An article to be published in the journal “Monthly Notices of the Royal Astronomical Society” describes the study of the supernova ASASSN-15no. A team of astronomers, especially from the National Institute of Astrophysics in Padua, Italy, led by Stefano Benetti used a number of telescopes to observe an explosion that was initially hidden by a thick layer of gas and dust ejected by the progenitor star a few years before. For this reason, the astronomers have called it a supernova that plays hide and seek but in the end it popped out and was at least ten times brighter than normal.
