Auroras are not just something that happen on Earth. "These particles are deflected towards the poles of Earth by our planet's magnetic field and interact with our atmosphere, depositing energy and causing the atmosphere to fluoresce," said astronomer Billy Teets, the director of Dyer Observatory at Vanderbilt University in Nashville, Tennessee. The further north you are the more likely you are to see the display, but in the past the northern lights have been seen as far south as Cornwall and Kent. The bulky yarn makes it insanely warm, especially if you live anywhere that you can see the Aurora Borealis in real life.

In the Northern Hemisphere, the phenomenon is called the northern lights (aurora borealis), while in the Southern Hemisphere, it's called the southern lights (aurora australis). Aurorae on Mars have also been seen, but as the 'red planet' does not have a global magnetic field, aurorae behave differently and appear to be far more widespread. $17.37, $19.30 We can relate that to the processes that accelerate auroral electrons in the near earth space, and we can see the evolution of electric currents that flow in the magnetosphere.

Within the auroral zone, it's best to be as far away from city lights as possible to maximize visibility. NASA is also on the hunt for clues about how the northern lights work. "One of the more challenging aspects of nightside aurorae involves the comparison of the aurora borealis with the aurora australis," said Steven Petrinec, a physicist at the aerospace company Lockheed Martin who specializes in magnetospheric and heliospheric physics. A magnetic needle can be disturbed by the Aurora Borealis. These ions can then be pulled upward by electric fields in the aurora and reach altitudes high enough that under some conditions they will be exposed to sunlight.

While solar wind is constant, the sun's emissions go through a roughly 11-year cycle of activity. The Doppler effect for light emission causes a shortening of the wavelength of the emission if the emitting atom or molecule is moving toward the observer, and a lengthening of the wave-length if it is moving away. Launchpad: Aurora Lights: Why They Exist and What Causes Them. Below the altitude of about 59 miles (95 km), collisions are so frequent that the green oxygen line has no chance to be emitted.
