Northern Lights color U.S. skies purple and green

Nature once again demonstrated its power. A power that, at times, is devastating. But, on other occasions, it leaves us indelible images in our memory, like today's. Early this morning, Americans were able to see the aurora borealis from various points around the country.

This phenomenon, produced by the collision between the particles recently emitted by the Sun and those already in the magnetic field of our planet, is commonly observed from Alaska, northern Canada, Greenland, Iceland or the Scandinavian countries. This Sunday, the Sun's emission has been more aggressive and produced a greater reaction, a fact that has caused several to be seen in states such as Wyoming, Maine, Utah, Illinois or North Carolina.

The National Weather Service and several citizens have shared on social networks impressive images of the aurora borealis tinting the sky purple and green.
