James Webb Telescope Captures Rare Infrared Footprints of Io and Ganymede Inside Jupiter’s Auroras
Jupiter produces the strongest auroras in the solar system. These features glow brightly around its poles as energetic particles crash into the giant planet's atmosphere. New observations have now revealed that Jupiter's moons can disturb this glowing display in unexpected ways. Scientists using the James Webb Space Telescope (JWST) have identified unusual "cold footprints" forming inside the auroras. This effect is caused by the interaction between the moons and Jupiter's immense magnetic field.
