What color is moonlight typically, and what other colors can moonlight look like from our perspective on Earth?

Jupiter’s moon Io may have been volcanically active throughout its life. In this image of Io, taken by NASA’s Juno spacecraft in 2023, a bright volcanic plume can be seen on the left, just ...

These composite views depicting volcanic activity on Io were generated using both visible light and infrared data collected by NASA's Juno spacecraft during flybys of the Jovian moon on Dec. 14 ...

Assuming Io initially held some 20,000,000,000,000,000,000,000 (or 20 sextillion) tons of sulfur, the amount it’s lost so far leaves roughly 200 quintillion to 1.2 sextillion tons of sulfur ...

Because Io is so close to its massive host planet, the moon is subjected to a tremendous gravitational pull as it orbits Jupiter once about every 42 hours, according to the Planetary Society.

Jupiter's moon Io is the solar system's most volcanic body thanks to a gravitational tug of war that rages below its surface. But now scientists know the violent moon has always been this way.

Scientists in Arizona have published a study explaining how Juptier's moon Io (pictured) forms some of the highest mountains in the solar system, dwarfing Mount Everest, which is almost 5.5 miles ...

Io, the innermost of Jupiter's four largest moons, is slightly bigger than Earth's moon. Io is the most volcanically active body in the solar system, bursting with plumes that rise up to more than ...
