The stellar environment of the Solar System at its birth is not yet fully known , as it has accomplished 20 revolutions around the galactic centre since its formation 4.5 billion years ago. Matthieu Gounelle (Laboratoire de Minéralogie et Cosmochimie du Muséum National d'Histoire naturelle/CNRS) and Georges Meynet (Observatoire de Genève) established the Solar System genealogy thanx to a radioactive element, 26Al, which was present in the nascent Solar System. Their results are published this week in the journal Astronomy & Astrophysics. The authors of this paper show that the parent massive star (name proposed: Coatlicue, from the Sun's mother in the Aztec cosmogony) and which is roughly 30 times more massive than our Sun, they was born with roughly 2000 stars. The star Coatlicue died in a supernova explosion. The authors show that the parent massive star, which they propose to call Coatlicue (the Sun's mother in the Aztec cosmogony), and which is ro
