• Aql - Aquila the Eagle

    IAU Constellation

    Size

    22 of 88

    Astronomical Regions

    Intro and Visual description

    Between Cygnus and Sagittarius, with Altair (its brightest star) making the south end of the Summer Triangle (along with Deneb of Cygnus and Vega of Lyra). As the night sky changes, Aquila the Eagle and Cygnus the Swan swing slowly westward across the sky towards the horizon. The Eagle sets tail first, followed closely by the Swan, who dives beak first below the western horizon.

  • Peg - Pegasus the Flying Horse

    Size

    Astronomical Regions

    Intro and Visual description

    Farther along on the line from the Pointers to Polaris and Cassiopeia is a large, nearly perfect square of four stars. This is the Great Square of Pegasus. Pegasus, the Winged Horse, lies almost directly overhead in autumn. Located east of Andromeda; signals the coming of Fall. Because Pegasus flies so fast, his hind quarters can’t be seen.

  • Psc - Pisces the Fishes

    IAU Constellation

    Size

    14 of 88

    Astronomical Regions

    Intro and Visual description

    South of Pegasus and Andromeda, near Aquarius. Pisces represents two fish tied together by two cords:

    • The western fish, a pentagon of stars just south of Pegasus, is an asterism known as the circlet.
    • The other fish lies on the opposite side of Pegasus, just under Andromeda.

    The brightest star, alpha-Piscium, is known as El-Rischa or the "knot" because it ties the two cords together with the two fish on the opposite ends. Alpha-Piscium lies nestled up next to Mira, a bright variable star of the constellation Cetus the Whale.

  • PsA - Piscis Austrinus the Southern Fish

    Size

    60 of 88

    Astronomical Regions

    Intro and Visual description

    Unlike Pisces, the zodiac constellation which consists of two fish held together by a string, Piscis Austrinus is a single fish. Piscis Austrinus is a very faint constellation located south of Aquarius, and is often depicted as drinking from Aquarius’ water jar (but why would a fish want to drink water??). Except for the bright star Formalhaut, Piscis Austrinus is rather unremarkable.

  • Scl - Sculptor the Sculptor's Workshop

    Size

    36 of 88

    Astronomical Regions

    Intro and Visual description

    Located south of the flukes of Cetus the Whale. Trace to it by following a line southward from Alpheratz (the corner of Pegasus and Andromeda) through gamma-Pegasi, across Pisces and Cetus. This line will run through Beta-Ceti (Diphda) just before reaching the faint stars of Sculptor (alpha-Sculptoris is only magnitude 4.3). Look for it from northern latitudes barely visible low in the south during September and October.
