Scientists and the public are getting their first look at what NASA's New Horizons spacecraft saw as it whirled past Pluto Tuesday morning. Some of the first photographs are revealing amazing things about the solar system's most distant celestial body.

Digital reams of data and photography are being received from New Horizons...

(Grunsfeld) "But frankly we're just skimming the top of it. There's a lot."

NASA's John Grunsfeld and the science teams reviewing it all say Pluto isn't entirely what they expected. Its got a smoother surface, with active geology. Alice Bowman with Johns Hopkins University says it's certainly unique.

(Bowman) "We'll probably end up pulling it apart and say this part resembles that on this world, but there's nothing like it."

NASA is still downloading the data and is expecting have more photos to release on Friday.
