During the International Year of Astronomy in 2009, we initiated a collaboration between astrophysicists in Western Australia working toward building the largest telescope on Earth, the Square Kilometre Array (SKA), and Indigenous artists living in the region where the SKA is to be built. We came together to explore deep traditions in Indigenous culture, including perspectives of the night sky, and the modern astrophysical understanding of the Universe. Over the course of the year, we travelled as a group and camped at the SKA site, we sat under the stars and shared stories about the constellations, and we talked about the telescopes we wanted to build and how they could sit on the Indigenous traditional country. We found lots of interesting points of connection in our discussions and both artists and astronomers found inspiration. The artists then produced <150 original works of art, curated as an exhibition called “Ilgarijiri — Things belonging to the Sky” in the language of the Wadjarri Yamatji people. This was exhibited in Geraldton, Perth, Canberra, South Africa, Brussels, the U.S.A., and Germany over the course of the next few years. In 2015, the concept went further, connecting with Indigenous artists from South Africa, resulting in the “Shared Sky” exhibition, which now tours the ten SKA member countries. The exhibitions communicate astrophysics and traditional Indigenous stories, as well as carry to the world Indigenous culture and art forms. The process behind the collaboration is an example of the Reconciliation process in Australia, successful through thoughtful and respectful engagements, built around common human experiences and points of contact (the night sky). This Commentary briefly describes the collaboration, its outcomes, and future work.

The 15th international conference of the Public Communication of Science and Technology network took place from April 4–6, 2018. Given its location in Dunedin, New Zealand/Ōtepoti, Aotearoa, it was a natural venue for two sessions on communicating science across cultures.

This paper describes community engagement activities with indigenous heritage and archaeology research in the Caribbean. The practice of local community engagement with the archaeological research process and results can contribute to retelling the indigenous history of the Caribbean in a more nuanced manner, and to dispel the documentary biases that originated and were perpetuated from colonial times. From the conception of the ERC-Synergy NEXUS 1492 research project, a key aim has been to engage local communities and partners in the research process and collaboratively explore how the research results can be positively incorporated in contemporary cultural heritage. In the context of community engagement with scientific research, this paper explores the question of who represents a community and highlights key examples in community participation in archaeological research. These examples emphasize participation throughout the research process, from the development of research questions, to data analysis, dissemination and conservation action.

This case study of the development of a cross-cultural museum exhibition illustrates value and difficulties of cross-cultural collaboration. University researchers worked with a class of postgraduate science communication students and designers from the Otago Museum to produce a museum exhibition. ‘Wai ora, Mauri ora’ (‘Healthy environments, Healthy people’) provided visibility and public access to information about Māori work. The exhibition assignment provided an authentic assessment of student work, with a professional output. Working on the exhibition involved cross-cultural communication between Māori and pakehā (non-Māori) and between students and museum professionals. This provided a rich learning experience that took many of the players outside of their comfort zone.

A study in South Africa shed light on a set of factors, specific to this country, that compel South African scientists towards public engagement. It highlights the importance of history, politics, culture and socio-economic conditions in influencing scientists' willingness to engage with lay audiences. These factors have largely been overlooked in studies of scientists' public communication behaviours.

The night skies and the planet on which we live can be inspirational to young and old alike. In the run up to its 200th anniversary in 2020, the U.K.'s Royal Astronomical Society has put together a £1 million scheme to fund outreach and engagement activities for groups that are less well served in terms of access to astronomy and geophysics. This article outlines the projects funded and the impact they are starting to have.

This paper presents the first study ever conducted on the profile of visitors to the Museum of Human Evolution of Burgos (Spain), which exhibits the finds of the Atapuerca archaeo-paleontological sites. The research was guided by the principles of public communication of science and the methodology of the studies on museum visitors. The analysis reveals a positive perception; the Museum is associated with the sites and they are valued as cultural heritage. Complaints are very limited but useful to produce a set of recommendations to further improve the exhibition. In addition, the findings are placed in the context of similar research carried out at other museums in Spain.

We explored the potential of science to facilitate social inclusion with teenagers who had interrupted their studies before the terms set for compulsory education. The project was carried out from 2014 to 2018 within SISSA (International School for Advanced Studies), a scientific and higher education institution in physics, mathematics and neurosciences, and was focused on the production of video games using Scratch. The outcomes are encouraging: through active engagement, the participants have succeeded in completing complex projects, taking responsibilities and interacting with people outside their usual entourage, within a background in which they have been valued and respected.

It can be argued that ethical considerations in science communication are a significantly overlooked area although these considerations are implicit in many ongoing academic debates within the field, and within the practical implications of work which is being both constructed and shared within the discipline. Priest, Goodwin and Dahlstrom's [2018] edited collection, ‘Ethics and Practice in Science Communication’, is therefore a significant step forwards in allowing for contemporary reflection on the ethical considerations currently influencing the field. In shining a light on some of the ethical questions currently concerning the field of science communication, this enjoyable and detailed selection of chapters draws together a number of key examples and authors, to begin to consider such ethical quandaries, as well as identifying spaces, which are primed for further ethical exploration in the future.

Environmental Pedagogies and Practice is divided into four sections: changing environmental pedagogies, teaching practices, examples of transformative approaches and a toolkit of lesson plans. While the book focuses on environmental communication, the chapters offer insights that are also relevant in a range of science communication contexts.
