German scientists have discovered text that was written by Ibn Sina (he was a famous Persian philosopher). This new text shares the 11th Century scholar’s sighting of a supernova back in 1006 AD. The year was 397 according to the Islamic Hijri calendar when Ibn Sina (called Avicenna in Latin) describes witnessing the event right before his eyes.
Ibn Sina was a Persian physician as well as a philosopher who is to this day named the most influential medieval Islamic philosopher/scientist in the world. Scientists who studied the writings estimate the text was written when Ibn Sina was in Turkmenistan, Uzbekistan or present day Iran. It is most likely that he was located in Uzbekistan.
Upon translation, researchers found Ibn Sina writing about tailless objects, setting it apart from other common objects found in the sky. He says the new star was becoming dimmer and dimmer until it completely disappeared. At first, Ibn Sina writes, it was a dark and green color and then sparks were thrown and the color white filled the space.
