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

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

The discovery of new exoplanets can help scientists understand how planets form and evolve. Scientists from UNSW Sydney have located a potential new exoplanet -- a planet that orbits a star outside of ...

the Milky Way. Now, using a powerful NASA supercomputer called "Pleiades," scientists have discovered yet another spiral structure on the edge of our solar system. The spiral is composed of ...

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 ...

Fig.1: Artistic representation of the Milky Way. The position of the Solar System is pointed by a white row. Our sun and its ...

Most of the long-period comets in the Solar System come from the outer Oort Cloud. The inner region is much more stable. It's ...

The NASA boffins in white coats and thick-rimmed glasses have detected new signals that show the Oort cloud - the spooky ...

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.

The Milky Way's tidal forces may be shaping the Oort Cloud's inner structure into a spiral shape.

The puzzle of predicting how three gravitationally bound bodies move in space has challenged mathematicians for centuries, ...
