A Galaxy Bent Light Into a Perfect Ring

When a foreground galaxy aligns with a more distant source, gravity bends the background light into an Einstein ring. The ring is not a physical structure: it is a distorted image made by curved spacetime. Editorial note: a near-perfect ring requires an unusually precise alignment, which is why most gravitational lenses appear as arcs or multiple images instead.
