Night sky and space: from the stars to Earth's lights

The Milky Way rises between mountains and is reflected in a lake.

A starry sky and lights on the far shore mirrored on a calm fjord.

A night sky full of stars above desert dunes.

Circular star trails captured in a long-exposure photograph.

The Milky Way above Earth's atmospheric glow, seen from the space station.

Green auroras ripple above the night side of Earth.

A bright green aurora curling above the clouds, seen from orbit.

Italy's boot shape outlined by city lights, seen from space at night.
