An article published in “The Astrophysical Journal” reports a study on the supernova SN 2016iet. A team of researchers used a number of telescopes to collect data on it. Almost three years of study have followed its first sighting, which happened on November 14, 2016, leading to estimate that the progenitor star had a mass about 200 times the Sun’s which exploded in what appears to be the first strong case of pair-instability supernova, which ends with the star’s total destruction.
