While substantial research has focused on emotions within classroom activities such as class attendance, studying, and test-taking, less attention has been paid to emotional experience in informal science settings such as media, museums, and public science events. Despite their significant role, emotions are under-theorised and under-researched in science communication. However, there is a growing interest among researchers and practitioners in understanding their role in the public communication of science and leveraging these insights for more effective science communication. This context lead us to propose and organise this Special Issue on Emotions in Science Communication, comprising six manuscripts as detailed in this editorial.
