What lies beyond Pluto and the Kuiper Belt? Today we explore the Oort Cloud a vast, invisible shell of trillions of icy ...

NASA's James Webb Space Telescope turned to the famed ringed world of Saturn for its first near-infrared observations of the planet in 2023. The Oort clous is thought to have been formed by remnants ...

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 ...

Astronomers searching for the faintest glimmers of light beyond distant Pluto say they’ve discovered a new dwarf planet – and that this planetoid’s movements hint that an invisible giant planet ...

The boundary of a solar system is not defined by planets, but by gravity. Beyond Pluto and the Kuiper Belt lies the Oort ...

486958 Arrokoth in the Kuiper Belt, previously called 2014 MU69 and nicknamed "Ultima Thule" was the farthest object in the solar system visited by a spacecraft when NASA's New Horizons conducted a ...

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 ...

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 ...

If you’re wondering about the sunny view from the Oort Cloud, that vast sphere of debris that surrounds our solar system, here it is. As we told you yesterday, scientists now believe this remote, cold ...

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 ...
