Explanation: 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.

说明: 壮丽的螺旋星系NGC 4565是从地球望向其侧面视角。明亮的NGC 4565因其狭窄的轮廓而被称为针状星系。NGC 4565是许多北天望远镜巡礼的必经之地，位于微弱但整齐的后发座中。这张清晰而色彩丰富的影像显示了星系的箱状隆起的核心，并被遮蔽的尘埃带所切割，这些尘埃带纵横交错于NGC 4565的薄星系平面。NGC 4565距离地球约4000万光年，而这个螺旋星系本身的直径约为10万光年，这大约是我们银河系的大小。使用小型望远镜即可轻易观察到NGC 4565，深空爱好者认为它是一个梅西耶错过的天体杰作。
