The simulation of the Solar System that came the closest to the observation was the presence of a small planet, between the ...

Scientists have recently focused their telescopes on a mysterious planet drifting through space, a discovery that has ...

Astronomers have recently unveiled the existence of giant planets that defy current models of planetary formation, ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was suspected ...

For centuries our solar system was the only planetary system known to humans. We had no proof other worlds existed beyond those in our own cosmic backyard, and we imagined that if other planetary ...

On October 6 1995, at a scientific meeting in Florence, Italy, two Swiss astronomers made an announcement that would transform our understanding of the universe beyond our solar system. Michel Mayor ...

A mysterious "rogue" planet has been observed gobbling six billion tons of gas and dust a second—an unprecedented rate that blurs the line between planets and stars, astronomers said Thursday.

Conditions in the early universe might have enabled rocky planets with water to form much earlier than anticipated, potentially allowing life to begin sooner too. Astrophysicists studying the early ...

A starshade is nothing more than a material structure with a hole in the middle. It can be placed in front of a telescope to allow it to focus on its target without being blinded by the light of the ...
