The most luminous supernova revised

supernova_revised

Last June astronomers detected the brightest supernova that has ever been observed, known as ASASSN-15lh. The object had been classified as hydrogen-poor superluminous supernova fuelled by a magnetar, altough it is hotter and more luminous than any other hydrogen–poor supernova thus making the classification uncertain. Now scientists try to uncover the nature of this mysterious source using new observational data.
