Our solar system may not be as isolated as we once thought. According to a new study, more than 1 million interstellar objects could be lurking in the outer reaches of our cosmic neighborhood, quietly ...

The moment an object from another star system appears in survey data, astronomy shifts into sprint mode. Interstellar visitors do not linger, and each one offers a narrow window to study material ...

Milky Way billions of years ago. This remarkable journey, revealed through the most detailed catalog of similar stars to date, transforms our understanding of the solar system’s origins. Published in ...

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 ...

Samples from Ryugu, a small, near-Earth asteroid, preserve natural remanent magnetization (NRM) from the early history of the solar system. However, despite multiple studies, there is currently no ...

A small, round piece of asteroid Ryugu (sample #91), called “S-lunar,” contains tiny particles (less than 1 mm) that will allow planetary scientists to study the magnetic signature of the early solar ...

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 ...

To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread ...
