Using an automated supernova-hunting "pipeline," scientists at Lawrence Berkeley National Laboratory (Berkeley Lab) have identified a Type Ia supernova that exploded about four billion years ago. Called iPTF16geu, it's sitting behind a galaxy two billion light years away that is acting like a gigantic gravitational magnifying glass that is splitting the star into four bright images in four different parts of the sky. This is the first such supernova to be seen by gravitational lensing and astronomers believe it could provide us with a better understanding of how the Universe is expanding.
