Interstellar material has been discovered in our solar system, but researchers continue to hunt for where it came from and ...

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.

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

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 ...

New research suggests the Oort Cloud may have a spiral structure like a mini galaxy. Supercomputer models reveal its ...

DALLASI absolutely love this, it's called an orrery, and it's a little mechanical model of our solar system. You can see the planets here, orbiting the sun as they would do in real life.

The study of the universe is a subject that never ceases to amaze the scientific community. If being able to know what is beyond our atmosphere has been something that has always b ...

An Egyptian astronomer called Ptolemy (AD100-168) described one of the earliest ideas for how the Solar System is structured. Ptolemy’s model and many earlier ideas of the Solar System had the ...

In research highlighted in a new paper, published today in The Astrophysical Journal, Scientia Senior Lecturer Ben Montet and PhD candidate Brendan McKee analysed changes in the timing of a known ...

the researchers who did the new study used data gathered from the orbits of comets and gravitational forces from within and beyond our solar system to create a model of the Oort cloud's structure.
