Oifu was watching this yesterday evening. I was tired and slept midway. So Oifu wanted to watch with me.
Nice explanation of solar system. Had a model to show how planets move around sun. Showed how Venus goes thru various phases - full half crescent etc. By shining light on it. Light being Sun. And camera placed where earth was. Then showed earth as crescent when viewed from moon.
Showed photos of earth from satellites. Rectangular - so human. With 100? Km resolution could see intelligent form associated with dirt.
Gave good idea of how insignificant earth is in our solar system.
Enjoyed.
