The sun, the center of the solar system, continues to fascinate researchers, and NASA has sent a probe to "touch" the massive star. A new study, however, suggests it may have a long-lost twin. The ...

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 ...

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 our sun have had a partner star during the early days of the solar system? A new study suggests our sun may have had a binary companion, like the system of the planet Tatooine from the original ...

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 ...

The Oort cloud, postulated in 1950 by the Dutch astronomer Jan Oort, defines the periphery of the solar system—extending out beyond 100,000 times the Earth-sun separation. It contains billions of icy ...

Scholz's Star, a binary star system, passed through the Oort Cloud approximately 70,000 years ago, potentially dislodging some comets but having a relatively minimal overall impact due to its small ...
