New Horizons made its farewell pass of Pluto and left us with incredible pictures of the dwarf planet to analyze and discuss for years. It has been an incredible experience for all of humanity to see the most distant planet, even if it has been downgraded to dwarf planet.
The pictures have shown surprising geologic activity and Pluto, which was generally considered a bid dead icy rock. Moreover
NASA today also released an image of exotic ice across the dwarf planet’s surface, revealing signs of recent geologic activity – something scientists hoped to find but didn’t expect. Pluto’s heart-shaped region, known as Tombaugh Regio, appears to have flows like glaciers on Earth.
Moreover, the farewell image below showed atmospheric rings taken from around 1.25 million miles (2 million km) from Pluto. The planet has a reddish hue from the hazes detected by the probe — formed when ultraviolet sunlight breaks apart methane gas in the atmosphere. That means that there is also more complex hydrocarbon gases, such as ethylene and acetylene, which in turn cold and form ice particles and hazes. The ultraviolent sunlight chemically converts hazes into tholins, the dark hydrocarbons that color Pluto’s surface. Sputnik Planum is believed to be full of nitrogen, carbon monoxide, and methane ices.
We will be getting new pictures on a weekly basis but for now we can only say Hail Pluto and Bon Voyage New Horizons.
