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 ...

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

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

Zebra mussels, an aquatic invader from Eurasia, continue their continental spread after arriving in North America. These tiny ...

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, ...

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

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

NASA's Juno mission has made its 51st close flyby of Jupiter, catching stunning images of its moon Io, in the process. Juno flew past Io on Tuesday, May 16, on a flyby that brought it closer to the ...

The spacecraft came to within 930 miles of Io's surface—the closest any spacecraft has flown by the Jovian moon in over 20 years. Reading time 2 minutes The mutilated surface of Jupiter’s moon Io was ...

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 ...
