A NASA and Durham University supercomputer simulation suggesting the Moon may have formed within hours of a giant impact between Earth and a Mars-sized body. It is one of the highest-resolution giant-impact simulations run.
HN commenters link it as a cool visualization whenever Theia and Moon formation come up.

If you haven't seen it yet, the simulation released last year of the hypothesized Earth-Theia moon formation is really cool: ▶ this video
It's not my area, but this video looks interesting and is produced by NASA " New Supercomputer Simulation Sheds Light on Moon’s Origin " (October 2022) ▶ this video
What I want to see is the Theia collision rendered in realistic 3D (and if there was enough gas around for sound to carry, that too!) link I guess this is close but not like the Hollywood blockbuster it should be ▶ this video link
How does this finding compare with those from this simulated video of the moon forming? "Collision May Have Formed the Moon in Mere Hours, Simulations Reveal" link ▶ this video And this, from the moon: "Scientists discover huge, heat-emitting blob on the far side of the moon" (2023) link "Remote detection of a lunar granitic batholith at Compton–Belkovich" [from a dormant volcano] (2023) link
The simulation gives some insight, the debris was fed back by gravity in a swirl ▶ this video And always a great PBS Space Time on the subject link
