Early in our Solar System’s history, bits of icy debris were scattered and then gradually coaxed into a spiral alignment in ...

Even the little-understood Oort Cloud, at the outer edges of our solar system beyond view, has a partly spiral structure.

Most of the long-period comets in the Solar System come from the outer Oort Cloud. The inner region is much more stable. It's ...

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.

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 simulation ...

The Oort cloud is traditionally thought of as a vast ... "The disk, when viewed from a distance, would appear as a spiral structure with two twisted arms," the authors wrote.

Hubble’s latest image reveals the Small Magellanic Cloud (SMC), a nearby dwarf galaxy visible from Earth without a telescope.

A recent image from the Hubble Space Telescope captures a gorgeous spiral galaxy bursting with new star formation.

Recently, a group of researchers discovered that the inner portion of the Oort cloud likely has spiral arms that make it look like a galaxy. The arms were brought into existence by “galactic ...

The statistical signs and symbols of a serious inflationary spiral continue to mount. Industrial production figures for January indicate that U.S. plants are operating at near-capacity—meaning ...

Feb. 23 (UPI) --A shell of icy objects at the edge of the solar system known as the Oort cloud has a pair of spiral arms that resemble a miniature galaxy, new research suggests. Until now ...
