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 ...

A planet so distant that its starlight began traveling toward Earth around the Middle Ages has given one University of Cincinnati graduate student the kind of first look astronomers wait years for.

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 ...

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

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 ...
