Virgo
Virgo (the virgin) is a constellation of the zodiac. Lying between Leo to the west and the Libra to the east, it is one of the largest constellations in the sky. It can be easily found through its bright α star, Spica.
Notable features
The most prominent star in Virgo is Spica (α Vir), which represents an ear of wheat in the goddess's hand. Spica makes it easy to locate Virgo, as it can be found by following the curve of the Big Dipper to Arcturus in Boötes and continuing from there in the same curve ("follow the arc to Arcturus and speed on to Spica").
Other bright stars in Virgo include Zavijah (β Vir), Porrima (γ Vir), Auva (δ Vir) and Vindemiatrix (ε Vir). Other fainter stars which were also given a name are Heze (ζ Vir), Zaniah (η Vir), Syrma (ι Vir) and Rijl al Awwa (μ Vir).
The star 70 Virginis is an extrasolar planetary system with one confirmed planet 6.6 times the mass of Jupiter.
Notable deep sky objects
Because of the presence of a galaxy cluster (consequently called the Virgo cluster) within its borders 5° to 10° west of Vindemiatrix (ε Vir), this constellation is especially rich in galaxies.
Some examples are M49 (elliptical), M58 (spiral), M59 (elliptical), M60 (elliptical), M61 (spiral), M84 (elliptical), M86 (elliptical), M87 (elliptical and a famous radiosource), and M90 (spiral). A noted galaxy that is not part of the cluster is M104, an elliptical galaxy also called the Sombrero Galaxy. It is located about 10° due west of Spica.
Mythology
Who exactly Virgo is supposed to represent is uncertain; in history, it has been associated with nearly every prominent goddess, including Ishtar, Isis, Demeter, Cybele, Athena, and so forth.
According to one version, the constellation depicts Astraea, the virgin daughter of the god Zeus and the goddess Themis. Astraea was known as the goddess of justice, hence the scales of justice Libra nearby, and supposedly ruled the world at one point with her wise ways until mankind became so callous that she returned to skies in disgust. Persephone is often mentioned as well, Virgo being visible mainly in the spring months when she was believed to have risen from the underworld.
Astrology
The astrological sign Virgo (August 23 - September 22) is associated with the constellation. In some cosmologies, Virgo is associated with the classical element Earth, and thus called an Earth Sign (with Taurus and Capricorn).
Its polar opposite is Pisces.
