The first close-up images of Io since NASA’s Galileo mission in 1997 revealed the emergence of a fresh volcano with multiple lava flows and volcanic deposits covering an area of about 180 ...

Voyager 1 and 2 spacecrafts captured the first close-up images, and then in 1995 Nasa’s Galileo spacecraft flew past Europa taking some deeply puzzling pictures. They showed a surface riddled ...

In the 1990s, NASA's Galileo mission performed magnetic induction measurements that suggested there was such a layer, while more recently, the distribution of volcanoes on Io mapped by NASA's Juno ...
