Giant elliptical galaxy M60 and spiral galaxy NGC 4647 do look like an odd couple in this sharp cosmic portrait from the Hubble Space Telescope. But they are found in a region of space where galaxies tend to gather, on the eastern side of the nearby Virgo Galaxy Cluster. About 54 million light-years distant, bright M60’s simpler egg-like shape is created by its randomly swarming older stars, while NGC 4647’s young blue stars, gas and dust are organized into winding arms rotating in a flattened disk. Spiral NGC 4647 is estimated to be more distant than M60, some 63 million light-years away. Also known as Arp 116, the pair of galaxies may be on the verge of a significant gravitational encounter, though. M60 (aka NGC 4649) is about 120,000 light-years across. The smaller NGC 4647 spans around 90,000 light-years, about the size of our own Milky Way.

🌌 巨型橢圓星系 M60 同旋渦星系 NGC 4647 在哈伯太空望遠鏡的銳利影像中顯得有點奇怪，但佢哋其實位於一個星系聚集嘅區域，位於附近的處女座星系團東側。 M60距離約5400萬光年，其簡單的蛋形結構係由隨機分布的老星組成，而 NGC 4647 的年輕藍星、氣體和塵埃則組織成旋轉的平盤狀蜿蜒臂。 NGC 4647 的距離估計比 M60 更遠，約6300萬光年。又名 Arp 116，這對星系可能正處於重大的引力交互過程之中。 M60（即 NGC 4649）約有120,000光年直徑，而較小的 NGC 4647 大約有90,000光年，差不多係我哋自己銀河系的大小。
