Unlike when a star or planet is the lensing object, black holes warp space-time so much that it noticeably alters the distant star’s apparent location in the sky, as illustrated with the inset. The two images caused by lensing are too close to be spatially resolved, but changing brightness of the two images produce a shift in the position of the source. To illustrate the shift, the inset only shows how the position of the source changes without showing the brightening.
