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 ...
Our solar system may not be as isolated as we once thought. According to a new study, more than 1 million interstellar objects could be lurking in the outer reaches of our cosmic neighborhood, quietly ...
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 ...

Scientists Think They’ve Uncovered Mysterious Arms Near the Boundary of the Solar System
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 ...
Rocky fireballs like the one that fell over Alberta, Canada last year shouldn't originate from the icy Oort Cloud... but this one apparently did. When you purchase through links on our site, we may ...
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 ...
Inner Oort Cloud objects have perihelia beyond the Kuiper Belt with semi-major axes less than a few thousand au. They are beyond the strong gravitational influences of the known planets yet are ...
A team of astronomers has made a groundbreaking discovery by detecting molecular activity in comet C/2014 UN271 (Bernardinelli-Bernstein)—the largest and second most distantly active comet ever ...
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 ...
