For years, a group of aurora chasers across Alberta have been photographing a curious ribbon of purple and green light in their night skies. Extending for thousands of kilometres and appearing for just a few minutes to an hour at a time, these Alberta Aurora Chasers captured this celestial phenomenon in their photographs not quite knowing what it was.

Eric Donovan, a Professor of Astronomy at the University of Calgary, and Elizabeth MacDonald, a scientist at NASA, told them they had possibly discovered something never studied before. Affectionately calling it Steve, these photographers have captured the attention of the international scientific community and have become citizen scientist celebrities.
