Scientists in California described how to create artificial auroras on Earth . They said a particle accelerator could be sent 185 miles up into space . The particles would then interact with the atmosphere, creating an aurora that is visible from earth.
Scientists in California described how to create artificial auroras on Earth . They said a particle accelerator could be sent 185 miles up into space . It would then fire high-energy beams back at Earth 's atmosphere . This would create auroras to study - and even types of lightning .
