'Earth Day' Aurora | International Space Station
Expedition 74 flight engineer and NASA astronaut Jessica Meir: "Looks like Mother Earth is putting her best face forward for Earth Day with some spectacular Aurora Australis, or Southern Lights! I couldn’t look away from the International Space Station cupola window as I witnessed this magnificent Earthly phenomenon dance its magical ballet. Covering a majority of the area I could see, our precious blue gem had turned completely green! Mother Earth is undeniably gorgeous, but she is also utterly fragile. Let’s remember to treat her as well as she has treated us."
"I never saw anything near this scale during my previous mission here on the ISS. That’s because we are currently near a strong peak of the solar cycle, while my first mission coincided with solar minimum."
Also known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.
