In the frozen outskirts of the solar system, a reddish dwarf planet orbits in silence. Known as Sedna, it is so distant that one trip around the Sun takes more than 11,000 years. For much of that time ...

The James Webb Space Telescope (JWST), operated by NASA, has uncovered intriguing new details about Charon—Pluto’s largest ...

No telescope has basked in the night sky quite like the enormous new Vera Rubin Observatory. Here's what it could reveal about the universe.

Moons including Enceladus, Europa, Titan, and Triton all probably have oceans of water under their surface. And that's not to speak of all the dwarf planets in the Kuiper Belt, including Pluto, many ...

Amazon's next group of Kuiper satellites could soon launch from Florida, propelling the company closer to providing internet ...

But the former is largely depleted of light elements, and the latter is simply too far away—it’d likely take 15,000 years to get celestial bodies from the Oort Cloud to Mars, whereas ...

Fraser has an idea. “If I had to guess, they are probably red and dark and devoid of water ice on the surface, which is quite common in the Kuiper Belt,” he said.

Understanding that could in turn help explain how the objects in the Kuiper Belt came to be. It could even shed light on questions about the beginnings of solar system.

''The Kuiper Belt object (KBO) Arrokoth, the farthest object in the Solar System ever visited by a spacecraft, possesses a distinctive reddish surface and is characterized by pronounced ...

Details about how this process would work, however, remained unclear. Related: Arrokoth the 'space snowman' and other Kuiper Belt objects may be packed with ancient ice Now, we may have some answers.

Arrokoth, a distant object in the Kuiper Belt, contains significant amounts of organic molecules, including complex sugars, giving it the new nickname "Sugar World," a study has reported.

By honing in on Mors-Somnus, a binary pair of icy asteroids that originated within the Kuiper Belt, the James Webb Space Telescope has uncovered secrets surrounding the evolution of Neptune and ...
