  Jupiter’s Moon Io Shows No Magma Ocean as New Findings Explain Volcanic Eruptions

  NASA's latest findings indicate that Jupiter's volcanic moon Io does not have a global magma ocean beneath its surface, debunking previous theories. This conclusion comes from analysis of data from NASA's Juno spacecraft and archival observations from the Galileo mission. The study suggests that Io's interior is more solid than expected, with volca...

  Asteroid Impact Reoriented Jupiter’s Largest Moon Ganymede 4 Billion Years Ago

  A colossal asteroid impact about 4 billion years ago dramatically altered Ganymede, Jupiter's largest moon. The asteroid, estimated to be 186 miles wide, struck Ganymede with such force that it reoriented the moon and removed a significant portion of its original surface. This impact not only created a massive crater but also affected Ganymede's in...

  Something Crazy Happens To Jupiter's Moon Io For 2 Hours Every Day

  Not to get too partisan or anything, but Jupiter's moons are probably some of the coolest worlds in the solar system. Two of its largest - Europa and Ganymede - likely contain subsurface oceans, providing tempting spots to go looking for life. But while potentially habitable waters may be especially intriguing to us earthlings, Jupiter's innermost ...
