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 ...

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 ...

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 ...

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 ...

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

When the solar system first took up the task of building solid bodies—such as planets, moons and protoplanets—it basically had a choice between two ingredients: heat-forged chondrules, which were ...

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

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 ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...
