Hubble views of the Carousel Lens. Image credit: William Sheu/UCLA =================================================================== Astronomers have found an incredible gravitational lens. Thanks to a chance alignment, a foreground cluster of galaxies has magnified the light of not one, but seven background galaxies, creating a gravitational lens that has been described as “most exquisitely aligned”. It has been dubbed the Carousel Lens. Gravitational lenses are created by the gravity of massive objects, usually galaxies or clusters of galaxies. Their density is such that they warp spacetime, creating a lens that can magnify and change the shape of distant objects. In this case, there are...
