Aquarius



Abbreviation: Aqr
Genitive: Aquarii
Right Ascension: 22.71 hours
Declination: -10.19 degrees
  Aquarius is visible in the fall in the Northern Hemisphere and spring in the Southern Hemisphere.

Aquarius (the Water Bearer) is one the oldest known constellations and has not changed much in appearance. It is one of the astrological constellations. Not very much is known about the mythology of Aquarius other than he ruled over much of the sky known as the 'Sea' in ancient Babylon. The 'Sea' included the constellations of Capricorn the 'Goat- Fish', Eridanus, Hydra and Cetus. It is not by accident that the Sun passes through Aquarius during the rainy season. Aquarius was the forebear of floods and the spring rains.

Deep Sky Objects

(PAS Catalog)

M-2

 M-2 A fine globular cluster, this object is about 10' in diameter and is relatively bright. It is sharply concentrated to the center, and is well resolved across its face. A fine object in an almost void region of the sky.

M-72

 M-72 Another globular cluster, this object is smaller than M-2, being about 6-8' in diameter. It is moderately bright, and is well concentrated to the center, showing resolution around the edges and a granulated core.

M-73

 M-73 With the possible exception of M-40 (a bland double star), this is probably the most disappointing Messier object. It is merely a 'Y' shaped asterism of 4 stars. They are probably not even gravitationally bound to each other.
