Distant Supernova, Dark Energy
This image shows the most distant supernova ever detected, over 10 billion light-years away. It was found by subtracting before and after images of a faint galaxy in the Hubble Space Telescope Deep Field. The supernova's measured brightness provides evidence for dark energy, a mysterious force accelerating the expansion of the universe.
