This Weird Rock Naturally Glows in The Dark, And Now Scientists Have Figured Out How – ScienceAlert

The afterglow of the mineral hackmanite (or tenebrescentsodalite) is a fascinating natural phenomenon that has long been a mystery to scientists even if we’re now able to engineer synthetic materials that glow in the dark more effectively than anything in nature.
Geologists first described the mineral in the 1800s, who were intrigued by its tendency to softly glow a bright pink hue when broken or placed in the dark and lose it in the light. Later research would narrow down the chemistry behind this…
