"Stunning Infrared Auroras and Airglow Illuminate Earth's Atmosphere"

Scientists have discovered an "invisible" aurora in Earth's atmosphere that glimmers in infrared light. Unlike the colorful Northern Lights, this aurora is completely invisible to the naked eye. It is created by the interaction of energetic cosmic particles and carbon dioxide in Earth's atmosphere. Observing auroras from space provides advantages over ground-based observations, allowing scientists to study auroral activity during daylight and cover a larger portion of the sky. The findings provide new insights into the interaction between the cosmic environment and Earth's upper atmosphere and may help improve space weather forecasts.
