“…When we focus on astronomy-related interactions, the research gap is even more apparent. Informal education in astronomy is conducted in different settings and involves diverse stakeholders, but the area is not well organized or integrated (Marques and Freitas 2016); few studies concern guided interactions (Stroud, Groome, Connolly, and Sheppard 2007), for instance in planetaria, observatories, or astronomy-related museums and science centers. In this group we can also include Marques, Carlin and Moutinho (2020) and Carlin, Marques and Moutinho (2021), who investigate the interaction of an astronomer guide with a child while observing the Sun with a telescope, and Marques, Carlin and Moutinho (2021), who explore the methods and strategies a group of guides use to communicate about astronomical time in planetarium sessions.…”
