Hubble Science: Einstein Rings, Optical Illusions
An Einstein Ring can be explained by a phenomenon called gravitational lensing, which causes light shining from a faraway galaxy to be warped by the gravity of an object between its source and the observer. This effect was first theorized by Albert Einstein in 1912, and later worked into his theory of general relativity.
In this video, Dr. Brian Welch explains this fascinating phenomenon of nature, and goes over how important Hubble is to exploring the mysteries of the universe.
