NASA's Juno Spacecraft Reveals Unprecedented Detail of Jupiter's Volcanic Moon Io

Closest Flyby in Over Two Decades Unveils Intense Volcanic Activity and Fuels Investigation into Potential Magma Ocean

NASA's Juno spacecraft has captured high-resolution images of Jupiter's moon Io, revealing its intense volcanic activity in unprecedented detail.
The spacecraft flew within 930 miles of Io's surface on December 30, 2023, marking the closest flyby in over two decades.
Io is the most volcanically active body in the solar system, with hundreds of active volcanoes due to the immense gravitational forces exerted by Jupiter and Io's neighboring moons.
Scientists are using the data collected by Juno to study the frequency and intensity of Io's volcanic eruptions, and to investigate the possibility of a subsurface ocean of magma.
Juno is scheduled to make another close flyby of Io on February 3, 2024, and will continue to operate until September 2025.
