Original air date - A lunar lesson with Selwyn Holland

Learning about the Moon in the week of the full moon before Easter. Science and maths educator Selwyn Holland is our guest fielding questions about the origins of the moon, how it effects the tides, and what explains the changing visibility of the moon from Earth. The photos of the Moon on this page were taken by Selwyn Holland from his observatory and you can see more of Selwyn's astrophotography at the Wide Open Air Exchange podcast site.
