Zodiacal Light

In the mornings, when I'm walking back from the telescope to go to bed, the Zodiacal light is super bright. This is the sun's debris disk. A bunch of particles orbiting the sun, reflecting/scattering light to you. The light follows the ecliptic plane - the plane of the Earth (and other planets) orbits. It looks like a really bright cloud once your eyes adjust to it.

As the light passes through the atmosphere, it gets reddened (just like the setting sun).
