New research suggests that a massive, unidentified object might have passed through our Solar System billions of years ago, ...

New research using detailed atmospheric models shows Jupiter contains excess oxygen, helping explain its origins and deep atmospheric dynamics ...

In a new study, scientists used advanced computer models to peer beneath Jupiter's dense swirling cloud tops and tackle a ...

Billions of years ago, while the solar system was still young, a massive object may have drifted into it. It's not a spaceship, but it is an alien visitor in its own right—a colossal interstellar body ...

The universe is always moving. While we've found evidence of rogue black holes and planets, new research suggests that a passing star could be out there somewhere. Unfortunately, If it were to swing ...

A passing star, or a stellar flyby, with the potential to pull Neptune out of its orbit by just 0.1%, could mean catastrophe for the entire solar system. But don’t worry — it won’t happen in our ...

In late 2017, a mysterious object tore through our solar system at breakneck speed. Astronomers scrambled to observe the fast moving body using the world’s most powerful telescopes. It was found to be ...

For the first time in years, astronomers are seriously talking about adding a new member to the solar system’s planetary family. I’m not talking about reviving Pluto’s status, but about a potential ...

Researchers have found a candidate for the hypothetical Planet Nine, which could be an undiscovered giant planet way out in our solar system. However, as with all ninth planet research, the new ...

Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its planets looked ...

Jupiter, the largest planet in the solar system, may have been responsible for a mysterious age gap in the early solar system's planet building blocks. Credit: NASA / JPL-Caltech / SwRI / MSSS / Tanya ...

If you were to perfectly follow the steps in An Idiot's Guide to Making a Solar System, you should eventually find yourself with a star surrounded by a flat disc of planetary material orbiting in ...
