Equity and inclusion of all in the scientific process would ensure a true diversity of ideas, which is paramount for exploiting the full potential of our community to make new discoveries. Despite this relatively universally accepted Ansatz, women and other under-represented groups still face both direct and indirect obstacles in their pursuit of a career in astronomy and space science. Discrimination based on gender, skin colour, disability, sexual orientation and other minority statuses persists in our society at large but also in the microcosm of astronomy, astrophysics and planetary science communities.
In this Focus issue of Nature Astronomy we put the spotlight on the issue of equity (or lack thereof) in our community by inviting comments on the different manifestations of this persistent discrimination. The data presented by our authors paint a worrying picture. A dense network of often subconscious and therefore insidious biases and discriminatory behaviours lead to very real deficiencies in the representation of women and minority astronomers in almost every aspect of scientific discourse (from conferences to missions, career prizes and citation counts).
The Focus is centred on a research Letter by Neven Caplar and collaborators that asks the question whether women-led papers are cited differently than papers led by men. The answer is yes: with machine-learning techniques accounting for non-gender specific attributes, women-led papers are cited systematically 10% less than their men-led equivalents. This deficit is not surprising and in line with similar findings in other scientific fields. Finally, Chanda Prescod-Weinstein offers her Perspective on the issue of intersectionality and how astronomers at the intersection of multiple minority statuses suffer exponentially more and yet often fall through the cracks of statistical studies such as the one conducted by Caplar et al.
