 If you recall, Type 1A Supernova represent one of our most important standard candles because they are so bright, we can see them from very far away. In 2013, Hubble broke the record in the quest to find the furthest Type 1A with the discovery of SN UDS-10WIL, a supernova that exploded more than 10 billion years ago. At a time when the universe was in its early formative years and stars were being born at a rapid rate. The image at the far left shows the host galaxy without the supernova. The middle image, taken a year later, reveals the galaxy with the supernova. The supernova cannot be seen because it is too close to the center of the host galaxy. To detect the supernova, astronomers subtract the first image from the middle image to see the light from the supernova alone, shown in the image at the far right.
