Meteorite impact and the formation of ejecta



In this slow motion meteorite impact we can see the formation of ‘ejecta patterns’ as sub-surface material is blasted from underneath the top layer. These patterns are formed in the creation of impact craters when two celestial bodies collide, typically caused by a meteorite impact on the surface of a planet, mood or asteroid. Impact craters are the dominant geological feature of most moons and asteroids, but are far more rare on Solar System objects with active surface geological processes (such as Earth, Mars, Titan, Europa, and Io), since they are eroded. By studying the size & shape of the crater and resulting ejecta patterns, scientists are able to determine the size, velocity and trajectory of the impactor. Such geological studies not only paint a picture of our solar system’s history, but can also prepare us for impacts in the future…
