Magnetosphere

An illustraton of 's magnetosphere.

An illustraton of Earth's magnetosphere.

A magnetosphere is an area surrounding a planet in which charged particles are affected by the planet’s magnetic field.

History and specifics[]

Neptune's magnetosphere was unusually dangerous because it and the planet's axis of rotation were out of synch. (TOS novel: Academy: Collision Course)

The magnetosphere of Ohniaka III generated significant electromagnetic interference that blocked sensors. (TNG episode & novelization: Descent)

Bleak Prime had an undulating magnetosphere. (DS9 - Strange New Worlds II short story: "Change of Heart")

Chiaros IV's magnetosphere interfered with communications. (S31 novel: Rogue)

The magnetosphere of Phaedra produced a dramatic aurora borealis. (TNG novel: Grounded)

Ta’ith's magnetosphere was unusually strong for the planet's size. (TTN novel: Fallen Gods)

Talin IV's magnetosphere was difficult to scan through. (TOS novel: Prime Directive)

A star's magnetosphere can protect its system of planets from gamma ray and other radiation from a distant supernova, unless it was nearby or unusually strong. A mass extinction on Earth 500,000 years ago was caused from a supernova 100 light years away that overwhelmed Sol's and Earth's magnetospheres. (STO novel: The Needs of the Many)

In 2020, Colonel Shaun Geoffrey Christopher' Saturn probe mission aboard the UNSS Lewis and Clark involved studying the magnetospheres of Saturn and its moons. (TOS novel: The Rings of Time)

Jupiter's magnetosphere was hazardous enough to prevent most civilian tourist traffic. One such danger was a plasma torus made up of ionized sulfur ejected by Io's volcanoes. Jupiter Outpost 92 orbited just outside of the planet's magnetosphere. (Last Unicorn RPG - Starfleet Academy module: A Cadet's Guide to Sector 001 Earth) The magnetosphere produced upper hybrid resonance instability, interfering with communications and scanners. (TOS novelization: Star Trek Into Darkness)

In the 23rd century, a cosmic dust cloud interfered with the protective nature of Pelos' magnetosphere, triggering plagues and famine on the surface. (DTI novel: Forgotten History)

In 2273, Spock piloted Copernicus into the magnetosphere of the gas giant Rose's Folly III to make repairs and evade a pursuing Orion pirate ship. Proximity to the magnetosphere harmed Trill passenger Audrid Dax, as it interfered with the psychic connections between her and her Trill symbiont. (TOS eBook: The More Things Change)

In 2323, Cardassian Guard warships Daikon and Kashai hid within the magnetosphere of a gas giant's moon. (TLE - Terok Nor novel: Day of the Vipers)

In 2369, a Cardassian ship carrying a fusion bomb exploded in Megara's upper atmosphere. The planet's magnetosphere was affected, producing strange-looking aurorae, but it soon stabilized. (TNG novel: Debtor's Planet)

In 2369, Starfleet discovered Cren Veruda's artificial intelligence entity in the magnetosphere of Uridi'si. (DS9 - Mission Gamma novel: Lesser Evil)

In 2372, Worf modulated the magnetic signature of USS Defiant's shields, matching their polarity to Cha'Xirrac's magnetosphere to disguise their approach. (Day of Honor novel: Armageddon Sky)

In 2383, Montgomery Scott scanned a world's magnetosphere, and seeing that it pulsed like brain waves, deduced that the world was alive. (TNG novel: Indistinguishable from Magic)

Kelvin timeline[]

Interference from Saturn's magnetosphere coupled with that of its moon Titan was able to hide the USS Enterprise from the Narada in 2258. (TOS novelization: Star Trek)

Disruptions in Jupiter's magnetosphere served to mask Section 31's Io Facility and its construction of the USS Vengeance in the 2250s. (TOS novelization: Star Trek Into Darkness)
