It took a journey of more than nine years and three billion miles (~five billion km), but New Horizons made it all the way to Pluto, and gave us our first up-close look at our Solar System's outermost ...

WASHINGTON, Oct 1 (Reuters) - Observations by the James Webb Space Telescope are giving scientists a fuller understanding about the composition and evolution of Pluto's moon Charon, the largest moon ...

Pluto and Charon’s meet-cute may have started with a kiss. New computer simulations of the dwarf planet and its largest moon suggest that the pair got together in a “kiss-and-capture” collision, where ...

The spacecraft New Horizons sped past Pluto and its moons on July 14, 2015, gathering data from seven onboard instruments. Shortly thereafter, it began offloading that data in a stream of digital bits ...

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, ...

NASA’s New Horizons spacecraft captured this high-resolution, enhanced color view of Pluto’s largest moon, Charon, just before closest approach on July 14, 2015. Scientists have learned that reddish ...

Pluto may be sharing its atmosphere with its largest moon, Charon, creating the visually striking red spot at the satellite's north pole. New research suggests that conditions on the two worlds over ...

This close-up of canyons on Charon was taken by NASA’s New Horizons probe during its flyby last July. The color-coded picture shows elevation data. Serenity Chasma’s depth can exceed 4 miles in some ...

New research suggests that billions of years ago, Pluto may have captured its largest moon, Charon, with a very brief icy "kiss." The theory could explain how the dwarf planet (yeah, we wish Pluto was ...
