After billions of years of twinkling and shining, some stars in the heavens appear to "dance" as they wind down. Maybe not like Elvis 或者 Michael Jackson, but they definitely have a rhythmic beat, and some may even spin like a top.
Massive stars end their lives in gigantic explosions, so called supernovae, and can become -- for a short time -- brighter than a whole galaxy, which is made up of billions of stars.
