Over the past three decades, computer models of planetary system formation have gone from fairly crude representations to ...

Might the first moments of planet formation be more understandable than ever before? Fresh observations suggest that the creation of worlds such as our own is perhaps happening right in front of us, ...

A Moon impact 3.5 billion years ago may have uncovered a forgotten chapter of Solar System history. Tiny crystal grains trapped inside a lunar meteorite are helping scientists understand a violent era ...

Planets are bodies that orbit a star and have sufficient gravitational mass that they form themselves into roughly spherical shapes that, in turn, exert gravitational force on smaller objects around ...
