Science by Moonlight

Watch the full video, with images: https://youtu.be/eEbEKXBPfmc

Tonight, a slow and gentle journey around the Moon: how it was born, why it drifts away from us, why it always shows us the same face, its seas of ancient lava and its countless craters, the ice hidden in its shadows, the people and machines that have visited it, the tides it raises in our oceans, and the quiet play of light that gives us its phases and eclipses. There is nothing to remember and nothing to do. Just listen, and drift off.
