(MEDIA GENERAL) — Astronomers with the Hubble Space Telescope describe the find of a distant exploding star in four images like finding a four-leaf clover. It’s something very rare and special.
The images are arranged in a cross-shaped pattern by the powerful gravity of a galaxy in the foreground that’s embedded in a huge cluster of galaxies. According to Hubble astronomers, the arrangement forms a cross-shaped pattern called an Einstein Cross.
The galaxy cluster and the galaxy in the foreground are five billion light-years away from Earth. The supernova behind it is 9.3 billion light-years away.
