Researchers have discovered that a two-step formation process of the early Solar System can explain the chronology and split in volatile and isotope content of the inner and outer Solar System.

Arrokoth is a planetesimal in the Kuiper Belt, a vast stretch of space beyond Neptune that holds remnant building blocks of the solar system leftover from our cosmic neighborhood's formation.

A new theory of the solar system's formation provides an alternative to the idea our system formed from a supernova.

The formation of the solar system is a challenging puzzle for modern astronomy and a terrific tale of extreme forces operating over immense timescales. Let's dig in.

The solar system features a unique dichotomy of planets -- the inner solar system features smaller, drier bodies, while the planets found in the outer solar system are larger and wetter.

Since astronomers discovered the first planets outside our solar system a few decades ago, it’s been clear that other solar systems don’t look much like ours.

A new understanding of exoplanets and their stars is rewriting the recipes for planet formation.

Origins of the Solar System The shock wave from a supernova may have triggered the formation of our sun and planets five billion years ago.

International astronomers have for the first time witnessed the birth of a planetary system beyond Earth's sun that could one day resemble our own.
