This first-ever complete map of Jupiter's volcanic moon Io released on March 19, 2012, was created using data and images from NASA's Galileo spacecraft, (which studied Jupiter and its moons between ...

Jupiter’s volcanic moon, Io, is exhibiting geothermal activity far beyond what scientists had anticipated, with heat levels that defy previous models. This extreme thermal activity is driven by the ...

Jupiter’s volcanic moon has always felt like a place that tests your sense of what a world can be. Its surface glows with hundreds of active hot spots. Its mountains rise higher than Everest. Its lava ...

After modeling Europa's conditions, the researchers concluded that its rocky seafloor is likely mechanically too strong to allow for tectonic and volcanic activity. Jupiter's moon Europa is among the ...

NASA has unveiled a breathtaking image of Io, one of Jupiter’s most volatile moons, captured by the Juno spacecraft during a close flyby on December 30, 2023. The detailed imagery provides an ...

While Io, the most volcanically active moon in the solar system, appears completely dry and devoid of water ice, its neighbor ...

How big can volcanic eruptions get on Jupiter’s moon, Io? This is what a recent study published in the Journal of Geophysical ...

A new analysis of data from NASA’s Galileo spacecraft reveals a subsurface “ocean” of magma–either molten or partially molten–beneath the surface of Jupiter’s volcanic moon Io. The finding, from a ...

New research raises doubts about Europa's potential for supporting life, due to the lack of tectonic and volcanic activity on its ocean floor. The strong rocky seafloor possibly limits chemical ...

A new study led by WashU planetary scientists suggests the icy moon lacks the undersea activity needed to support life.
