Simpson and Chen ran mathematical models looking at how differently sized Earth-like worlds would have affected the rest of ...

This finding explains the discrepancy between the number of basins detected on the Moon (~40) and the number predicted (~300) by an accretion scenario of planet formation.

A super-Earth planet that dips in and out of its star's habitable zone has been discovered just 19.7 light-years away.

While the composition of gas and dust in a molecular cloud is fairly uniform, everything changes once a star begins to form.
