Its story

In Cygnus burns a rare blue O-type star, one of the hottest and most massive classes in the stellar catalogue. Its light took roughly 1,942 years to reach us: it set out in the 1st century, when Rome was at its peak under the Flavian emperors and Pompeii had not yet been buried by Vesuvius. That almost violet blue marks the heart of the swan with the fury of cosmic youth.
