To help out, scientists at the University of Lancaster run AuroraWatch, which tells you exactly when to look. The second part of the name, Borealis comes from the Greek name for the north wind, Boreas. “What this paper shows is that it’s possible that it is actually the opposite: This reconnection in the magnetotail is actually reducing the asymmetry.”. This phenomenon in the tail is what scientists had thought caused nonmatching northern and southern auroras. I made the above graphic to show what I mean. The simplistic answer is because human eyes can’t see the relatively “faint” colors of the aurora at night. And scientists are still trying to figure out precisely how space weather works and how they can better predict it. Most of the intense shows I have witnessed in Maine, USA have lasted right around a half hour.

In fact, there is a straightforward scientific explanation for the phenomenon. This phenomenon of the lights does not only occur on Earth. New York, An aurora is a natural light display in the sky. Intense aurora displays are generated following massive explosions on the sun, known as coronal mass ejections. The charged particles in the stream interact with the Earth's magnetic field and enter the atmosphere, primarily at high latitudes where the magnetic field emerges nearly vertically from the Earth's surface.

Instead, the new research finds it is differences in pressure being exerted on the magnetotail that cause these auroral differences. Hence, Aurora Borealis literally means the North Dawn.

The aurora borealis is also considered one of the Seven Natural Wonders of the World. The new study shows auroral asymmetry is reduced as tail reconnection progresses. The aurora borealis has been written about and studied for as long as people have been living in and exploring the polar regions and as such, they have been important to people since ancient times and possibly earlier. Cone cells, concentrated in the fovea in the central area of vision, are high resolution and detect color in bright light. But what's stranger is that the asymmetry is caused by the precise inverse of what scientists expected.
It all comes down to Earth's magnetic tail, which is created by interactions between our planet and the sun. Like Aurora, its optical design and unmixing algorithm give scientists remarkable flexibility, enabling the use of a wide array of new fluorochrome combinations without reconfiguring the system for each application.
