Solar storms from our sun often punch into Earth 's magnetic field, or magnetosphere.

A surge of charged particles blasted from the sun and lit up skies as far south as Arizona and Arkansas .

Unconventionally, these particles momentarily switched off our planet's bow shock, an anomaly that opened up a " two -way highway" through which charged particles also flew to the sun.
