Planet Earth at Night with Stars & Airglow | International Space Station
Expedition 74 flight engineer and European Space Agency astronaut Sophie Adenot: "Did you know that you can observe the International Space Station with the naked eye? From the ground, the Station appears as a very bright star that crosses the sky at roughly the speed of a commercial airliner. But unlike an airplane, it has neither headlights nor flashing navigation lights. It's its solar panels, oriented to receive sunlight, that make it so bright when you see it from Earth."
"To find out when we're passing over your heads and where to look for us in the sky, head to the site http://spotthestation.nasa.gov… I won't be able to see you, even if you wave vigorously, but I'm thinking of you from up here!"
You will notice layers of yellow, orange, and green airglow in this video. Airglow occurs when atoms and molecules in the Earth's upper atmosphere, excited by sunlight, emit light to shed their excess energy. Or, it can happen when atoms and molecules that have been ionized by sunlight collide with and capture a free electron. In both cases, they eject a particle of light—called a photon—in order to relax again. The phenomenon is similar to auroras, but where auroras are driven by high-energy particles originating from the solar wind, airglow is energized by ordinary, day-to-day solar radiation.
