Astronomers have identified a quartet of small rocky planets orbiting Barnard's star - one of our closest stellar neighbors - ...

Astronomers have discovered a panoply of new moons orbiting Saturn, bringing the ringed gas giant's total up to 274 moons—far ...

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.

Until now, the shape of the cloud and how it is affected by forces beyond our solar system have not been largely understood. But the new research, published Feb. 16 at arXiv, says the cloud may ...

Once its rings vanish from sight in March 2025, Saturn will look like a pale yellow sphere through most telescopes.

"The Voyagers have been deep space rock stars since launch, and we want to keep it that way as long as possible!" ...

At the edge of our solar system, a host of large, icy bodies make up the Oort ... A Limited View Direct observation of the inner Oort cloud remains difficult. Objects beyond Neptune that orbit the Sun ...

Scientists from UNSW Sydney have located a potential new exoplanet – a planet that orbits a star outside of our solar system – using a technique known as ‘transit timing variation’.
