2001年2月4日 · The first movie ever made of Jupiter's moon Io while it is in eclipse shows bright spots of hot lava and changes in auroral glows. These images from NASA's Cassini spacecraft provide evidence that the auroras originate in electrical currents that connect Io and Jupiter along magnetic-field lines.

2025年1月9日 · The Jovian moon Io is likely the most geologically active body in the solar system, offering insight into tidal heating, volcanic processes, and other phenomena. However, its location within Jupiter''s radiation belt presents significant engineering challenges that must be addressed to enable future missions to Io.

Europa orbits Jupiter at about 417,000 miles (671,000 kilometers) from the planet, which itself orbits the Sun at a distance of roughly 500 million miles (780 million kilometers), or 5.2 astronomical units (AU). One AU is the distance from Earth to the Sun. Light from the Sun takes about 45 minutes to reach Europa.
