A black hole’s gravity bends light rays from a star far behind it, so that the star not only seems to brighten, but also seems to be in a different place. The star (yellow circle, middle left) sends light (solid yellow line) toward the black hole (black dot), which bends the light so that observers on Earth (blue circle) see the star appear elsewhere (yellow circle, lower left).
