WASHINGTON – Spurned Pluto is changing its looks, donning more rouge in its complexion and altering its iceball surface here and there.
Color astronomers surprised.
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.
The photos, released by NASA Thursday, paint a Pluto that is significantly redder than it had been for the past several decades. To the layman, it has a yellow-orange hue, but astronomers say it has about 20 percent more red than it used to have.
The pictures show icy frozen nitrogen on Pluto's surface growing and shrinking, brightening in the north and darkening in the south. Astronomers say Pluto's surface is changing more than the surfaces of other bodies in the solar system. That's unexpected because a season lasts 120 years in some regions of Pluto.

Global warming is melting Pluto.
