I stumbled across this today... and just had to share it.
For those of you that don't know about the Northern Lights, here's
an explanation (borrowed from Sigurdur H Stefnisson's
website):
The auroras exist in the outmost layer of the atmosphere.
They are created by electrically charged particles that make the
thin air shine, not unlike a fluorescent light. They can be seen in
auroral belts that forms 20-25 degrees around the geomagnetic
poles, both the north and the south. The Northern Lights, also
called Aurora Borealis (Southern lights or Aurora Australis in the
southern hemisphere), are one of the most spectacular shows on this
earth. Sometimes they cover almost all of the sky and seem to be
dancing around with such grace and speed that one can only watch in
awe. They are difficult to photograph but Sigurdur H Stefnisson has
mastered techniques not only to capture the Northern Lights but
also some interesting foregrounds in his photographs. He exposes
his shots to show us a tasteful blend of the northern lights and
the world around him.
