In recent days on La Réunion Island a meeting was held to celebrate the 30th anniversary of the sighting of the supernova 1987A (SN 1987A), the brightest of the last four centuries and for this reason a historic event for modern astronomy. For these celebrations scientists from the Hubble and Chandra space telescopes chose an animation derived from the model of a team of astrophysicists from INAF-Osservatorio Astronomico di Palermo, Italy led by Salvatore Orlando.
