A gamma-ray signal is the first hard evidence that explosions on white dwarf stars are "lithium factories" A white dwarf is the core of a sun-like star that has reached the end of its life.

Lithium was the heaviest element to be produced in the Big Bang , which also generated hydrogen and helium.

The gamma-ray signal is not particularly strong, meaning that the signal-to-noise ratio is low.

The significance of the detection by INTEGRAL is 2.5 -sigma, meaning there's about a 2.1% chance the signal might not be real.

Astronomers have been searching for this evidence for a long time, and while this detection is not yet confirmed, it gives astronomers confidence.
