ZANIAH (Eta Virginis). An old term -- before we understood that stars do move -- referred to the "fixed stars," the phrase really meant to distinguish real stars from the "wandering stars," the planets.
5 degrees northeast of eta Virginis. The name comes from "quasi-stellar object". A single quasar can emit more energy than a hundred galaxies, emitted (in the most part) in the form of infared radiation.
information about the stars and objects in this constellation and an illustration, go to Christine Kronberg's Virgo. For another illustration, see David Haworth's Virgo, where Vindemiatrix (Epsilon Virginis) is mislabelled as Zaniah (Eta Virginis).
