Phoenix is a constellation in the southern sky that stretches from
roughly −39° to −57° declination, and from 23.5h to 2.5h of right
ascension. Named after the mythical phoenix, it was first depicted on a
celestial atlas by Johann Bayer in his 1603 Uranometria. The French
explorer and astronomer Nicolas Louis de Lacaille charted the brighter
stars and gave their Bayer designations in 1756. The brightest star,
Alpha Phoenicis, or Ankaa, is an orange giant of apparent magnitude 2.4.
Nu Phoenicis has a dust disk, while the constellation boasts ten star
systems with known planets, and HE0107-5240, possibly one of the oldest
stars yet discovered. It has around 1/200,000 the metallicity that the
Sun has and hence must have formed very early in the history of the
universe. The recently discovered galaxy clusters El Gordo and the
Phoenix Cluster—located 7.2 and 5.7 billion light years away
respectively, are two of the largest objects in the visible universe.
Phoenix is the radiant of two annual meteor showers: the Phoenicids in
December, and the July Phoenicids.

Wikiquote quote of the day:
A legend is sung of when England was young, And Knights were
brave and bold. The good King had died, and no one could decide Who was
rightful heir to the Throne. It seemed that the land would be torn by
war, Or saved by a miracle alone — And that miracle appeared in London
town: The Sword in the Stone.
