Astronomers have seen the aftermath of two planetary pile-ups in the same turbulent star system — providing potential insights into how planets form 1. Observations from the early 2000s indicated that ...
The giant planets weren't always where we find them today. Jupiter, Saturn, Uranus and Neptune formed in a more compact configuration and later underwent a violent reshuffling that scattered them to ...
Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

New Planet Emerging in Our Solar System
This gas cloud located 500 light years away from our solar system is about to become a planet.This process usually takes a few hundred million years, but what if we made it happen much quicker. And ...
Roughly four and a half billion years ago the planet Theia slammed into Earth, destroying itself, melting large portions of our planet’s mantle and ejecting a huge debris disk that later pulled ...
Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...
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 ...
A new study has proposed the existence of Planet Y, an alternative Planet Nine candidate that is smaller and closer to Earth than the hypothetical Planet X, which astronomers have been hunting for ...
When you see art of our solar system as the planet orbit the sun, you may notice that Earth's orbit has a tilt. It is not a perfect circle. What's more, Earth is not the only planet that displays such ...
LONDON — The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper's authors have ...
