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

Jupiter’s moon Io has been continuously shaped by volcanic activity for billions of years — possibly even for the Solar System’s entire 4.57-billion-year history, a study suggests. The ...

LOS ANGELES, April 30 (Xinhua) -- New data from NASA's Juno mission has shed light on the dynamic atmosphere of Jupiter and the volcanic activity on its fiery moon Io, according to the agency.

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.

Observations made of Jupiter’s moon Io during the Juno mission’s flybys helped astronomers confirm how and why Io became the most volcanic world in the solar system. CNN values your feedback 1.

Io fast facts. Age: Io is about 4.5 billion years old, about the same age as Jupiter. Distance from Jupiter: Io is the fifth moon from Jupiter. Its average orbital distance is about 262,000 miles ...

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.

But the moon’s wild volcanic activity wasn’t detected until Voyager 1 flew by Jupiter and its moons in 1979, revealing Io’s dynamic surface that resembled a pepperoni pizza, Bolton said.

Jupiter moon of Io is famed for its volcanoes. NASA just spotted the most powerful one yet Not only was the hot spot larger than Earth’s Lake Superior, but it also was seen belching out ...

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 ...

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 ...
