Venus is completely covered by a thick cloud layer, of which the upper part is composed of sulphuric acid and some unknown aerosols. The cloud tops are in fast retrograde rotation (super-rotation), but the factors responsible for this super-rotation are unknown. Here we report observations of Venus with the Venus Monitoring Camera on board the Venus Express spacecraft. We investigate both global and small-scale properties of the clouds, their temporal and latitudinal variations, and derive wind velocities. The southern polar region is highly variable and can change dramatically on timescales as short as one day, perhaps arising from the injection of SO2 into the mesosphere. The convective cells in the vicinity of the subsolar point are much smaller than previously inferred, which we interpret as indicating that they are confined to the upper cloud layer, contrary to previous conclusions, but consistent with more recent study.

More men are studying and working in science fields than women. This could be an effect of the prevalence of gender stereotypes (e.g., science is for men, not for women). Aside from the media and people’s social lives, such stereotypes can also occur in education. Ways in which stereotypes are visible in education include the use of gender-biased visuals, language, teaching methods, and teachers’ attitudes. The goal of this study was to determine whether science education resources for primary school contained gender-biased visuals. Specifically, the total number of men and women depicted, and the profession and activity of each person in the visuals were noted. The analysis showed that there were more men than women depicted with a science profession and that more women than men were depicted as teachers. This study shows that there is a stereotypical representation of men and women in online science education resources, highlighting the changes needed to create a balanced representation of men and women. Even if the stereotypical representation of men and women in science is a true reflection of the gender distribution in science, we should aim for a more balanced representation. Such a balance is an essential first step towards showing children that both men and women can do science, which will contribute to more gender-balanced science and technology fields.

Leading academic institutions, governments, and funders of research across the world have spent the last few decades fretting publicly about the need for scientists and research organisations to engage more widely with the public and be open about their research. While a global literature asserts that public communication has changed from a virtue to a duty for scientists in many countries and disciplines, our knowledge about what research institutions are doing and what factors drive their 'going public' is very limited. Here we present the first cross-national study of N = 2,030 research institutes within universities and large scientific organisations in Brazil, Germany, Italy, Japan, the Netherlands, Portugal, the United Kingdom, and the United States of America. We find that institutes embrace communication with non-peers and do so through a variety of public events and traditional news media-less so through new media channels-and we find variation across countries and sciences, yet these are less evident than we expected. Country and disciplinary cultures contribute to the level of this communication, as do the resources that institutes make available for the effort; institutes with professionalised staff show higher activity online. Future research should examine whether a real change in the organisational culture is happening or whether this activity and resource allocation is merely a means to increase institutional visibility.

The COVID-19 global pandemic has transformed the relationship between science and society. The ensuing public health crisis has placed aspects of this relationship in harsh relief; perceptions of scientific credibility, risk, uncertainty, and democracy are all publicly debated in ways unforeseen before the pandemic. This unprecedented situation presents opportunities to reassess how certain disciplines contribute to the public understanding of science. Space education has long provided a lens through which people can consider the intersection of the natural world with society. Space science is critical to understanding how human activity and pollution affect global warming, which in turn, inextricably links it to perceptions of the natural world, environmental change, science communication, and public engagement. The pandemic has caused a dramatic shift in how space education projects connect with public audiences, with participation pivoting to online engagement. This transition, coupled with the renewed societal examination of trust in science, means that it is an ideal time for the field of space education to reflect on its development. Whether it evolves into its own distinct field, or remains an area that straddles disciplinary boundaries, such as science education, communication, and public engagement, are crucial considerations when scientific trust, accountability, and responsibility are in question. This paper describes the current state of space education, recent advances in the field, and relevant COVID-19 challenges. The experience of an international space education project in adapting to online engagement is recounted, and provides a perspective on potential future directions for the field.
