Milky Way Rise

This is a beautiful video of the Milky Way rising over the Texas Star Party by William Castleman. One thing is clear: We are sitting on a rotating planet inside a spiral galaxy! (… that has a dusty, active plane!). Oh, and we are near a very bright star, too!

I also suspect that you can see the zodiacal light in the middle frames as that faint triangular band of light extending upward from the horizon, toward the right. Zodiacal light is scattered sunlight from the faint, dusty plane of the solar system and can be seen from very dark skies well after sunset.
