Image shows a visualisation of the huge, glowing planetary body produced by a planetary collision. In the foreground, fragments of ice and rock fly away from the collision and will later cross in ...

Pluto and Charon formed from a “kiss and capture” collision, a new study from the University of Arizona reveals, rewriting theories of planetary formation. Unlike catastrophic impacts ...

The researchers created the numerical simulations using smoothed particle hydrodynamics software, considered the basis for a wide range of planetary collision studies, to model different scenarios ...
