"A crystal the size of our Moon has been revealed hidden at the centre of a dying star, after an analysis of pulsations in the star's brightness.
The measurement confirms indirect evidence that the cores of all such dying stars - called white dwarfs - solidify as they cool. The discovery may improve age estimates of our galaxy, of which white dwarfs provide an important constraint.
Astronomers led by Travis Metcalfe of the Harvard-Smithsonian Center for Astrophysics in Cambridge, Massachusetts, US, studied the white dwarf BPM 37093, the only known pulsating white dwarf in our galaxy thought likely to have produced a crystal core."
I think like I'm hearing now the song of Blondie
