Aries (The ram)

Constellation AriesAries is the zodiacal constellation named after the ram.  In ancient times, this constellation represented the golden fleece that was stolen by Jason and the Argonauts. It is one of the 48 constellations cataloged by 2nd century astronomer Ptolemy that remain among the 88 modern constellations. It is located on the ecliptic between Pisces and Taurus, and just south of Triangulum. It is highest in the sky at darkness and can be best seen in December.  Its brightest star is Hamal (Alpha Arietis), and most of this constellation’s stars can be picked out in most light polluted urban skies, but the constellation bears little resemblance to a ram.

Cetus (A sea monster in Greek mythology)

CetusCetus, the Greek mythological sea monster, is a large southern constellation on the celestial equator, and one of the 48 constellations cataloged by 2nd century astronomer Ptolemy. It is accompanied by other water constellations – Pisces, Aquarius and Eridanus. Its head is nestled among three zodiacal constellations: Taurus, Aries and Pisces. Its body is south (below) Pisces, and is flanked by Aquarius and Eridanus. Cetus’ close proximity to the ecliptic means that the Moon, planets and asteroids occasionally pass through this constellation. Cetus is placed highest in the sky at nightfall in December.

Cetus is home to one Messier object, M77, a striking face-on spiral galaxy. Among Cetus’ stars is an unusual variable star, the disappearing  one, or Mira (Omicron Ceti). This star’s high variability from 3rd magnitude to 10th magnitude means that it disappears from view when it dips below 5th or 6th magnitude. Cetus’ brightest star Menkar (Alpha Ceti) marks the sea monster’s nose.

Taurus (The bull)

Constellation TaurusTaurus, one of the zodiacal constellations, is most easily identified by it’s distinct and bright V-shaped asterism that represents the face of the bull. Taurus was one of the 48 constellations cataloged by the 2nd century astronomer Ptolemy that remains among the 88 modern constellations. This constellation reaches its highest nightfall ascension in February, and is found by tracing Orion’s belt stars to the right  to Aldebaran (Alpha Tauri), the bright reddish star nearby. The outlying stars in this constellation can be difficult to locate in light polluted skies.

With the exception of the brightest star, Aldebaran, the V-shaped asterism previously mentioned are stars withing the Hyades open star cluster, which is the closest open star cluster to us here on Earth. Many more stars in this cluster can be detected with binoculars or a small telescope. Also in Taurus is the brightest an most distinct open star cluster that we can see from Earth, The Pleiades (M45, or The Seven Sisters), which is located northwest of the V-shaped astersm toward and near Perseus. This open star cluster, sometimes mistakenly thought to be the Little Dipper, becomes even more beautiful with even the slightest magnification. The only other Messier object is M1, the Crab Nebula, which was created by a supernova explosion that was bright enough to be seen in the daytime sky in July of 1054.
