A Warm Plasma Cloak - New Region Of Magnetosphere Discovered
A detailed analysis of the measurements of five different satellites has revealed the existence of the warm plasma cloak, a new region of the magnetosphere, which is the invisible shield of magnetic fields and electrically charged particles that surround and protect Earth from the onslaught of the solar wind. The study was conducted by a team of scientists headed by Charles "Rick" Chappell, research professor of physics and director of the Dyer Observatory at Vanderbilt University and published this fall in the space physics section of the Journal of Geophysical Research. The northern and southern polar lights – aurora borealis and aurora australis – are the only parts of the magnetosphere that are visible, but it is a critical part of Earth's space environment. read more
