It turns out from the latest images of Pluto that development is still on for "fascinating" terrain that suggests the diminutive orb. A new close-up image, captured by NASA's New Horizons spacecraft, shows a vast, craterless plain that appears to be no more than 100 million years old.

The spacecraft has been providing incredible images of Pluto since it went past by the dwarf planet one Tuesday.

The space agency says geologic processes appear to be still shaping the frozen region. Jeff Moore, leader of NASA's New Horizons Geology, Geophysics and Imaging Team, said the task of gaining insight into the terrain is really a tough one.

Researchers were left with an awestruck feeling after vast, craterless, very young plains on Pluto were discovered, thanks to the flyby. Pluto is located in a region of space chock-full of icy objects. The region is called the Kuiper Belt and the New Horizons team is of the belief that it has a role to play in distressing Pluto’s surface.

“I would never have believed that the first close up picture we get of Pluto didn't have a single impact crater on it. That's just astonishing”, said John Spencer, a planetary scientist on the New Horizons mission.

He added that the decade-long, 3.6 billion-mile journey has produced results beyond expectations.

It’s not just bragging rights for a dwarf planet that Pluto's massive ice mountains represent, but an intergalactic Napolean complex too.

Hal Weaver, another new Horizons project scientist, says that this means that water is present there, which has been long suspected by scientists, but never proved.
