Caption: Second place in the 2021 IAU OAE Astrophotography Contest, category Galilean moons.

This sequence shows the orbit of the four Galilean moons around the planet Jupiter. Almost two entire orbits of the innermost moon, Io, can be seen, with the other moons (Europa and Ganymede, but in particular Callisto) being further away, orbiting noticeably slower. The images were obtained in 2018 with the Las Cumbres Global Observatory at different locations on Earth, allowing a continuous sequence of images over approximately half a week without gaps during the day. With clear skies and over the course of several nights, the motion of the Galilean moons can also be observed with binoculars (ideally steady your elbows on a surface).

Caption: Secondo posto al concorso di astrofotografia IAU OAE 2021, categoria Lune Galileiane.

Questa sequenza mostra l'orbita delle quattro Lune Galileiane intorno al pianeta Giove. Si possono vedere quasi due intere orbite della luna più interna, Io, mentre le altre lune (Europa e Ganimede, ma in particolare Callisto) sono più lontane e sensibilmente più lente. Le immagini sono state ottenute nel 2018 con il Las Cumbres Global Observatory in diverse località della Terra, consentendo una sequenza continua di immagini nell'arco di circa mezza settimana senza intervalli durante il giorno. In caso di cielo sereno e nel corso di diverse notti, il moto delle Lune Galileiane può essere osservato anche con un binocolo (l'ideale è tenere i gomiti su una superficie).
