organizational strategy. Two tensions that will be addressed throughout the talk include the ethics of behavior change, and the challenge of goal-setting for scientists focused on basic or discovery science. Keynote Ewine van IAU100: Celebrating a IAU100: Celebrating a century of progress in astronomy: In 2019, the International Astronomical Union (IAU), commemorated itsfoundation a century ago. This was an Dishoeck century of progress in opportunity to celebrate morebroadly the progress in astronomy over the past hundred years and whatour field has brought to society, but also to look ahead and astronomy: reflectcritically on IAU's role for decades to come. Looking back, scientificand technological progress in astronomy has been beyond anythingimagined at the time the IAU was constituted in 1919. What will thenext hundred years bring? How do we engage with other sciences, nowthat our field is becoming more multidisciplinary? How do we convincegovernments and agencies to continue funding the ever more powerfultelescopes and satellites? And how do we continue to inspire andinvolve people worldwide, from young to old, in our exciting adventurethrough space? This talk will present some highlights and lessonslearned of IAU100 as well as a forward look on how the IAU ispositioned to carry out its mission: to promote and safeguardastronomy in all its aspects (including research, communication,education and development) through international cooperation. Keynote Prajval Shastri Our Obligations while Our Obligations while Crafting our Science Communication Practice:Lessons from Investigating Gender Inequity - Astronomy has begun to be acknowledged as a Crafting our Science powerful vehicle that can enable moving towards a better, more equitable world. Concomitantly, however, it is clear from the evidence from across the globe, that Communication the march of time alone will not address the gender gap in particular and the lack of diversity in general within astrophysics, because discrimination against the Practice:Lessons from marginalised is entrenched in the astrophysics enterprise. It therefore becomes an obligation for science communicators to mould our outward sci-com practice, Investigating Gender based on the causality pointed to by the evidence. It further becomes a responsibility to also become critical insiders and drive change within the profession. These Inequity ideas will be expanded upon with evidence and examples from the Indian context. Keynote Travis Rector Astronomy’s place in the Simply put, climate change is currently the most important topic for science outreach. Humanity's response, particularly in the next decade, has critical consequences fight against climate change for what the future will hold. Fortunately astronomy communicators are well positioned to make a difference. We are highly trusted. And we offer a unique and important perspective that can help people understand the problem as well as solutions. Introductory astronomy classes and our public outreach are an effective way to teach climate change because they reach large numbers of people and cover related topics.But we need to recognize that climate change communication is different than the other forms of outreach we do. Climate change is a difficult topic to teach because it spans a wide range of subject areas, from physics to psychology. It is also a controversial topic, meaning that simply knowing the science content is not enough to effectively teach it. In fact, it is now clear that understanding the science is not enough. People largely made decisions about climate change based upon their values and identity. They therefore need to understand how climate change affects things they care about.In my talk I will describe effective methods for teaching climate change in astronomy classes as well as present established strategies for engaging the public. I will also outline ways in which our profession can reduce our carbon footprint. To avoid the worst consequences of climate change, research indicates that humanity must reduce carbon emissions 50% by 2030, and nearly 100% by 2050. I will describe strategies being considered by the American Astronomical Society to meet that goal. Plenary talk Daniel Kerry Jones Inspiration and Engagement Astronomy in southern Africa has a diverse and unique history. On the occasion of the bicentenary of The National Research Foundation’s (NRF) South African Cunnama with Astronomy Through Astronomical Observatory (SAAO) we honour this heritage and early understanding of astronomy through Khoi and San starlore. This occasion grants us the Khoi and San Starlore opportunity to recall our scientific achievements as well as celebrate together our country's rich and varied cultural heritage. The main campus of the SAAO is of international scientific significance and has been the subject of a UNESCO World Heritage Site report. On December 21, 2018, the South African Heritage Resources Agency (SAHRA) officially declared the SAAO a National Heritage Site. It is important that this cultural heritage is not only preserved but incorporated and celebrated in the context of the SAAO site and history. The SAAO is constructing a new Visitors Centre in Cape Town which will house exciting and engaging exhibits showcasing the science and technology of the SAAO and incorporating artworks, informative exhibits and animations based on traditional Khoi and San starlore. The installations and animations will be accompanied by a conceptual write up of each piece provided initially in four languages: Khoekhoegowab, isiXhosa, Afrikaans and English. This multilingual approach to communication and education is at the forefront of inclusivity at the new Visitors Centre, with hopes to expand such offerings in the future into additional national and minority languages. Selected content from the Visitors Centre will also be freely available online. However with internet access being a limitation, screenings of the newly developed resources will take place in key locations throughout the country in order to engage directly with South African communities. Such commitments to sharing these rare resources is key to furthering education in the field of astronomy and supporting local cultural heritage. The combination of African heritage and modern science makes for relevant and enticing content previously divided in our country's history. This project is a collaboration between the SAAO and African Tongue, and is a truly unique partnership between astronomers, professional linguists, artists, as well as remaining mother-tongue speakers of Khoi and San languages in southern Africa. The combination of astronomy, art and starlore in the expression of traditional stories through digital storytelling techniques will undoubtedly serve as an example of inclusivity and celebration of African culture into the 21st century.
