Its story

Far away, in Chamaeleon, the small southern constellation named by navigators who first crossed the southern seas, beats a blue B-type star whose brightness wavers slightly, like a flame pushed by the wind. Its light takes nearly 927 years to reach us: what we see today departed around 1099, just as the crusaders were conquering Jerusalem after a two-year siege and a new chapter opened between East and West.
