1. A Star Made of Diamond
Imagine a star that’s literally a giant diamond floating in space. Astronomers discovered BPM 37093, affectionately called “Lucy,” a crystallized white dwarf whose core is almost entirely diamond. Located about 50 light-years away in the constellation Centaurus, Lucy weighs an astonishing 10 billion trillion trillion carats. This cosmic gem is a stunning example of how stars can end their lives in truly exotic ways.
