The aurora borealis isn't able to be seen every day because conditions dealing with sunspots, magnetic storms, and solar winds must all come together so the phenomena can be seen. The phenomena is caused by solar winds striking atomic oxygen particles or nitrogen particles during magnetic storms.
During the summer there's twenty-four hours of day light which awesome. During the winter it's dark enough to see the aurora borealis which is gorgeous.
Continental Drift Theory
Unfortunately, auroras don't occur on a schedule. Aurora borealis are generally associated with coronal mass ejections from the Sun. They are normally visible in northern latitudes above about 40 degrees north, so Canada and the northern US are the best observing locations, plus northern Europe, Iceland, and the northern parts of Russia and Siberia. You can often get a 1-2 day advance notice on spaceweather.com.
It is caused by the showers of particles spraying out of the sun and captured by the magnetic field of the earth. So it is not actually on a regular schedule, and actually is happening constantly, but is best seen at night. The brightness and extent is determined by how charged the particles are. The closer you are to the north magnetic pole the more often you will see it.
Kush was probably a kingdom in parts of present day southern Egypt and Sudan. They don't know for certain where it was, but most scholars think that it was somewhere south of present day Israel. Some say it was Ethiopia, others hold with the Egypt/Sudan theory.
AnswerString theory, which has to date not one single scientific verification has thus nothing whatsoever to do with the creation of the present day universe as it exists in space and time.There is no known way to verify string theory due to things like the incredibly tiny size of the "strings" of energy in string theory. However, if it were true, it may help in understating other theories that relate to how the universe began.
Aurora Borealis for the northern lights and aurora australis for the southern lights. They can be red, blue, green, even violet. They occur in the winter. ADDED: Actually they occur at any time of year. They are not seasonal, but are much more likely to be visible in Winter simply because the skies are darker and for longer each day. I have been lucky enough to see them, while on holiday in Norway, and that in late August.
