At the edge of our solar system, a host of large, icy bodies make up the Oort cloud, which appears to sport two spiral arms reminiscent of a disk-shaped galaxy. New research founded upon a ...

The Oort cloud is thought to be a remnant of the solar system’s formation, a shell of icy debris left over from the chaotic ...

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 ...

which Stern calls the solar system’s attic. The debris cast there by Jupiter may include some lost planets. “I think the Oort cloud will blow our minds,” says Stern. “It will be littered ...

The Oort cloud is a theoretical debris shell at the gravitational edge of the solar system whose origin could shed more light on the source of comets as well as the origin of our neighbouring planets.

One of the great things about astronomy is that it's full of surprises, especially when it comes to comets — you just can't predict when a new one might pop up. But when one does appear, it gets both ...

During the planet formation process, smaller objects — including asteroids and comets — were drawn to the outer edges of the solar system. These became an immense cloud called the Oort cloud.

The edge of the Solar System is a strange place, full of oddities we've only just begun to probe. But perhaps the oddest of all is the Oort Cloud, a vast field of icy debris extending out to 100,000 ...

And tantalizingly, what they found suggests that our solar system may already ... 328 feet in diameter from the nearby system lurking in the Oort Cloud. For reference, 'Oumuamua is believed ...
