Explanation: The Sun is not the quiet place it seems. It expels an unsteady stream of energetic electrons and protons known as the solar wind. These charged particles deform the Earth's magnetosphere, change paths, and collide with atoms in Earth's atmosphere, causing the generation of light in auroras like that visible in green in the image left. Earth itself is also geologically active and covered with volcanoes. For example, Fagradalsfjall volcano in Iceland, seen emitting hot gas in orange near the image center. Iceland is one of the most geologically active places on Earth. On the far right is the Svartsengi geothermal power plant which creates the famous human-made Blue Lagoon, shown emitting white gas plumes. The featured composition therefore highlights three different sky phenomena, including both natural and human-made phenomena.

“Earth itself is also geologically active and covered with volcanoes.”

Damm that Moon. When are they going to do something about that?

I’m assuming that all three were going at the same time, and the photographer didn’t get combine any images. Iceland is an interesting place.
A lot going on there.

Volcanoes need to quit spewing greenhouse gasses and become greenhouse ferns!

The Sun is a vast thermonuclear explosion held together by gravity. Who ever thought of it as "the quiet place"?

What about the light from the city? That should get a mention as well.
