When NASA’s New Horizons spacecraft sent back the first high-resolution images of Pluto and its moon Charon, scientists quickly realized the outer solar system was more active than they’d previously ...

Charon, Pluto’s largest moon, wears a red cap. Charon’s north pole has a dark red color, starkly different from its otherwise gray-white surface, and scientists have finally found out why. Using a ...

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 ...

In a paper published today in Nature, a team of U.S. scientists led by Dr. S. Alan Stern of Southwest Research Institute (SwRI), concludes that two newly discovered small moons of Pluto were very ...

This close up look at Pluto and Charon, taken as part of the mission's latest optical navigation ("OpNav") campaign from Jan. 25-31, 2015, comes from the Long Range Reconnaissance Imager (LORRI) on ...

One of the many amazing finds of New Horizons was Pluto’s thin atmosphere, and it was even more remarkable when astronomers realized that the dwarf planet was losing less of it than expected. The rest ...

The icy volcanism of Charon may be caused by its internal ocean freezing, expanding, and cracking the outer shell of the moon if it was thinner than expected. When you purchase through links on our ...
