Mythical Phoenix is very low and dim southern constellation that is challenging to locate from northern latitudes. Find it by drawing a line southward from Pisces through Cetus and Sculptor. Because it is located so far south, it is only visible at its highest nightfall ascension in December, and perhaps its brightest star, Ankaa (Alpha Phoenicis) will be the only star visible through the haze on the horizon. Two recently-discovered galaxy clusters, Phoenix and El Gordo, are among the largest objects in the visible universe. http://en.wikipedia.org/wiki/Phoenix_(constellation)
Virgo, the virgin, is one of the zodiacal constellations, is one of the 48 constellations cataloged by 2nd century astronomer Ptolemy, and is the 2nd largest constellation in the sky. It can be found at is highest point in the sky at nightfall in March. Virgo is located on the ecliptic, flanked by Leo and Libra. It can also be found by following the arc of the Big Dipper’s handle through Arcturus in Bootes to Spica (Alpha Virginis), Virgo’s brightest star. Some of Virgo’s remaining stars can be difficult to see in light-polluted urban skies because this is not a particularly bright constellation. Within Virgo is one of the two points where the ecliptic intersects the celestial equator. The moment of the Sun’s southward crossing of the celestial equator as it moves along the ecliptic is the Autumnal Equinox, which marks the first day of Fall.
The Virgo Cluster is a very large scale object spanning about eight degrees and containing 1,300 or more individual galaxies. The cluster is centered in Virgo, and extends northward into Coma Berenices. The member galaxies that were cataloged by Charles Messier are M49, M58, M59, M60, M61, M84, M86, M87, M89, and M90. Many other galaxies in this cluster have NGC designations. The Sombrero Galaxy, M104, is a very unusual galaxy in Virgo that is not a member of the Virgo Cluster. http://en.wikipedia.org/wiki/Virgo_(constellation)
