Study confirms that stellar novae are the main source of lithium in the universe

Lithium, the lightest solid element, is created during astrophysical phenomena, but its origin has been elusive. Recently, a group of researchers detected enormous quantities of beryllium-7, an unstable element that decays into lithium in 53.2 days, inside nova Sagittarii 2015 N.2, which suggests that novae are the main source of lithium in the galaxy.
