    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.

    Intro and Visual description

    The Ethiopian king, Cepheus (SEE-fee-us), is a circumpolar constellation that sits atop the Milky Way on a throne near his queen Cassiopeia. The legs and seat of his throne make a rough square on the Ursa Major side of Cassiopeia. Cepheus looks like a house (or throne) sitting on the Milky Way. The back of the seat comes to a point at the top above his head.

    Intro and Visual description

    Find the bowl of the big dipper and locate the two stars nearest the handle. A line running through these stars, tracing away from it above the open bowl. This line runs to Deneb, the tail of the constellation Cygnus the Swan. With wings abreast, and long neck outstretched, Cygnus flies along the milky river.

  • Lyr - Lyra the Harp

    IAU Constellation

    Intro and Visual description

    To find Lyra, look for Vega, which forms the brightest point of the Summer Triangle. The summer triangle consists of Deneb in Cygnus the Swan, Altair in Aquila the Eagle, and bluish Vega in Lyra the Harp. Vega soars almost directly overhead in summer, while the bright stars of winter nights are hidden almost directly beneath our feet. Look for a small parallelogram of stars near Vega which forms the frame of the harp.

    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.
