NASA's New Horizons mission recently had a flyby with Pluto and its largest moon, Charon at 7.49 a.m. Eastern Time. The agency also released the first and the closest image of Pluto taken by the New Horizons.

NASA released the image on Thursday morning for what the space science world, has been waiting since long. The image was taken during the New Horizon's closest encounter with the dwarf planet.

The image is a close-up of a section of Pluto's heart shaped region. It showed ice mountains like 'the Rockies', which were almost 3, 000 meters high.

John Spencer, New Horizons co-investigator, during a press conference at the Johns Hopkins Applied Physics Laboratory in Maryland, said, "You could see the APL campus on this kind of image. The most striking thing is that we have not found any impact craters".

He said the image shows that he surface of the dwarf planet is very young, not more than 100 million years old.

Jeff Moore of the New Horizons geology, geophysics and imaging team said in a statement that Pluto's is so far the youngest surfaces they have ever seen in the solar system.

When asked about how the mountains might have formed on the planet, Dr Spenser said that presently they have no idea about what caused the formation of those mountains on the dwarf planet's surface.

Another surprising thing was the images of Charon, Pluto's largest moon. The dwarf planet's largest moon is about 1200 kilometers across, roughly the distance between Sydney and Bundaberg.

The team was surprised seeing that Charon had very few craters.
