Flybys of Jupiter’s moon Io, the only known volcanic world in our solar system, have captured images of a massive lava lake and a towering Matterhorn-like mountain.

NASA's Juno mission has gathered data from Jupiter's third-largest moon Io, revealing details of a lake of lava on its surface.

Two recent flybys of Jupiter’s moon Io by NASA’s Juno spacecraft revealed a couple of stunning surprises: a remarkably steep mountain and islands in the middle of a burbling lava lake.

Lava lakes on Io's surface had previously been found in a few locations, such as the 127-mile-long lake Loki Patera. This study reveals that these lakes are extremely common on the moon, and the ...

Sunlight at Io is far too weak to keep the lava liquid for long, so a crust quickly forms on each lake’s surface. However, JIRAM has shown that in some cases a liquid rim survives around the ...

An artist’s concept of a lava lake on Jupiter’s moon Io called Loki Patera. The image was made using data from the JunoCam imager aboard NASA’s Juno spacecraft.

And it has observed some dramatic features there, like a lake of lava and a large mountain. Even though Jupiter (and Io) are both far from the sun, and therefore receive little heat from sunlight ...

Scientists believe that alien life could exist on Io and that it may be hiding in lava tubes beneath the surface of the Jovian moon. ... and that it features an active lava lake, lava flows, ...

Flybys of Jupiter’s moon Io, the only known volcanic world in our solar system, have captured images of a massive lava lake and a towering Matterhorn-like mountain.

New findings from NASA's Juno probe provide a fuller picture of how widespread the lava lakes are on Jupiter's moon Io and include first-time insights into the volcanic processes at work there.
