Okay, own up- who's been burning coal and driving SUVs on Pluto?
The last official planet which comprises our solar system is appearing to warm up, according to astronomers. Astronomers aren't sure why this is occurring, as the planet has been steadily moving away from the sun for nearly a decade.
Normally, the planet is so cold that all but a very minimal amount of atmosphere is forced to freeze and remain on the surface. However, observations are suggesting that the planet's atmosphere remains at least as dense, indicating the warming.
Quick, someone call Al Gore!
