What took pictures of Pluto?
On July 14 the telescopic camera on NASA’s New Horizons spacecraft took the highest resolution images ever obtained of the intricate pattern of “pits” across a section of Pluto’s prominent heart-shaped region, informally named Tombaugh Regio.
Why is Pluto so colorful?
The dark color is believed to be the result methane and nitrogen in the atmosphere interacting with ultraviolet light and cosmic rays, creating the dark particles (“tholins”) common to Pluto. And then there are the “Brass Knuckles”, a series of equatorial dark areas on the leading hemisphere.
When was the first image of Pluto taken?
The Pluto image to the left was taken by the Faint Object Camera of the Hubble Space Telescope in 1994 and is representative of the highest resolution achieved from Earth. The Pluto image to the right was taken by New Horizons just 16 hours before closest approach in July 2015.
How big is the New Horizons image of Pluto?
In the center of this 300-mile (470-kilometer) wide image of Pluto from NASA’s New Horizons spacecraft is a large region of jumbled, broken terrain on the northwestern edge of the vast, icy plain informally called Sputnik Planum, to the right. The smallest visible features are 0.5 miles (0.8 kilometers) in size.
What was the name of the spacecraft that flew by Pluto?
NASA’s New Horizons spacecraft has sent back the first in a series of the sharpest views of Pluto it obtained during its July flyby – and the best close-ups of Pluto that humans may see for decades. Each week the piano-sized New Horizons spacecraft transmits data stored on its digital recorders from its flight through the Pluto system on July 14.
What is the name of the heart of Pluto?
This single color MVIC scan includes no data from other New Horizons imagers or instruments added. The striking features on Pluto are clearly visible, including the bright expanse of Pluto’s icy, nitrogen-and-methane rich “heart,” Sputnik Planitia.
