摘要

O RION IS ON E of the brightest and most recognizable constellations. Among its many radiant beacons, none beams as brilliantly as Rigel, the seventh-brightest star in the night sky. Dwelling approximately 850 light-years from Earth, it's the nearest of a class of stars known as blue supergiants. Rigel is about 18 times as massive as our Sun and gives off 100,000 times as much light. Blue supergiants consume their nuclear fuel at a prodigious rate and suffer an astronomically brief life. Although only 0.2% the age of our Sun, Rigel will most likely die within a few million years in a spectacular supernova explosion, shining in our sky as brightly as a quarter Moon.
