For centuries, astronomers have sought to understand the formation and evolution of the solar system and the dynamics that ...

Researchers Nathan A. Kaib and Sean N. Raymond have evaluated the impact of passing stars on the long-term stability of the ...

New research suggests that our entire solar system is vulnerable to being thrown into chaos by a distant star.

A passing star has been discovered that could cause chaos in the Solar System, sending Earth flying out of orbit.

But this assumes that nothing affects the Solar System in the meantime, and that is not a certainty. As we travel around the ...

For decades it was thought that water was prevalent in the outer reaches of the Solar System early in its history, with ...

Simulations show that the stars’ tug could send Mercury, Venus or Mars crashing into Earth — or let Jupiter eject our world from the solar system.

The small world was found during a search for the hypothetical Planet Nine, and astronomers say the next time it will reach ...

Mercury, for instance, is already the wild card of the inner planets. Its orbit grows more eccentric over time, increasing ...

Astronomers have discovered a massive hydrogen cloud, known as Eos, shining brightly in ultraviolet light near our solar ...

Researchers Nathan A. Kaib and Sean N. Raymond have evaluated how passing stars can affect the long-term stability of the ...

Astronomers spotted water around a young, sun-like star for the first time ever, and it could help us understand solar system formation.
