Hope I've put this in the right forum:
(They don't try too hard, or they'd be wondering how ions and stuff get moved about in a magnetic field)There is much that we don’t know about our own planet and our atmosphere. Scientists strive to learn more as a way to not only understand our own planet, but to be able to apply this understanding to planets outside our solar system in a search for life.
tut tut, all this energy what could it be ....?.....
The new region was discovered after Chappell and other researchers pieced together what they call a "natural cycle of energization" that accelerates low-energy ions in the Earth's atmosphere into the higher energy levels found in regions of the magnetosphere.
The warm plasma cloak starts on the night side of the planet and wraps around the dayside according to the researchers. As the cloak reaches the afternoon side of the planet, it gradually fades away. Due to that fact the cloak only surrounds about 3/4 of the planet.
The cloak is fed by the low-energy particles lifted into space over the Earth's poles, carried behind the Earth on its magnetic tail, and then turned 180 degrees by a kink in the magnetic field. The particles are then boosted back towards the Earth into the region called the plasma sheet.
- " a warm plasma cloak"- sounds downright sinister. Wrapping itself around earth. When I got to the bit about "the afternoon" side of the planet, all I could think of was the long dark tea time of the soul ....
