The Most Extreme Star Ever Found... And It Shouldn_t Exist

Close your eyes and drift into the cosmos, where an ancient star named SDSS J102915+172927—known as Caffau's Star—defies our fundamental understanding of astrophysics.

Let the peaceful wonder of this cosmic anomaly quiet your mind and carry you into a deep, soothing sleep.
