Knocking over an ice giant —Jacob Kegerreis, Durham University

An SPH simulation of the giant impact of a protoplanet twice the mass of Earth crashing into the young Uranus, thought to explain the planet's unique tilted spin, using an unprecedented 100,000,000 simulation particles - 1000 times more than the current standard - coloured by their thermal energy.
