188-moon-forming-impact-v2-dixon – A catastrophic cosmic collision depicts the Giant Impact Hypothesis, in which a Mars-sized protoplanet (Theia) strikes the proto-Earth. The violent grazing impact generates a brilliant explosion of incandescent magma, vaporized rock, and glowing debris, breaching the planet's crust. The resulting debris disc coalesces in about a month to form Earth's Moon. hybrid digital and traditional art, 1994/2022 © Don Dixon
