For years, amateur aurora watchers from Canada have noticed mysterious streaks of pale purple and green light that seemed to dance across the nighttime sky. But it wasn’t until 2016 that they shared their colorful images with scientists, who soon identified the lightshow as a new type of upper-atmosphere phenomenon that was jokingly named STEVE. Additional contributions from citizen scientists are now helping researchers identify different types of STEVE emissions and constrain how, and where in Earth’s atmosphere, they’re generated.
