NASA’s Juno spacecraft measured heat below Io’s surface for the first time and found temperatures rise sharply just a few feet underground. Io’s surface appears surprisingly smooth and covered in ...

A careful statistical comparison of observations recorded by NASA's Juno mission and the Planetary Science Institute's Io ...

The subsurface findings could transform how scientists study volcanoes across the solar system — including those on Earth.

The observations show that Io's surface is smooth when viewed at long microwave wavelengths.

NASA's Juno mission has provided the first measurements of the temperature below the surface of Jupiter's moon Io, revealing ...

We have just had our closest look at Jupiter’s volcanic moon Io for decades, thanks to NASA’s Juno spacecraft, which passed the moon on 30 December. Juno, which has been orbiting Jupiter since 2016, ...

NASA's Juno spacecraft has provided groundbreaking insights into the subsurface temperatures of Jupiter's moon Io, revealing ...

Nearly all prior observations of Io’s heat have relied on infrared measurements that could detect temperatures only at the ...

A joint US-Russian crew safely returned to Earth after completing their mission. They spent over eight months aboard the ...

Learn how Jupiter's gravitational pull impacts its moon Io, producing strong underground heat that powers hundreds of volcanoes.

It was many years ago now when David Bowie asked if there was life on Mars. Since then, we’ve concluded there isn’t, much to everyone’s disappointment. That left scientists the world over to start ...

The last time a spacecraft got this close to Jupiter’s moon Io was more than 20 years ago, a blink of an eye on a typical geological timescale. Most planetary bodies in our Solar System wouldn’t ...
