Indian Scientist Detect Crack in Earth's Magnetic Shield

The world’s largest and most sensitive cosmic ray monitor, located in India, has recorded a burst of galactic cosmic rays that indicates a crack in the Earth’s magnetic shield. 
●    The burst occurred when a giant cloud of plasma ejected from the solar corona struck Earth at a very high speed.
●    The GRAPES-3 muon telescope located at the Tata Institute of Fundamental Research’s Cosmic Ray Laboratory in Ooty recorded a burst of galactic cosmic rays last year lasting for two hours.
●    The burst occurred when a giant cloud of plasma ejected from the solar corona, and moving with a speed of about 2.5 million km per hour struck our planet. 
●    Earth’s magnetosphere extends over a radius of a million kilometres, which acts as the first line of defence, shielding us from the continuous flow of solar and galactic cosmic rays.
