NASA’s Webb Provides Crash Course on Planet-Shattering Collisions - NASA Science

JWST Teaches Us More About ‘Extreme Debris Disks’ – Young Planetary Systems Where Mars-Sized And Moon-Sized Worlds Collide

Theory says these systems should be more common, but only 1 percent of young stars have them.

NASA’s Webb Provides Crash Course on Planet-Shattering Collisions - NASA Science

In the early history of our solar system, scientists theorize that a Mars-sized object called Theia smashed into the infant Earth, vaporizing massive amounts of rock and blasting it into space. Some of that material coalesced into the Moon, where NASA’s Artemis program is returning humans, preparing for Mars, and shaping the future of space […]

Webb reveals the telltale dust of giant planetary collisions

A study of 21 dusty star systems reveals how debris composition distinguishes violent impacts between Mars-sized bodies from smaller collisions involving Moon-sized objects.
