NASA: Jupiter moon ‘Ganymede’ with unique magnetic field

spinonews Jupiter moon Ganymede

The largest moon of Jupiter known as Ganymede as it builds its own magnetic field. Scientists discovered it in 1996, believed that it surrounded by a unique magnetic field. Unlike any other planet in our solar system. It has come up with new observations after 20 years.

The Ganymede, which is the only biggest moon in our solar system. As analyzed by the scientists could possibly have a massive liquid ocean sloshing around underneath its surface. It just could be probably a niche in which extraterrestrial life could by sheltering themselves in.


Author Glyn Collinson, the study leader from the Goddard Space Flight Centre of NASA in Greenbelt, Maryland said that they now are going back to over 20 years later in order to have a new look at some of the information, which never was published and finished the story. He further added that they discovered there is an entire piece regarding which no one knew.

In accordance with the newly received results there possibly could be a stormy scenario. As particles flipped off the icy surface of the moon. Due to the coming in plasma rain and severe flows of plasma shoved in between the biggest planet of our solar system and its satellite. Because of an eruptive magnetic occurrence taking place in between the magnetic environments of the two bodies.

The Ganymede has auroras, or more accurately the northern and southern lights. The particles that are responsible for the auroras appear from the plasma that is surrounding the planet.

Auroras of Ganymede

At the time of Galileo’s initial Ganymede flyby the spacecraft fortuitously crossed right over the auroral regions of the Jupiter satellite. As proved by the ions it witnessed raining down onto the surface of the polar cap of the moon.

As believed by the researchers, such findings could prove to be the key components for unveiling the secrets about the moon. Like as to why the auroras of Ganymede are so immensely bright. Planets possessing magnetic environments known as magnetospheres were no doubt revealed and known very well.

But never expected for a moon to possess one. Starting from its arrival at the Jupiter to the year 2000. The Galileo spacecraft made up to six targeted flybys of Jupiter’s moon with numerous instruments. Dedicated to gathering information about the magnetosphere of the moon.

The results also involved the Plasma Subsystem (PLS) of the spacecraft that estimated the temperature, density, and direction of the plasma flowing around the Galileo through the environment.
