Most-Luminous Ever Supernova Discovered (IMAGE)
Caption
A team of astronomers, including Carnegie's Benjamin Shappee, Nidia Morrell, and Ian Thompson, has discovered the most-luminous supernova ever observed, called ASAS-SN-15lh. It is two times more luminous than any supernova previously discovered. In fact, ASAS-SN-15lh at peak was almost 50 times more luminous than the entire Milky Way galaxy. This is a comparison between a false-color pre-explosion image from the Dark Energy Survey and false-color follow-up image from the LCOGT 1-m network, courtesy of Benjamin Shappee.
