Southern Hemisphere View of Milky Way with Airglow | International Space Station

Southern Hemisphere View of Milky Way with Airglow | International Space Station

Expedition 75 commander, flight engineer, and NASA astronaut Jessica Meir: "Southern Hemisphere Milky Way galaxy view from the International Space Station cupola. This 3s exposure series captured two of my favorite cupola views, the particularly dense Milky Way galaxy as seen from the Southern Hemisphere, and the bright, colorful lights of squid fishing boats (here, the bright blue and green lights off the coast of China, Thailand and India). Look at what the light did now!"

"These colors [orange, green and yellow] on the horizon are airglow, a faint emission of light caused by chemical reactions and interactions between UV radiation and gases in our atmosphere (unlike aurora, which is caused by solar wind particles interacting with Earth’s magnetic field, airglow is present everywhere, all of the time. "
