The detection of the relatively short-lived (~106 yr) radioactive 26Al in our Galaxy, more than 12 years ago, convincingly showed that nucleosynthesis is still active today on a large scale. Still, despite considerable efforts in the past decade, the site of this nucleosynthetic activity cannot be identified from theory alone; several potential sites are still on the list, been able to provide the 2-3 M⊙ of 26Al per Myr, implied by the detected 1.8 MeV flux of ~4 10−4 cm−2 s−1 from the galactic plane (see for a review).
