Nearby stars trace curved paths bent by the black hole's immense gravity, and a distant spacecraft observes safely from far away while Atlas in an astronaut suit points at the glowing accretion disk.

Lumi floats beside a slowly spinning blue-and-green Earth globe, shining a bright yellow flashlight Sun onto one curved side while the other side rests in soft shadow.
