Astronomers have discovered strong evidence for the closest supermassive black hole outside of the Milky Way galaxy. This ...

Astronomers used the powerful James Webb Space Telescope to peer into this object flying by itself through our Milky Way ...

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

Astronomers have discovered that the Solar System traversed the Orion star-forming complex, a component of the Radcliffe Wave galactic structure, approximately 14 million years ago. This journey ...

The disc of plasma surrounding the black hole at the heart of the Milky Way is constantly emitting flares both large and small.

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

Moreover, the model accounts for the gravitational influences acting on the Oort cloud, both from within our solar system and from external sources like other stars and the Milky Way galaxy's center.

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 ...
