How ‘Gravitational Lensing’ Made One Supernova into Four—‘Einstein Cross’

Nicknamed the “Einstein Cross” after the famous physicist who predicted the possibility of the phenomenon as a result of his theory of relativity more than a century ago, the formation was made possible by a strange occurrence known as gravitational lensing.
