article_snippet: Both the galaxy and the galaxy cluster are acting like a giant cosmic lens, bending and magnifying light from the supernova behind them .
article_snippet: the galaxy cluster's gravity causes passing photons, or particles of light, to bend.
article_snippet: Gravitational lensing occurs when galaxies and other objects amplify Light from the supernova coming from other distant objects.
article_snippet: the intervening galaxy cluster focuses the supernova light along at least three separate paths, and then when one of those light paths happens to be precisely aligned with a single elliptical galaxy within the cluster, a secondary lensing effect occurs.
article_snippet: The dark matter associated with the elliptical galaxy refocuses the supernova light into four more paths .
highlights_snippet: A massive galaxy cluster warped its light as its light travelled to Earth .
