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 ...

We typically think of the Oort cloud as scattered ice balls floating far from the sun, yet still tied to it gravitationally. Occasionally, some wayward gravitational perturbation will knock one of ...

What lies beyond Neptune? Is it just empty space… or something far more mysterious? In this video, we explore the fascinating story of the Oort Cloud – a gigantic, icy sphere that surrounds our Solar ...

"It took 35 years to reach interstellar space, but it will take 40,000 years for Voyager 1 to be closer to the star AC +79 ...

The human mind may find it difficult to conceptualize: a cosmic cloud so colossal it surrounds the Sun and eight planets as it extends trillions of miles into deep space. The spherical shell known as ...

For over a century, researchers have been puzzled by strange gravitational forces seemingly pulling on the orbits of Neptune and Uranus in the distant reaches of our solar system. While some have ...

Astronomers have spotted an icy object near Neptune that they say hails from the distant Oort Cloud, the distant reservoir of asteroids that encircles the solar system out beyond the orbit of Pluto.

Today, let's talk about an incredibly mysterious celestial body in the solar system — Sedna. Did you know that it takes Sedna about 11,000 years to complete one orbit around the Sun? It leisurely ...

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 ...
