A new climate modeling study published in the journal Science Advances by researchers from the IBS Center for Climate Physics ...

An object eight times the mass of Jupiter may have swooped around the sun, coming superclose to Mars' present-day orbit ...

Our Solar System is a carefully balanced celestial dance held together by a virtually perfect balance of gravity and inertia.

After running each scenario, the simulation would yield theoretical orbits for the four giant planets that should result from the encounter with that object. Most of the simulations created ...
