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.

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, ...
