Jupiter's volcanic moon Io doesn't appear to have a subsurface ocean of magma, resolving some issues about how Io's volcanoes erupt and raising broader questions about similar magma oceans within ...

During its close flybys, Juno captured high-precision Doppler data, which measured Io’s gravity by tracking how zipping closely to the moon affected the spacecraft’s acceleration. The data was ...

Io’s long-debated magma ocean may not exist. Juno spacecraft data reveals that tidal forces deform the moon differently than expected if a magma ocean were present. Instead, Io’s mantle appears mostly ...

When teachers explain ocean tides, they frequently describe how the moon's gravity pulls on Earth and all of its water. This, they often say, leads to a gravitational imbalance, which stretches ...

Just like hundreds of the volcanoes you see today on Jupiter's hellish moon, Io. But even that's not the ... hurtling by and is trapped by Earth's gravity. As it settles into orbit, halfway ...

Or perhaps more likely, look at under a microscope. The latest candidate for hosting nearby life is Jupiter’s moon, Io. Let’s take a look at what makes Io special, and what we might hope to ...

Although tides are affected mainly by the moon's gravity, gravity from the sun also pulls on the oceans. In fact, the tidal force of the sun is almost half (46%) that of the moon. When the moon ...

Jeff Bezos' rocket company gave NASA a brief taste of the moon's gravity Tuesday, without straying too far from home. Blue Origin launched the 29 lunar technology experiments to the edge of space ...
