MAVEN Detects Auroras During Solar Storm in 2024

The purple color in this animated GIF shows auroras across Mars' nightside as detected by the Imaging Ultraviolet Spectrograph instrument aboard NASA's MAVEN (Mars Atmosphere and Volatile EvolutioN) orbiter. The brighter the purple, the more auroras were present. Taken as waves of energetic particles from a solar storm were arriving at Mars, the sequence pauses at the end, when the wave of the most energetic particles arrived and overwhelmed the instrument with noise. MAVEN took these images between May 14 and 20, 2024, as the spacecraft orbited below Mars, looking up at the nightside of the planet (Mars' south pole can be seen on the right, in full sunlight).
