Identified only as a “chunk of crystallized carbon” by its discoverers at the Harvard-Smithsonian Center for Astrophysics, in 1992, Lucy was later observed to have a pulsating aura as a result of its core temperature dropping below 12,000 degrees Fahrenheit (6,600 Celsius). Scientists went on to study the star’s frequency spectrum to determine its composition, using an emerging science called asteroseismology. They used radio waves to understand that the star’s core was turning into diamonds, in a process similar to how geologists study the interior of the earth during earthquakes and other such natural phenomena.
