Does this mean there's a location in space where – on the side of the earth opposite to the sun – the sun's light is focused into a point of extremely high intensity due to the earth's atmosphere acting like a magnifying glass?
If so, that could make for either a very unfortunate surprise (i.e. a spacecraft passing through that point suddenly melting to a crisp) or an interesting source of energy if it could be harnessed.
