Far beyond Neptune, astronomers have finally confirmed a compact clump of icy worlds hiding inside the Kuiper Belt, a feature ...

The newly identified cluster of Kuiper Belt objects lies about 4 billion miles from the Sun, offering fresh clues about how ...

The Kuiper belt, a disc of icy rocks on the outermost edges of the solar system, seems to have more structure than we thought. In 2011, researchers found a cluster of objects there on similar orbits ...

Astronomers at Princeton University have uncovered evidence that the outer solar system is more structured than long believed ...

A brand-new group of frozen objects, orbiting the sun out beyond the distant Kuiper Belt, has been spotted by the Subaru telescope, working with NASA's New Horizons mission to find new targets for the ...

Astronomers have spotted an intriguing cluster of objects in the Kuiper belt, the enormous, donut-shaped region of icy objects beyond the orbit of Neptune. This latest “inner kernel” was identified by ...

The trans-Neptunian region, extending beyond Neptune, represents a primordial reservoir of icy and rocky bodies that have remained relatively unchanged since the Solar System’s formation. Central to ...

New research suggests that a binary pair of Kuiper Belt objects, known as the Altjira system, is actually made up of three separate bodies orbiting one another in a complex triad. This rare orbital ...

The discovery of the Kuiper Belt fundamentally reshaped our understanding of the solar system's architecture and population, revealing a far larger and more complex system than previously imagined.

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...

Somewhere at the edge of the solar system a new Earth-sized world might be lurking, dubbed Planet Y. Astronomers have long proposed that there might be hidden planets beyond the Kuiper belt, a region ...
