Scientists Gain Insight on Interstellar Magnetic Field at the Edge of Solar System

• http://newstonight.co.za, by Chris Mokaba
 These energy particles were detected for the first time by NASA’s Interstellar Boundary Explorer (IBEX) mission in 2009, which now scientists term as ‘cosmic roadmap’ for galactic magnetic field.

Scientists have been able to determine direction of magnetic field around the solar system by measuring the direction of cosmic rays provided by IBEX and earlier Voyager missions in 2004 and 2007. They are endeavoring to find out effects of magnetic field on the heliosphere, an area which prevents entry of cosmic rays and radiation to pass through it.

Scientists found an area where neutrals ions were highly concentrated and charged particles were losing electrons, leading to change in path of magnetic field. They also found slowing down the speed of incoming particles on striking the band of energy formed by particles released by solar winds at the outer edge of the heliosphere.
