The icy volcanism of Pluto's large moon Charon and a belt of fractures across its surface may have been caused by a subsurface frozen ocean bursting through a thin ice shell. New models suggest that ...

For decades, Charon was often viewed as the quieter half of the Pluto system, a frozen world marked by craters, fractures and vast plains. Yet the surface photographed by NASA’s New Horizons ...

This composite of enhanced color images that NASA’s New Horizons mission took when it flew near Pluto (lower right) and Charon (upper left) on July 14, 2015. While Pluto and Charon’s true separation ...

Add Yahoo as a preferred source to see more of our stories on Google. Using the James Webb Space Telescope (JWST), astronomers have detected carbon dioxide and hydrogen peroxide on the frozen surface ...

Recent scientific modeling has proposed a fascinating theory about how Pluto captured its largest moon, Charon. The theory suggests a novel “kiss and capture” event, where the two celestial bodies ...

Since the New Horizons probe flew through the Pluto system on July 14, most of the attention has been on Pluto itself. But it also has a comparatively large and—as we now know—fascinating moon called ...

Charon is large in size relative to Pluto, and is locked in a tight orbit with the dwarf planet. A new simulation suggests how it ended up there. By Jonathan O’Callaghan Some 4.5 billion years ago, ...

In 2015, when NASA's New Horizons spacecraft encountered the Pluto-Charon system, the Southwest Research Institute-led science team discovered interesting, geologically active objects instead of the ...

Scientists have discovered carbon dioxide and hydrogen peroxide on the surface of Charon, Pluto's largest moon, offering clues about the origins of the space rock and other celestial objects in the ...
