The article focuses on the discovery of four images of a single supernova caused by an early-type cluster galaxy gravitational lens. It states that researchers used the Hubble Space Telescope to discover a supernova forming an Einstein cross configuration and mentions the lens also created multiple images of the spiral galaxy the supernova occurred in. It talks about the use of the multiple images to examine the cosmic expansion rate and the distribution of matter in the galaxy lens.
