Images of an icy world that grew fascinating and complex every day had kept scientists glued to NASA’s unmanned New Horizons spacecraft that made a historic Pluto flyby on July 14. Pluto is just becoming more and more intriguing than ever.

Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune. It was the first Kuiper belt object to be discovered. It is the largest and second-most-massive known dwarf planet in the Solar System and the ninth-largest and tenth-most-massive known object directly orbiting the Sun.

More on Pluto is coming in with NASA spotting ice on Pluto s Cthulhu stretches. It is one of Pluto’s most identifiable features and stretches nearly halfway around Pluto’s equator, starting from the west of the great nitrogen ice plains known as Sputnik Planum.

NASA s associate administrator John Grunsfeld in a prepared statement, had earlier said, We knew that a mission to Pluto would bring some surprises, and now, 10 days after closest approach, we can say that our expectation has been more than surpassed. With flowing ices, exotic surface chemistry, mountain ranges, and vast haze, Pluto is showing a diversity of planetary geology that is truly thrilling.

Measuring approximately 1,850 miles (3,000 kilometers) long and 450 miles (750 kilometers) wide, Cthulhu is a bit larger than the state of Alaska.

Cthulhu’s appearance is characterized by a dark surface, which scientists think is due to being covered by a layer of dark tholins complex molecules that form when methane is exposed to sunlight. Cthulhu’s geology exhibits a wide variety of landscapesfrom mountainous to smooth, and to heavily cratered and fractured.

The reddish enhanced color image shown as the left inset reveals a mountain range located in southeast Cthulhu that’s 260 miles (420 kilometers) long. The range is situated among craters, with narrow valleys separating its peaks. The upper slopes of the highest peaks are coated with a bright material that contrasts sharply with the dark red color of the surrounding plains.

Scientists think this bright material could be predominantly methane that has condensed as ice onto the peaks from Pluto’s atmosphere. That this material coats only the upper slopes of the peaks suggests methane ice may act like water in Earth’s atmosphere, condensing as frost at high altitude, said John Stansberry, a New Horizons science team member from Space Telescope Science Institute, Baltimore, Maryland. Compositional data from the Ralph/Multispectral Visible Imaging Camera (MVIC) on NASA’s New Horizons spacecraft, shown in the right inset, indicates that the location of the bright ice on the mountain peaks correlates almost exactly with the distribution of methane ice, shown in false color as purple.

The resolution of the enhanced color image is about 2,230 feet (680 meters) per pixel. The image measures approximately 280 miles (450 kilometers) long by 140 miles (225 kilometers) wide. It was obtained by New Horizons at a range of approximately 21,100 miles (33,900 kilometers) from Pluto, about 45 minutes before the spacecraft’s closest approach to Pluto on July 14, 2015.

My jaw was on the ground when I saw this first image of an alien atmosphere in the Kuiper Belt, said Alan Stern, principal investigator for New Horizons. It reminds us that exploration brings us more than just incredible discoveries it brings incredible beauty.
