Conditions on Pluto: Incredibly hazy with flowing ice

The team responsible for the New Horizons flyby of Pluto last week released new pictures Friday of the previously unexplored world.

Scientists say layers of haze stretch 100 miles (160 kilometers) into the atmosphere, much higher than anticipated. All this haze is believed to account for Pluto's reddish color.

As for the incredible ice flows, they appear to be relatively recent: just a few tens of millions of years.
