Ancient iron meteorites reveal that some of the Solar System’s first solid bodies were built mostly from tiny heat-forged rock beads called chondrules, while water-rich dust was largely excluded. The ...

If the outer solar system’s first solid bodies had come with a recipe, it would have called for a generous helping of chondrules, millimeter-sized beads of rock forged by heat, and very little icy ...

During the Solar System’s first million years, its earliest outer worlds appear to have formed from a carefully filtered mix ...

What processes are responsible for the first planets in our solar system forming? This is what a recent study published in Nature Astronomy hopes to addres | Space ...

Ancient grains inside one of the oldest known meteorites reveal that a surprisingly strong magnetic field existed during the solar system’s first 200,000 years. The discovery suggests magnetism worked ...

Widespread magnetism dating from our solar system’s earliest beginnings some 4.57 billion years ago likely played a major role in creating orbital order out of chaos. But until now, magnetism’s role ...

When the solar system began building its first solid objects, it had two main ingredients available. One was chondrules—tiny, ...

Iron meteorites show the first bodies of the early solar system were 83% to 92% dry rock, with water arriving millions of ...
