Also this looks like a time exposure and probably taken around dusk, which helps.

What's the source of this photo? Search doesn't bring it up, but shows a bunch of composite images.

No, its just the camera exposute has been cranked up, and the iso of the sensor has been set to 3000 or something. Must be a large image sensor since the noise is pretty low, the stars are a bit strealy, that means the picture took about a minute of exposure to collect enough light, and the stars moved in that time
