Lyra, the lyre is one of the ancient musical instruments. The constellation is positioned at the West Side of summer's Milky Way around the zenith,
and formed with tiny triangle and parallelogram. This constellation is in the shape of lyre of Orpheus given by his father, Apollo. The constellation is small and faint, but it's home to the fifth brightest star of Vega with a magnitude of 0, emitting a pure white light. Vega has a mean of "The Falling Eagle", and represents a jewel of Lyra. The star is also popular in Japan as a heroine of an ancient Chinese legend of "Tanabata". |
