Astronomers might have found evidence of a structure located farbeyond Neptune, potentially giving us clues about the solar system’s primordial past. This discovery involves a dense concentration of ...

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 ...

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 ...

An accidental discovery might change how we think about one of the most mysterious structures in our solar system. The Oort Cloud, a large expanse of icy bodies revolving around the sun at a distance ...

Far beyond Neptune, astronomers have finally confirmed a compact clump of icy worlds hiding inside the Kuiper Belt, a feature they are now calling an inner “kernel.” The tightly packed structure, ...

The Oort cloud is a shell of icy objects that forms the very outskirts of our Solar System. Recently, a group of researchers discovered that the inner portion of the Oort cloud likely has spiral arms ...

Could the icy moons of our solar system hold life beyond our planet? Keith Cooper looks at how planetary scientists plan to find out ...

The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it looks like. Now, new simulations may have given them a first glimpse. When you ...
