Astronomers may have downgraded Pluto to dwarf planet status – not that there is anything wrong with that – but this denizen of the distant fringe of our solar system never stops triggering our imaginations. Check out these images from the Hubble Space Telescope – 384 of them in all – shot between 2002 and 2003.  lead investigator Marc Buie, of the Southwest Research Institute in Boulder, Colorado, calls it his best guess at a true-color appearance” of the dwarf planet. The images also show evidence of ice melting a refreezing as the seasons change – it takes Pluto 248 earth years to make its way around the sun – and you think this winter has been long and cold?
