This is Spica in an HR Diagram. As you can see Spica is located three places from the middle for the brightness and its surface temperature 25,000 fahrenhieght.

Spica’s Constellation and its Story

The Virgo constellation depicts Astraea, the virgin daughter of the god Zeus and the goddess Themis. Astraea was known as the goddess of justice, and was identified as this constellation due to the presence of the sexes of justice (Libra) nearby, and supposedly ruled the world with her wise ways until mankind became so callous that she returned to the skies, disgusted. Virgo is also identified with Persephone, daughter of Demeter (goddess of agriculture and guardian of marriage). Persephone was the goddess of innocence and purity, then later on became the Queen of the Underworld, when she was abruptly snatched away by Hades

Spicas life Cycle

Spica is a star so it was born out of a large molecular cloud (whose density and size permits the formation of molecules)the joined the main sequence, after a short life it leaves the main sequence and it begins to grow in size and brightness, and a short trip back along the horizontal branch will follow before another rise and finally a Supernova leaving behind probably a Black Hole. When it dies it is in aging stage.
