Recently I posted on optical illusions ….. well look at this image taken by the US space agency's New Horizons probe …
Just stare for a second or two at the whitest area then blink and stare and it seems to be moving away from you.
Really weird after a bit, and a good example of a natural illusion.

I learned recently that from the time that Pluto was discovered to the time when it was demoted from planet status, it didn't do one revolution of the Sun, which is less surprising when you know that one Pluto year is 248 Earth years.
