These images show type Ia supernova PTF 11kly, the youngest ever detected—over the past three nights. The left image taken August 22 shows the event before it exploded supernova, approximately 1 million times fainter than the human eye can detect. The center image taken August 23 shows the supernova at about 10,000 times fainter than the human eye can detect. The right image taken August 24 shows that the event is 6 times brighter than the previous day. In 2 weeks time it should be visible with a good pair of binoculars.
