Zoom Earth: Website lets you look at live satellite photos of earths surface

This is using GOES imagery for "live" North America which uses multispectral IR for night [1] but True Color for day. Once you pass a certain zoom level, it switches to historical imagery from Microsoft.

Side note, you can receive GOES images straight from the satellite yourself with a $30 SDR, a $30 LNA, and an antenna made from scrap (or ~$100 if you're not handy).

Ah ha that explains it perfectly, thanks.

I've always been curious what a real day+night satellite image looks like. The simulated ones always show urban areas as absurdly bright.

Does anyone have links to satellite imagery that shows the actual full real transition from daytime to nighttime, at a constant camera exposure so without exaggeration?

> constant camera exposure

Sure, just take an image and color the night part completely black. Street lighting is around 10 lux -- sunlight is 100,000 lux.

This isn't constant exposure throughout but at some points you can see the transition pretty clearly such as 21:32, some great shots: https://www.youtube.com/watch?v=NM2wtte1JRE
