But what if another world lurked in the distant outer reaches of our solar system? There may be more than just comets at the solar system’s extreme edges, astronomers show in a new paper ...

Billions of years ago, a star may have passed incredibly close to our Solar System, triggering a series of cosmic events that led to the creation of the moons around the outer planets and the unusual ...

For years, some astronomers have been suggesting that unusual behaviour on the edge of our solar system is best explained by another, undiscovered planet. That helps explain the orbits of objects ...
