Stunning 'Einstein engagement ring' from the early universe is one of the oldest ever discovered

Hubble Space Telescope captured a rare, near-perfect ring of gravitationally warped light, known as an "Einstein ring," shining from a galaxy in the early universe.

Einstein rings occur when light from a distant galaxy is bent around a closer galaxy or black hole that is perfectly aligned between the distant object and the observer.

The Einstein ring is so far away that you might think its light should not be visible to us.
