Analysis of data collected by JWST showcases that hazy sky is actively cooling Pluto's atmosphere, according to Space. The cooling was earlier detected in Pluto's mesosphere, the third layer of ...

The James Webb Space Telescope (JWST) has discovered that a hazy sky over frozen Pluto is helping to cool the dwarf planet's atmosphere, while at the same time giving methane and other organic ...

New James Webb Space Telescope data reveal Pluto's high-altitude haze is a key driver of the climate on the dwarf planet, offering clues to Earth's ancient atmosphere.

For the dwarf planet Pluto, however, the predicted temperature based on the composition of its atmosphere was much higher than actual measurements taken by NASA’s New Horizons spacecraft in 2015.

The haze in Pluto's atmosphere was indeed radiating heat, just as the theory suggested it would. But these findings tell us more than how Pluto cools itself.

Pluto's Haze in Bands of BlueThis processed image is the highest-resolution color look yet at the haze layers in Pluto’s atmosphere. Shown in approximate true color, the picture was constructed ...

Using the James Webb Space Telescope, astronomers have discovered carbon dioxide and hydrogen peroxide at the surface of Pluto's largest moon, Charon, potentially shedding light on its origins.

One of humanity’s best telescopes, the James Webb Space Telescope (JWST), recently spied on Charon — the largest moon of Pluto, which is the reigning king of trans-Neptunian objects (TNOs ...

The Pluto-Charon system is located an average of 3.5 billion miles (5.7 billion kilometers) from the Sun, and at that distance Charon’s surface gets down to a frigid –364° F (–220° C).

The James Webb Space Telescope (JWST), operated by NASA, has uncovered intriguing new details about Charon—Pluto’s largest moon—including the presence of previously undetected surface chemicals. This ...
