Mathematicians think abstract tools from a field called symplectic geometry might help with planning missions to far-off ...
After the stress of April's eclipse and Mercury retrograde, May brings a welcome calm and social Gemini season.
NASA has revealed animations of the surface of Jupiter's moon Io, made using brand-new data gathered from the far-off moon. Io, which is Jupiter's third-largest moon, features large mountains and ...
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.
Callisto, one of Jupiter's moons, may have ozone, researchers say after successfully simulating its icy surface conditions in a lab 1. Ozone absorbs the Sun’s harmful ultraviolet radiation ...
These resonances expand and contract the surface of Io, which then allows Jupiter’s gravity to heat the interior of the moons, providing the heating needed for Io’s extreme geologic activity.
A new study found the constant presence of sulfur and chlorine isotopes in the atmosphere of Jupiter’s moon–Io. This revealed persistent volcanic activity on the moon for the entirety of the ...
Jupiter is the biggest planet in the solar system and it has a huge number of moons, unlike Earth which has just one. And notably, while the Earth’s satellite is a gentle and unremarkable world ...
The four biggest moons of Jupiter aren't just blurry smudges in Galileo's telescope anymore. The Italian astronomer Galileo Galilei discovered Ganymede, Callisto, Europa and Io back in 1610 ...
NASA’s Juno mission scientists have used complex data collected during two flybys of Jupiter’s third largest moon Io to create animations that highlight this moon’s most dramatic features.
As Jupiter’s innermost large moon, it is subject to an intense gravitational tug-of-war between is massive parent planet and nearby large moons Europa and Ganymede, both of which are locked in ...
But the spacecraft hasn’t only investigated the planet — it has also studied Jupiter’s many moons, like the large Ganymede and the icy Europa. Recently, the spacecraft has been making close ...
