The Moon Illusion

I've seen it before, you probably have too: for a few nights out of the summer, the moon appears freakishly huge when it rises. Here's the science behind it, and I wasn't aware that a camera will record the moon at normal size, not bizarrely inflated as we will see it. This is the week to watch for it in North America, and the full moon on Wednesday will hang "lower in the sky than any full moon since June 1987, so the Moon Illusion is going to be extra strong." American moonrise times can be found here. (via MeFi)
