在遙遠的星空中,有一個美麗的螺旋星系叫做NGC 4565,人們也叫它「針星系」,因為它的樣子很細長,就像一根針一樣。它距離地球大約4,000萬光年,大小和我們的銀河系差不多,有十萬光年那麼長!這個星系在星空中的一部分名叫喜馬拉雅,是一個很適合用小望遠鏡觀賞的地方。NGC 4565的中間有一個圓圓的明亮核心,還有一些遮擋的塵埃,像是飄浮在宇宙中的小路。星迷們非常喜歡這個星系,因為它是非常美麗的天文奇觀,也是梅西耶(Messier)沒有發現的星體之一!

Magnificent spiral galaxy NGC 4565 is viewed edge-on from planet Earth. Also known as the Needle Galaxy for its narrow profile, bright NGC 4565 is a stop on many telescopic tours of the northern sky, in the faint but well-groomed constellation Coma Berenices. This sharp, colorful image reveals the galaxy’s boxy, bulging central core cut by obscuring dust lanes that lace NGC 4565’s thin galactic plane. NGC 4565 lies around 40 million light-years distant while the spiral galaxy itself spans some 100,000 light-years. That’s about the size of our own Milky Way. Easily spotted with small telescopes, deep sky enthusiasts consider NGC 4565 to be a prominent celestial masterpiece Messier missed.
