This constellation can be seen almost overhead on autumn evenings. The second magnitude star α (Alpha) forms part of the great quadrilateral of Pegasus, and from there, a series of stars form a V-shape lying on its side toward the northeast, representing Princess Andromeda, who was sacrificed to the sea monster (Cetus) as a victim of her mother Cassiopeia's vanity, and was chained together. Around Andromeda's waist, tracing the lines from β (Beta) to μ (Mu) and ν (Nu), you can see the Andromeda Galaxy (M31) faintly with the naked eye near ν, and with binoculars you can see it even from a city with a slightly brighter night sky. In addition, the star γ (Gamma) at the tip of the toe is a beautiful double star consisting of a pair of orange second magnitude and blue fifth magnitude stars, which can be enjoyed with a small telescope.

秋の宵、ほとんど頭上に見える星座。2等星のα(アルファ)は、ペガスス座の大四辺形の一部をなし、これから北東に向かってV字形を横に寝せたような形に星が連なり、母親カッシオペイア(カシオペヤ座)の虚栄心の犠牲となって、海の怪獣(くじら座)のいけにえに捧(ささ)げられたアンドロメダ姫の鎖でつながれた姿を表している。このアンドロメダ姫の腰のあたり、β(ベータ)から北へμ(ミュー)、ν(ニュー)とたどって、ν星のそばにアンドロメダ座大銀河M31が肉眼でもぼんやり見え、双眼鏡を用いれば夜空の多少明るい街中からでも見える。このほか、つまさきのγ(ガンマ)星は、オレンジ色の2等星と青色の5等星の1対からなる美しい二重星で、小望遠鏡で楽しめる。 [藤井 旭] 『藤井旭著『チロの星空カレンダー10 アンドロメダ姫物語――秋・10月の星』(1993・ポプラ社)』▽『藤井旭著『秋の星座と星ものがたり――秋の星座と神話を楽しもう』(1993・誠文堂新光社)』▽『藤井旭著『星座大全――秋の星座』(2003・作品社)』 [参照項目] | | | | | | |©藤井 旭"> アンドロメダ座 オレンジ色の2等星と青色の5等星からなる二重星。アルマクとよばれる©国立天文台"> アンドロメダ座γ星 アンドロメダ座にある典型的な渦状銀河。NGC224(M31)。同種の銀河としては銀河系からもっとも近距離にある。紫外線宇宙望遠鏡により撮影©NASA/JPL-Caltech"> アンドロメダ銀河 出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
