The rare encounter revealed a distant world with giant ice sheets, mountains, valleys, and terrains unlike any other seen in the solar system. By reexamining those iconic images, scientists believe ...

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 ...

Astronomers have detected carbon dioxide and hydrogen peroxide on the frozen surface of Pluto's largest moon, Charon, using observations from the James Webb Space Telescope. These discoveries add to ...

Pluto’s heart-shaped feature, known as Tombaugh Regio, has captivated scientists and the public alike since its discovery. This striking geological formation offers insights into the unique ...

Evidence for landslides down steep crater walls on Pluto have been found in imagery from NASA's New Horizons mission.

The surface of Pluto is becoming better resolved as NASA’s New Horizons spacecraft speeds closer to its July flight through the Pluto system. A series of new images obtained by the spacecraft’s ...

As part of its extensive slate of observations, the James Webb Space Telescope (JWST) recently took a closer look at Pluto’s moon Charon, where it helped scientists to make a surprising discovery.

University of Maryland astronomers Silvia Protopapa and Douglas Hamilton are among the authors of the first published paper from the New Horizons flyby, which appears in the Oct. 16, 2015, issue of ...

The first observations of Pluto by NASA's James Webb Space Telescope (JWST) reveal dramatic phenomena on its surface, like seasonal cycles of volatile ice redistribution across its surface, and ...

New research suggests Charon's oldest landscapes preserve evidence of early despinning. Tectonic features in Oz Terra indicate a period of faster rotation for the moon. These structures resemble ...

Evidence of the slowing of Charon's spin period (despinning) is recorded in tectonic features on the surface of Pluto's icy moon, according to a modeling study published in Nature Communications. The ...
