[Editor's note: Among the many spectacular observations made with the Hubble Space Telescope, exceptional images of the fascinating processes that occur during the birth and death of stars have been obtained. In the October 1996 issue of The World & I (p. 194), Stephen P. Maran discussed Hubble's images of stellar birth in the article "Windows to Star Birth." Here we present a follow-up piece on the death of stars.]
Some people seem to age faster than others--one old-timer may still be running road races, while his friends born in the same year may already be in nursing homes. In similar fashion, stars age, or "evolve," at different rates. The more massive the star, the faster it burns its nuclear fuel and the more it resembles the proverbial playboy who lit the candle at both ends.
...
. . .
.... The findings suggest how our own Sun may someday meet its fate, and they reveal a better picture of how much more massive stars expire with dramatic flourishes, illuminating and altering the surrounding environment of interstellar space.
