Newly released Hubble Space Telescope photos show the distant one-time planet — demoted to "dwarf planet" status in 2006 — is changing color and its ice sheets are shifting.

Whether or not Pluto is considered a planet, it's still interesting. Why is it changing color? Why are the ice sheets shifting? Apparently it has something to do with changing levels of methane which get blown around by solar winds. And the ice sheets changing may have to do with the fact that Pluto's journey around the sun takes so long. Pluto takes 248 years to make it all the way around the sun. So we haven't had the equipment before to see it at this place in it's orbit.
Or maybe Pluto is blushing because it got demoted to a planetoid.
