1. 1

    Did you see this weekend’s full Moon? It was unique. Why? Because no two full Moons are exactly alike. To prove it, Laurent Laveder of Quimper, Bretagne, France photographed the last 12 full Moons and stitched the pictures together to make this movie:

    The Moon swells and shrinks, it rocks back and forth and up and down. This is a result of the Moon’s motion around its tilted, elliptical orbit. Each full Moon occurs at a different point in that orbit, and so we see it from a slightly different distance and angle. The rocking motions are called libration; because of them we can see 59% of the Moon’s surface rather than the 50% you might have learned in school. So pay attention to the next full Moon (June 11th). It’s as unique as you are.

    Jazeker! In de goeie ouwe tijd toen er nog geen ruimtesondes waren kon men door dit “gewiebel” geloof ik 60% van het maanoppervlak in kaartbrengen in plaats van de 50% die je in eertste instantie zou bedenken.
