Researchers have published a paper that uncovers the origin and cause of an extreme space weather event that occurred on July 22, 2012, at the sun and generated the fastest solar wind speed ever recorded directly by a solar wind instrument.
Researchers have said that a rapid succession of coronal mass ejections - the most intense eruptions on the sun - sent a pulse of magnetized plasma barrelling into space and through Earth`s orbit.
Scientists are working to determine and to understand the fate of Comet ISON as it moves away from the sun.
