In this Hubble image, the disk of the jellyfish galaxy JO206 is trailed by long tendrils of bright star formation that stretch towards the bottom right of the image, just as jellyfish trail tentacles behind them. The color image was made from separate exposures taken in the visible, ultraviolet and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). The image is based on data obtained through six filters. The color results from assigning different hues to each monochromatic image associated with an individual filter.

The enlarged inset view reveals four images of SN Refsdal, spotted in 2014, arranged around a giant elliptical galaxy within the cluster. The light from the supernova passes so closely to the galaxy’s dense core that several light paths are redirected and focused toward Earth. The result is that astronomers see four images that form an Einstein Cross. The blue streaks wrapping around the galaxy are the stretched images of SN Refsdal’s parent spiral galaxy, which has been distorted by the warping of space. Computer models of the cluster predict that another image of the stellar blast will appear within 5 years. The red circle marks the possible location of the next supernova image. Astronomers may have missed an earlier appearance of the supernova in 1995, as marked by the blue circle. These multiple appearances of the exploding star are due to the various paths its light is taking through the maze of clumpy dark matter in the galactic grouping. Each image takes a different route through the cluster and arrives at a different time, due, in part, to differences in the length of the pathways the light follows to reach Earth.
