壮丽的螺旋星系NGC 4565从地球上看。明亮的NGC 4565也因其狭窄的轮廓而被称为针状星系，是许多望远镜在北方天空中游览的一站，它位于昏暗但整洁的后发座。这张清晰的彩色图像显示了星系四四方方、凸起的中央核心，这是通过模糊的尘埃带切割出来的，这些尘埃带环绕着NGC 4565的薄星系平面。NGC 4565本身距离我们约4000万光年，跨度约10万光年。天文爱好者很容易用小型望远镜发现NGC 4565，认为它是梅西耶错过的一颗杰出的天体杰作。

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 itself lies about 40 million light-years distant and spans some 100,000 light-years. Easily spotted with small telescopes, sky enthusiasts consider NGC 4565 to be a prominent celestial masterpiece Messier missed.
