Scientists came up with an idea for a new method to measure the height of aurora borealis after working on a 3-D movie for a planetarium.They used two digital single-lens reflex (SLR) cameras set 8 km apart to capture 3D images of Northern Lights and determine the altitude where electrons in the atmosphere emit the light that produces aurora.
