New studies offer a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs. The findings reveal the distribution of ices in ...

Are planets in the solar system that are closer to the Sun older than the ones further away? – Gavriel, age 10, Paducah, Kentucky A cloud of collapsing gas created our Sun, the first thing to form in ...

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

Astronomers have identified 3I/ATLAS, an ancient, ice-rich interstellar comet potentially older than our solar system.

A new planetary system is forming around the young star HOPS-315. Scientists observed the earliest stages of planet formation around another star. The process involves the cooling and solidifying of ...

The Sun's formation caused temperature differences in the surrounding disk of gas and dust. Inner, hotter regions formed rocky planets from less volatile elements. Outer, colder regions allowed ...

Interstellar comets like 3I/ATLAS could serve as seeds for giant planet formation, potentially explaining how massive planets form around distant stars, according to BBC and Pfalzner’s research.

The comet, officially detected on July 1, 2025, by the ATLAS (Asteroid Terrestrial-impact Last Alert System)telescope in Chile, has been confirmed to be travelling on a hyperbolic trajectory, meaning ...

New research shows how Jupiter carved out rings and gaps that changed how and when planets and meteorites formed.

Jupiter is the fastest spinning planet in our Solar System, completing a rotation in less than 10 hours. This rapid spin ...
