Title:	Pluto Pictures Show Brighter, Redder Surface - http://news.bbc.co.uk/2/hi/science/nature/8498455.stm
Description:	Photographs of Pluto taken by the Hubble Space Telescope show that the dwarf planet has gotten significantly brighter and redder in a relatively short span of time. Between 2000 and 2002, Pluto reddened quite a bit, and its northern polar region was shown to be much brighter in 2002 and 2003 than it was in 1994. Experts attribute the shifts to so-called seasonal changes, but they are surprised at how rapidly these shifts took place considering the fact that Pluto takes about 248 years to fully orbit the sun.
