Researchers recently confirmed that the aurora-like lights known as STEVE are not actually aurora, but instead a unique phenomenon. The project used a spectrograph to examine the light from the phenomenon and identify what kind of emissions they give and in what patterns and wavelengths. Results could help scientists further understand how space weather affects technology used in processes such as communications between Earth and spacecraft.
