What Is Spica?

Spica is the 16th brightest star in the night sky and sits about 250 light years away. It is the closest binary star system, with two closely positioned stars. Its name gives away its location, as its full title, Spica Virginis, is Latin for “Virgos Ear of Grain.” It represents the ear of corn that the constellation Virgo holds in her right hand. In ancient times, Greek and Roman cultures associated this constellation with the goddess Demeter, who looked over the harvest of grain.

Why Is Spica So Bright?

Spica is bright due to its proximity to the Earth at a distance of only 250 light years. Many other stars are thousands of light years away. Another reason that it is so brilliant is that it is quite large. Also, there are two stars in the system, Spica 1 and Spica 2. Both are significantly larger than our sun and many times as bright. They are also part of spectral class B, giving Spica its blue color. Since the stars are so close, gravity pulls them toward each other, causing them to take on an egg shape. However, we are unable to see the egg shape from Earth.

What Is the Virgo Constellation?

Virgo is the second largest constellation in the night sky, and you can see it in both the northern and southern hemispheres. If you live in the north, you will want to look for it from March to July, while people in the southern hemisphere can see it during the fall and winter months. The story behind the constellation is complex, with many variations, and no one is sure exactly who Virgo represents. One story tells of Dionysus offering wine to Icarius, a winemaker, and local shepherds out of friendship. However, the drunken shepherds thought that they were poisoned and killed Icarius for revenge. Later, his daughter, Erigone, found his body and buried him before hanging herself out of grief. When Dionysus learned what had happened, he was angry and caused a plague to overtake the city of Athens before placing Erigone among the stars as Virgo. He placed Icarius next to her in the sky as the constellation Boötes.

Finding Virgo in the Night Sky

If you live in the northern hemisphere, seek out Virgo close to the horizon between 9 p.m. and 10 p.m. in March and April. If you live in the southern hemisphere, look for it close to the eastern horizon at around 11 p.m. in early October
