"NASA's Close Encounter: Stunning Images of Volcano-Covered Moon Io"
NASA's Juno spacecraft conducted its second close flyby of Jupiter's moon Io, capturing detailed images of the moon's volcanic activity, including potential plumes of sulfur and sulfur dioxide erupting from its surface. Io, the most volcanic world in the solar system, experiences immense heat and frictional tidal heating due to the gravitational pull of Jupiter and its large moons, resulting in high volcanic activity and an ocean of magma beneath its rocky surface. Juno's next perijove is scheduled for March 7, continuing its exploration of Jupiter's cloud tops, while its scientific instruments have made notable discoveries since the mission began in 2016.
