A groundbreaking study has unveiled a startling portrait of Jupiter‘s early days, revealing the gas giant was once nearly twice its current size and wielded a magnetic field about 50 times ...

Jupiter’s immense size–about 1,000 Earths could fit inside of it–and its swirling and jiggly Great Red Spot typically get most of the attention. Now, the planet’s northern and southern ...

As on Earth, Jupiter's magnetic field converges at its poles, and as on Earth, this concentration of magnetic field lines drives charged particles toward the polar regions, where they collide with ...

Powerful solar winds squish Jupiter's magnetic field 'like a giant squash ball' Victoria Corless. Thu, April 3, 2025 at 1:00 PM UTC. 3 min read.

So Jupiter and its massive magnetosphere have massive jets, while Mars's modest interaction with the solar wind – lacking a planet-wide magnetic field – has much smaller jets.

For comparison, Jupiter’s magnetic field is 4.3 gauss and Earth’s field strength is only half a gauss, although that is strong enough to orient compasses worldwide. Triggering activity.

And they hint at unusual processes taking place in Jupiter’s strong magnetic field that propagate down to the poles and deep into the atmosphere, far deeper than the magnetic processes that produce ...

In June 2021, NASA's Juno spacecraft flew close to Ganymede, Jupiter's largest moon, observing evidence of magnetic reconnection. A team has used Juno data to examine the electron and ion ...

"This is the first time we've ever seen a thing like this on any outer world." A massive solar windstorm in 2017 compressed Jupiter's magnetosphere "like a giant squash ball," a new study reports ...
