Solar wind

Solar wind, also known as stellar wind, is a stream of charged particles ejected from a star.

In 2268, Black Jack Nova described his ship, the Windjammer, as "...floatin' feather-light on the soft, sweet stellar winds". 

In the 2360s, the USS Copernicus (NCC-58637) was assigned to study solar winds and magnetic fields in several star systems across the Alpha Quadrant.
