[FONT=&quot]Go Humans! We Inadvertently CreatedArtificial Protective Barrier Around Earth, NASA Says[/FONT][FONT=&quot][/FONT]

[FONT=&quot]Sometimes, every so often, the human racegets a little credit. This week, when NASA reported that space probesdiscovered an artificial barrier around Earth that was created purely by humanactivity.[/FONT][FONT=&quot][/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]The barrier is caused by low frequencyradio communications "interacting with particles in space, which resultsin a sort of shield protecting Earth from high energy radiation inspace,".[/FONT][FONT=&quot][/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]This, scientists say, is potentially verygood news, as we could use the barrier to protect Earth from extreme spaceweather resulting from events like coronal mass ejections—huge explosions onthe sun, where plasmas and magnetic field are ejected from its corona, the outermostpart of its atmosphere. These ejections can result in geomagnetic storms, whichhave the potential to knock out communication satellites and power grids.[/FONT][FONT=&quot][/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]NASA scientists detected the barrier withthe Van Allen Probes, which are designed to study electrons and ions in ournew-space environment. Normally, very low frequency (VLF) signals from radiotelescopes are transmitted from the ground and are used to communicate withsubmarines, deep below the surface of the ocean. However, they also end up goinginto the atmosphere.[/FONT][FONT=&quot][/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]The result is a massive “VLF bubble”enshrouding Earth, NASA said. The bubble can be seen high above Earth’s surfacein the space environment surrounding it.[/FONT][FONT=&quot][/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]Further analysis showed the bubble extendsalmost exactly to the inner edge of Van Allen radiation belts. These threebelts are zones of energetic charged particles that come from solar wind—theparticles are then captured and held by Earth’s magnetic field. When the VLFbubble interacts with the radiation belts, it creates the barrier observed.[/FONT][FONT=&quot][/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]The researchers report that without thebarrier, the radiation belt boundary would be far closer to Earth.[/FONT][FONT=&quot][/FONT]

[FONT=&quot]So, go humans![/FONT][FONT=&quot][/FONT]
