NASA's Juno spacecraft recently completed a close flyby of Jupiter's moon, Io, capturing significant data and images.

Io is known for its extreme geological activity with over 400 active volcanoes.

The data from this recent flyby will be compared with previous ones to study variations in Io's volcanic activity.

This is the closest view of Io in over two decades, made possible by Juno's endurance of extreme radiation.

The data gathered will contribute to the understanding of Io's geological processes and provide insights for the study of Jupiter's moon, Europa.

Juno is set to conduct another close flyby of Io in February 2024 before concluding its mission in September 2025.
