The Lyra Constellation

The Lyra Constellation

Lyra (Latin for 'lyre', from Ancient Greek: λύρα) is a small constellation. It is one of the 48 listed by the 2nd century astronomer Ptolemy. This is one of the modern 88 constellations recognized by the International Astronomical Union (IAU). 

Note: The lyre is a stringed musical instrument that originated in ancient Greece. It typically features a yoke with two arms and a crossbar, with strings running from a tailpiece to the crossbar, and is primarily played by plucking the strings.

Lyra was often represented on star maps as a vulture or an eagle carrying a lyre, and hence is sometimes referred to as Vultur Cadens or Aquila Cadens ("Falling Vulture" or "Falling Eagle"), respectively. 

Beginning at the north, Lyra is bordered by Draco, Hercules, Vulpecula, and Cygnus. Lyra is nearly overhead in temperate northern latitudes shortly after midnight at the start of summer. From the equator to about the 40th parallel south it is visible low in the northern sky during the same (thus winter) months.

Vega, Lyra's brightest star, is one of the brightest stars in the night sky, and forms a corner of the famed Summer Triangle asterism. Beta Lyrae is the prototype of a class of binary stars known as Beta Lyrae variables. These binary stars are so close to each other that they become egg-shaped and material flows from one to the other. Epsilon Lyrae, known informally as the Double Double, is a complex multiple star system. Lyra also hosts the Ring Nebula, the second-discovered and best-known planetary nebula.
