Gravitational Lens Shows a Supernova Four Times | Space Video
Показать описание
Seen by the Hubble Space Telescope, the huge cluster and one of the galaxies within it are bending the light from a distant supernova and creating four separate images of the supernova.
The light has been magnified and distorted due to gravitational lensing and as a result the images are arranged around the elliptical galaxy in a formation known as an Einstein cross.
