NASA Harnesses Northern Lights

Scientists have harnessed the tools needed to stage Earth’s most colorful light show. They've brought the Aurora Borealis into a lab at NASA’s Langley Research Center in Hampton, Va.
Their simulation, generated by a device called Planeterrella, combines all of the necessary ingredients – a magnetic field, charged particles, and a sphere, to display a colorful reenactment of Earth’s Northern Lights.
Guillaume Gronoff, a research scientist at NASA Langley who lead the creation of Planeterrella, explained, "It recreates the atmosphere of the Earth at 80 km in altitude when an aurora is occurring."
