[00:00:00]Some dead stars may turn into giant crystals. [music] White dwarfs are the dense leftover cores of stars like our sun. As they cool over billions of years, [music] their carbon and oxygen interiors can crystallize, meaning the star's core begins forming a solid lattice. In 2019, astronomers found evidence for this using Gaia data, spotting a delay in how white dwarfs cool that matches the release of heat during crystallization. So, yes, some stellar corpses become planet-sized cosmic crystals.

[00:00:35]Not sparkly in the jewelry sense, more the frozen heart of a dead sun sense.
