WASHINGTON: New, excessive-decision photographs of the floor of Pluto beamed from NASA’s New Horizons spacecraft reveal unparalleled geographical selection – from hovering mountains to sand dunes to frozen ice floes, scientists stated Saturday.
One outer solar-system geologist, William McKinnon of Washington University in St. Louis, said if the ridges are, in fact, dunes, that would be “completely wild” given Pluto’s thin atmosphere.
“If an artist had painted this Pluto before our flyby, I probably would have called it over the top – but that’s what is actually there”, said Alan Stern, New Horizons’ principal scientist from Southwest Research Institute in Boulder, Colorado.
NASA said New Horizons will continue to send data back to Earth until late next year. The only speculation is that Pluto must have possessed a stronger and denser atmosphere at some point in history.
Scientists and space fans considered the arrival of the New Horizons spacecraft at Pluto system as the beginning of discovering many mysteries associated with the dwarf planet. These images are showing large regions with chaotically arranged mountains, which resemble the terrain of Europa, the icy moon of Jupiter. “It’s a head-scratcher”, McKinnon said in a written statement.
On the other hand, some images show an incredible atmospheric haze that surrounds the planet in several layers.
The footage downloaded this previous week have greater than doubled the quantity of Pluto’s floor seen, at resolutions of about four hundred meters (a quarter mile) per pixel. The haze creates a twilight effect that allows the spacecraft to caught glimpse of places on the night side that the mission team never expected to see.
