The northern lights, or aurora borealis, offer an entrancing, dramatic, magical display that fascinates all who see it
At the center of our solar system lies the sun, the yellow star that sustains life on our planet. The sun's many magnetic fields distort and twist as our parent star rotates on its axis. When these fields become knotted together, they burst and create so-called sunspots. Usually, these sunspots occur in pairs; the largest can be several times the size of Earth's diameter.
This image from NASA's Solar Dynamics Observatory shows the sun as it appeared in extreme ultraviolet wavelengths on March 5, 2012 just after a major solar flare.
At the center of the sun, the temperature is 27 million degrees Fahrenheit (15 million degrees Celsius). As the temperature on its surface rises and falls, the sun boils and bubbles. Particles escape from the star from the sunspot regions on the surface, hurtling particles of plasma, known as solar wind, into space. It takes these winds around 40 hours to reach Earth. When they do, they can cause the dramatic displays known as the aurora
Auroras occur not only on Earth, but also on other worlds in our solar system (and perhaps exoplanetsas well). The gas giants in our solar system (Jupiter, Saturn, Uranus and Neptune) each have thick atmospheres and strong magnetic fields, and each have auroras — although these auroras are a little different from Earth's, given they are formed under different conditions.

Aurora Borealis one of the two types of natural light display in the Earth's sky, predominantly seen in the high-latitude regions (around the Arctic and Antarctic). Aurora Borealis is seen in the northern hemisphere whereas Aurora Australis is seen in the southern hemisphere
