+      **Phoenix** is a minor [constellation](constellation "wikilink") in the
+      [southern sky](southern_sky "wikilink"). Named after the mythical
+      [phoenix](Phoenix_(mythology) "wikilink"), it was first depicted on a
+      celestial atlas by [Johann Bayer](Johann_Bayer "wikilink") in his 1603
+      *[Uranometria](Uranometria "wikilink")*. The French explorer and
+      astronomer [Nicolas Louis de
+      Lacaille](Nicolas_Louis_de_Lacaille "wikilink") charted the brighter
+      stars and gave their [Bayer designations](Bayer_designation "wikilink")
+      in 1756. The constellation stretches from roughly −39 degrees to −57 degrees
+      [declination](declination "wikilink"), and from 23.5h to 2.5h of [right
+      ascension](right_ascension "wikilink"). The constellations Phoenix,
+      [Grus](Grus_(constellation) "wikilink"),
+      [Pavo](Pavo_(constellation) "wikilink") and [Tucana](Tucana "wikilink"),
+      are known as the Southern Birds.

+      - question: |
+          Who charted the Phoenix constellation?
+        answer: |
+          The Phoenix constellation was charted by french explorer and
+          astronomer Nicolas Louis de Lacaille.
+      - question: |
+          How far does the Phoenix constellation stretch?
+        answer: |
+          The phoenix constellation stretches from roughly −39° to −57°
+          declination, and from 23.5h to 2.5h of right ascension.
+  - context: |
+      Phoenix was the largest of the 12 constellations established by [Petrus
+      Plancius](Petrus_Plancius "wikilink") from the observations of [Pieter
+      Dirkszoon Keyser](Pieter_Dirkszoon_Keyser "wikilink") and [Frederick de
+      Houtman](Frederick_de_Houtman "wikilink"). It first appeared on a 35cm
+      diameter celestial globe published in 1597 (or 1598) in Amsterdam by
+      Plancius with [Jodocus Hondius](Jodocus_Hondius "wikilink"). The first
+      depiction of this constellation in a celestial atlas was in [Johann
+      Bayer](Johann_Bayer "wikilink")'s
+      *[Uranometria](Uranometria "wikilink")* of 1603. De Houtman included
+      it in his southern star catalog the same year under the Dutch name *Den
+      voghel Fenicx*, "The Bird Phoenix", symbolising the
+      [phoenix](Phoenix_(mythology) "wikilink") of classical mythology. One
+      name of the brightest star [Alpha
+      Phoenicis](Alpha_Phoenicis "wikilink")—Ankaa—is derived from the Arabic:
+      العنقاء, romanized: al-‘anqā’, lit. 'the phoenix', and
+      was coined sometime after 1800 in relation to the constellation.
+    questions_and_answers:
+      - question: |
+          What is the brightest star in the Phoenix constellation
+          called?
+        answer: |
+          Alpha Phoenicis or Ankaa is the brightest star in the Phoenix
+          Constellation.
+      - question: Where did the Phoenix constellation first appear?
+        answer: |
+          The Phoenix constellation first appeared on a 35-cm diameter
+          celestial globe published in 1597 (or 1598) in Amsterdam by
+          Plancius with Jodocus Hondius.
+      - question: |
+          What does "The Bird Phoenix" symbolize?
+        answer: |
+          "The Bird Phoenix" symbolizes the phoenix of classical mythology.
+  - context: |
+      Phoenix is a small constellation bordered by [Fornax](Fornax "wikilink")
+      and Sculptor to the north, Grus to the west, Tucana to the south,
+      touching on the corner of [Hydrus](Hydrus "wikilink") to the south, and
+      [Eridanus](Eridanus_(constellation) "wikilink") to the east and
+      southeast. The bright star [Achernar](Achernar "wikilink") is
+      nearby. The three-letter abbreviation for the constellation, as
+      adopted by the [International Astronomical
+      Union](International_Astronomical_Union "wikilink") in 1922, is
+      "Phe". The official constellation boundaries, as set by Belgian
+      astronomer [Eugène Delporte](Eugène_Joseph_Delporte "wikilink") in 1930,
+      are defined by a polygon of 10 segments. In the [equatorial coordinate
+      system](equatorial_coordinate_system "wikilink"), the [right
+      ascension](right_ascension "wikilink") coordinates of these borders lie
+      between 23<sup>h</sup> 26.5<sup>m</sup> and 02<sup>h</sup> 25.0<sup>m</sup>,
+      while the [declination](declination "wikilink")
+      coordinates are between −39.31° and −57.84°. This means it remains
+      below the horizon to anyone living north of the [40th
+      parallel](40th_parallel_north "wikilink") in the [Northern
+      Hemisphere](Northern_Hemisphere "wikilink"), and remains low in the sky
+      for anyone living north of the [equator](equator "wikilink"). It is most
+      visible from locations such as Australia and South Africa during late
+      [Southern Hemisphere](Southern_Hemisphere "wikilink") spring. Most
+      of the constellation lies within, and can be located by, forming a
+      triangle of the bright stars Achernar, [Fomalhaut](Fomalhaut "wikilink")
+      and [Beta Ceti](Beta_Ceti "wikilink")—Ankaa lies roughly in the centre
+      of this.
+    questions_and_answers:
+      - question: What are the characteristics of the Phoenix constellation?
+        answer: |
+          Phoenix is a small constellation bordered by Fornax and Sculptor to
+          the north, Grus to the west, Tucana to the south, touching on the
+          corner of Hydrus to the south, and Eridanus to the east and southeast.
+          The bright star Achernar is nearby.
+      - question: |
+          When is the phoenix constellation most visible?
+        answer: |
+          Phoenix is most visible from locations such as Australia and
+          South Africa during late Southern Hemisphere spring.
+      - question: |
+          What are the Phoenix Constellation boundaries?
+        answer: |
+          The official constellation boundaries for Phoenix, as set by Belgian
+          astronomer Eugène Delporte in 1930, are defined by a polygon of 10
+          segments.
+  - context: |
+      Ten stars have been found to have planets to date, and four planetary
+      systems have been discovered with the [SuperWASP](SuperWASP "wikilink")
+      project. [HD 142](HD_142 "wikilink") is a yellow giant that has an
+      apparent magnitude of 5.7, and has a planet ([HD 142b](HD_142_b
+      "wikilink")) 1.36 times the mass of Jupiter which orbits every 328 days.
+      [HD 2039](HD_2039 "wikilink") is a yellow subgiant with an apparent
+      magnitude of 9.0 around 330 light years away which has a planet ([HD 2039
+      b](HD_2039_b "wikilink")) six times the mass of Jupiter. [WASP-18](WASP-18
+      "wikilink") is a star of magnitude 9.29 which was discovered to have a hot
+      Jupiter-like planet ([WASP-18b](WASP-18b "wikilink")) taking less than a
+      day to orbit the star. The planet is suspected to be causing WASP-18 to
+      appear older than it really is. [WASP-4](WASP-4 "wikilink") and
+      [WASP-5](WASP-5 "wikilink") are solar-type yellow stars around 1000
+      light years distant and of 13th magnitude, each with a single planet
+      larger than Jupiter. [WASP-29](WASP-29 "wikilink") is an orange
+      dwarf of spectral type K4V and visual magnitude 11.3, which has a
+      planetary companion of similar size and mass to Saturn. The planet
+      completes an orbit every 3.9 days.
+    questions_and_answers:
+      - question: In the Phoenix constellation, how many stars have planets?
+        answer: |
+          In the Phoenix constellation, ten stars have been found to have
+          planets to date, and four planetary systems have been discovered
+          with the SuperWASP project.
+      - question: What is HD 142?
+        answer: |
+          HD 142 is a yellow giant that has an apparent magnitude of 5.7, and
+          has a planet (HD 142 b) 1.36 times the mass of Jupiter which
+          orbits every 328 days.
+      - question: |
+          Are WASP-4 and WASP-5 solar-type yellow stars?
+        answer: |
+          Yes, WASP-4 and WASP-5 are solar-type yellow stars around 1000 light
+          years distant and of 13th magnitude, each with a single planet
+          larger than Jupiter.
+  - context: |
+      The constellation does not lie on the
+      [galactic plane](galactic_plane "wikilink") of the Milky Way, and there
+      are no prominent star clusters. [NGC 625](NGC_625 "wikilink") is a dwarf
+      [irregular galaxy](irregular_galaxy "wikilink") of apparent magnitude 11.0
+      and lying some 12.7 million light years distant. Only 24000 light years in
+      diameter, it is an outlying member of the [Sculptor Group](Sculptor_Group
+      "wikilink"). NGC 625 is thought to have been involved in a collision and
+      is experiencing a burst of [active star formation](Active_galactic_nucleus
+      "wikilink"). [NGC 37](NGC_37 "wikilink") is a
+      [lenticular galaxy](lenticular_galaxy "wikilink") of apparent magnitude
+      14.66. It is approximately 42 [kiloparsecs](kiloparsecs "wikilink")
+      (137,000 [light-years](light-years "wikilink")) in diameter and about
+      12.9 billion years old. [Robert's Quartet](Robert's_Quartet "wikilink")
+      (composed of the irregular galaxy [NGC 87](NGC_87 "wikilink"), and three
+      spiral galaxies [NGC 88](NGC_88 "wikilink"), [NGC 89](NGC_89 "wikilink")
+      and [NGC 92](NGC_92 "wikilink")) is a group of four galaxies located
+      around 160 million light-years away which are in the process of colliding
+      and merging. They are within a circle of radius of 1.6 arcmin,
+      corresponding to about 75,000 light-years. Located in the galaxy ESO
+      243-49 is [HLX-1](HLX-1 "wikilink"), an
+      [intermediate-mass black hole](intermediate-mass_black_hole
+      "wikilink")—the first one of its kind identified. It is thought to be a
+      remnant of a dwarf galaxy that was absorbed in a
+      [collision](Interacting_galaxy "wikilink") with ESO 243-49. Before its
+      discovery, this class of black hole was only hypothesized.
