Astronomers have spotted an intriguing cluster of objects in the Kuiper belt, an enormous, donut-shaped region of icy objects beyond Neptune.

Far beyond Neptune, at the far outer rim of our Solar System, astronomers have spotted what looks like a hidden “structure” ...

Astronomers might have found evidence of a structure located farbeyond Neptune, potentially giving us clues about the solar ...

Fresh mapping of the outer solar system has revealed a previously unseen pattern in the Kuiper Belt, the icy ring of debris beyond Neptune that has long been treated as a relatively simple torus of ...

New high-contrast images from SPHERE show a stunning variety of debris disks shaped by collisions of tiny planet-building ...

The Oort cloud is traditionally thought of as a vast shell of perhaps trillions of icy objects encasing our solar system, serving as the final boundary between us and the dark reaches of interstellar ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

A vast region of our solar system, called the Kuiper belt, stretches from the orbit of Neptune out to 50 or so astronomical units (AU), where an AU is the distance between Earth and the sun. This ...

"If our solar system is indeed moving this fast, we need to question fundamental assumptions about the large-scale structure of the universe." Astronomers have discovered that the solar system may be ...

Observations with the instrument SPHERE at ESO's Very Large Telescope have produced an unprecedented gallery of "debris disks" in exoplanetary systems.
