There's No Horizon

A Class 5 example. Despite the Death Star only shooting at minimum power, the superlaser targeting the Holy City of Jedha delivers a huge amount of energy, seeming to have penetrated the moon's crust and created a shockwave in its mantle, as the ground is shown peeling off the surface of the moon (which is what would happen if a planet was hit by a large enough impactor, and presumably a giant death laser as well). The moon probably isn't going to be habitable in the wake of such massive geological devastation.
