Heinrich Olbers, famous for his paradox about the night sky, viewed the massive star during the first half of the 19th century, as did Nicolas Flammarion, the great French popularizer of astronomy.
Because there have been very few massive stars that have been observed really well, we never realized how fast they could evolve - until we saw one doing it and then checked it against the theory," de Groot says.
Theory predicts that a star as massive and as old as P Cygni should have cooled half as slowly - and thus brightened somewhat less - over the past 300 years, de Groot notes.
