This video is a part of a series looking at the Outer Solar System. The Oort Cloud is believed to be a vast cosmic shell at the edge of our Solar System that astronomers have never directly seen. The ...

The stars as seen from Earth would have looked dimmer 14 million years ago, as the solar system was in the middle of passing ...

Using a NASA supercomputer to run models, researchers led by SwRI astronomer David Nesvorny now believe that the Inner Oort cloud looks like a spiral disk, around 0.24 light-years across, with two ...

The Oort cloud is a shell of icy objects that forms the very outskirts of our Solar System. Recently, a group of researchers ...

Astronomers believe they've discovered a spiral structure inside the Oort cloud that surrounds our solar system.

Venus, the solar system's shiniest planet, reflects 75% of the sunlight. Scientists believe the planet's mirror-like quality is due to the composition of its atmosphere. The metallic clouds that ...

The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it ...

Previous research has suggested that the Oort cloud contains remnants of the solar system's planets, which were formed over 4 billion years ago, but its exact shape and structure have been a mystery.

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 ...

Uranus, the seventh planet from the sun, has held a vital (and smelly) secret of the solar system for decades ... in Uranus's cloud tops," according to a press release from Gemini Observatory ...

While the composition of gas and dust in a precursor molecular cloud is fairly uniform before ... of the gas and ice giants in the outer solar system. This first-order model of planetary growth ...

Narrator: Serious scientists, like myself, believe our solar system was formed by the collapse of a giant cloud of gas and rock and is held together by the gravitational pull of the Sun.
