Here, we show that the detection of Borisov implies that interstellar objects outnumber Solar system objects in the Oort cloud, whereas the reverse is true near the Sun due to the stronger ...

The Oort Cloud, an expanse of icy bodies in the far reaches of our solar system, is shown here in a scene from "Encounters in the Milky Way," a show at New York City's Hayden Planetarium that spawned ...

The mysterious cloud of space rocks and debris at the edge of the solar system may have spiral arms, making it resemble a mini galaxy, a new study says. The Oort cloud is a theoretical debris shell at ...

Comet C/2022 E3 (ZTF), which is set to make a close approach to the Earth on Wednesday, may have originated in a mysterious cloud at the edge of the solar system. The comet, which may be faintly ...

NASA's Pleiades supercomputer has provided fresh insights into the Oort cloud – a vast, theoretical spherical shell of icy objects that surrounds our solar system. For a long time, the Oort cloud's ...

Meteorites burn up in Earth’s atmosphere on a regular basis, but a space rock that landed in Canada last year threatens to shake up our entire understanding of the solar system. Scientists traced its ...

The cold and mysterious Oort cloud at the edge of our solar system may be hiding a rogue exoplanet, new research suggests. When you purchase through links on our site, we may earn an affiliate ...

A hidden structure at the farthest reaches of our solar system is challenging long-held theories. Using advanced simulations, ...

New research may shine a light on part of outer space's great mysteries: the Oort Cloud. The Oort Cloud is the name given to a theorized group of potentially trillions of icy objects on the edge of ...

While the Voyager spacecraft are constantly traveling out of the Solar System, sometimes they are getting closer to Earth.

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 ...
