Jupiter’s largest moon, Ganymede, is also its only moon with a strong magnetic field. Now, using thousands of images from the Hubble Space Telescope, scientists have discovered that the ...

In this artist’s concept, the moon Ganymede orbits the giant planet Jupiter. NASA’s Hubble Space Telescope observed aurorae on the moon generated by Ganymede’s magnetic fields.

Jupiter’s radius is around 11 times that of Earth, but it is perhaps 20,000 times more magnetic. This generates an intense radiation environment around the planet.

Jupiter's bright auroras are created by a cosmic game of "tug-of-war" between the planet's rapid rotation and the release of sulfur and oxygen from volcanoes on the planet's innermost moon, Io.

Jupiter hosts the most powerful magnetic field of all the planets in our solar system, cranking out a field close to 20,000 times stronger than Earth's. Juno has braved that magnetic field during ...

Now, scientists say the moon may visibly glow green in the dark as high levels of radiation from Jupiter’s powerful magnetic field interact with its moon’s icy surface. A 2016 artist's concept ...

On Monday, June 7, the spacecraft shot past Jupiter’s Ganymede—the largest moon in the solar system—snapping a few quick but iconic images and taking readings of the moon’s magnetic field ...

Jupiter's magnetic field has changed since the 1970s, and physicists have proved it.That's not exactly a surprise. Earth's magnetic field, the only planetary field for which we have good ongoing ...

Our moon may have once been as hellish as Jupiter's super volcanic moon Io; ... One theory is that they date back about 4 billion years, to when the moon still had a magnetic field of its own, ...

Jupiter's moon Ganymede was hit by an asteroid about 4 billion years ago that was so large the ... It's also the only moon planetary scientists know of with both an atmosphere and a magnetic field.

JUpiter ICy moons Explorer, or JUICE for short, showed off a glimpse of its scientific abilities after deploying its magnetometer boom and recording a blip of its surrounding magnetic field.

Jupiter's magnetic field has changed since the 1970s, and now physicists think they know why it's happening. Skip to main content. ... Giant Volcano on Jupiter Moon Could Erupt Any Day.
