Abstract

It's hard to know ourselves and our role as humanity, without knowing our precise location first. In the universe where we find ourselves (what we know not much about), there are billions of galaxies. A galaxy is a large cluster of stars (suns), i.e., solar systems; on average an ordinary galaxy contains about two billion stars (suns), which may or may not have planets around them. A constellation is a group of galaxies that depend on each other. Virgo is a very famous zodiacal constellation. Her name comes from Latin, the virgin and her symbol is ?. The constellation of the Virgin is located between the Lion to the west and the Libra to the east, being the second constellation in the sky (after Hydra) in size. The constellation of the Virgin can easily be observed in the sky of the earth due to its sparkling star named Spica. So our universe contains about two billion galaxies and many constellations; a constellation comprises several galaxies and a galaxy has about 2 billion stars. Nowadays, thanks to modern telescopes, we know a great many galaxies, but only 88 constellations have been identified by humanity (for now).
