A team of researchers chose to observe the galaxy cluster PLCK G165.7+67.0, also known as G165, for its high star rate formation that also leads to higher supernova rates. One image, which you can see above, captures what looks to be a streak of light with three distinct dots that appear brighter than the rest of it. As Dr. Brenda Frye from the University of Arizona explained, those dots correspond to an exploding white dwarf star. It is also gravitationally lensed — that is, there's a cluster of galaxies between us and the star that served as a lens, bending the supernova's light into multiple images. Frye likened it to a trifold mirror that shows a different image of the person sitting in front of it. To note, it is the most distant Type Ia supernova, which is a supernova that occurs in a binary system, observed to date.
