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.

Triangulum (The triangle)

Triangulum, AndromedaThis small northern constellation presents as well-formed triangle of three stars. It was one of the 48 constellations cataloged by 2nd century astronomer Ptolemy that remain among the 88 modern constellations. It is not bright enough to jump out at the observer, but can be seen in all but the most light-polluted skies. Look for it high overhead between Perseus, Andromeda, and Pisces in December. M33, the Triangulum Galaxy, is the brightest and most notable deep sky object in this constellation.
