In this image, the proposed hit-and-run collision is simulated in 3D, shown about an hour after impact. A cut-away view shows the iron cores. Theia (or most of it) barely escapes, so a follow-on ...

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 ...

For nearly 40 years, scientists have generally agreed that Earth's Moon formed from debris after a massive collision with our ...

This video simulates what astronomers, studying Hubble Space Telescope observations, consider evidence for the first-ever detection of the aftermath of a titanic planetary collision in another ...

An asteroid the size of the Empire State Building, named Apophis, could potentially hit Earth in 2029, but scientists ...

We learn how Lux Aeterna made the stunning VFX for Our Universe, Secrets of the Neanderthals and Solar System.

In the final phase of terrestrial planet formation, planetary embryos and planetesimals ... we use our recently developed GPU N-body code GANBISS. GANBISS treats all collision as perfect merging and ...

Something catastrophic like an interplanetary collision, perhaps. This catastrophic clashing theory has been in the works for a while now, and planetary scientists think that Mercury might have ...
