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

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’.

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

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

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.

Knowing that these objects are quietly floating just beyond our solar system is both fascinating and humbling. While the risk of a major collision is low, their presence gives us insight into the ...
