A NASA spacecraft made its closest-ever approach to Jupiter's moon Io, coming within 930 miles of the "surface of the most volcanic world," and the space agency released new images of the flyby.

There are new, high-quality images of Jupiter's moon, Io, thanks to the nearest flyby of the celestial body by a spacecraft in decades. NASA released images Saturday taken by the Juno spacecraft ...

The most volcanically active world in the solar system, Jupiter's moon Io, may possess a global ocean of magma underneath its surface, as well as mysteriously warm poles, a new study finds.

That’s because Jupiter is so large that its gravitational pull acts on Io and creates friction, heating it up in a process called tidal heating. Though the surface of the moon is cold ...

Here’s how it works. Io — Jupiter's fifth moon — is the most volcanically active body in the solar system. Io's surface is peppered with hundreds of volcanoes, some spewing sulfurous plumes ...

The hellish surface of a moon of Jupiter known as Io is riddled with hundreds of lava-spewing volcanoes that make the world ...

This particular flyby brought the iconic spacecraft within 920 miles of Io’s surface. The dense moon is the fourth largest satellite within the solar system, and unlike most of Jupiter and ...

The close encounter also shows what appears to be a pair of plumes erupting from the moon’s surface. On Saturday, Juno made the second closest flyby of Io, traveling at a distance of 930 miles ...

made incredibly close flybys of Io in December 2023 and February. The spacecraft zipped within 930 miles (1,500 kilometers) of the moon’s surface, capturing images and data. Together ...

New data from the agency's Jovian orbiter sheds light on the fierce winds and cyclones of the gas giant's northern reaches and volcanic action on its fiery moon. NASA's Juno mission has gathered ...

No moon in our solar system is likely as chaotic as Io, Jupiter’s third largest. The rocky body looks like a pepperoni pizza because of the constant, numerous eruptions on its surface.
