"Iron Snowstorms Inside Ganymede May Unlock Secrets of Its Magnetic Mysteries"

Researchers have conducted an experimental study to understand Ganymede's strong magnetic field, testing the 'iron snow' theory which suggests iron crystallizes and falls within the moon's core, similar to a snowglobe. The laboratory experiment used water ice to simulate iron snow crystals and found that crystallization occurs in sporadic bursts when the liquid reaches a supercooled state. This process could explain the dynamic nature of Ganymede's magnetic field and may also apply to other small planetary bodies in the solar system. Earth's core, however, operates differently due to its powerful gravity and material composition.

"Juno's Closest Flyby Unveils Stunning New Views of Jupiter's Volcanic Moon Io"

NASA's Juno spacecraft has captured new high-resolution images of Io, Jupiter's most volcanically active moon, revealing detailed features such as cliffs, mountains, and lava lakes. These images, taken during a close flyby, will help scientists understand the volcanic processes on Io and the influence of Jupiter on its eruptions, providing insights into the formation of the gas giant and its moons. The mission, which has been extended since its 2016 arrival at Jupiter, continues to study the planet and its moons, with another flyby scheduled for February 3.

"Juno's Historic Close-Up Encounter with Jupiter's Volcanic Moon Io Captivates in New NASA Images"

NASA's Juno spacecraft captured unprecedented images of Jupiter's volcanic moon Io during its 57th flyby, coming within 930 miles of the surface. These images, taken on Dec. 30, 2023, provide new insights into Io's volcanic activity and its influence on the Jovian system. The data collected will help scientists understand the frequency and intensity of volcanic eruptions on Io, which is the most volcanic body in the solar system due to intense tidal forces from Jupiter and its other moons. Juno's mission will continue with more flybys until its planned conclusion in September 2025.
