This week more people in the U.S. will be able to see the Northern Lights, or aurora borealis
this expansion of one of nature's most dazzling spectacles was made possible when a flare of solar energy hit Earth a few days ago and caused a geomagnetic storm that resulted in the Northern Lights illuminating skies at lower latitudes than usual
Their terrestrial landing is made in 21 hours, and as they arrive the plasma increases the geomagnetic field of the planet’s surface. Plasma deflected to Earth's dark side is what triggers auroral displays at poles.
So, thanks to the geomagnetic storm, skywatchers in Scotland, the north of England, and as far south as New York, Wisconsin and Washington state will be able to see the auroras
According to NASA, the Northern Lights are caused by collisions between fast-moving particles (electrons) from space and the oxygen and nitrogen gas in our atmosphere
