天文學(xué)家捕捉到了迄今為止最詳細(xì)清晰的一些深空星系圖像，其清晰度要遠(yuǎn)高于普通圖像，這些超清圖像以前所未有的細(xì)節(jié)揭示了星系內(nèi)部的運(yùn)作情況。

The images have been created from the radio waves emitted from the galaxies.

這些圖像是根據(jù)從星系發(fā)出的無(wú)線(xiàn)電波生成的。

What's new is that the team has dramatically improved the resolution of the radio images by linking together more than 70,000 small antennae spread across nine European countries.

與以往不同的是，這支團(tuán)隊(duì)將分布在九個(gè)歐洲國(guó)家的七萬(wàn)多個(gè)小型天線(xiàn)連接在一起，從而大大提高了無(wú)線(xiàn)電圖像的清晰度。

One image shows a galaxy sitting in the middle of jets of material, shooting out from either side – each one much larger than the galaxy itself. The jets are caused by a supermassive black hole at its heart.

其中一張圖像顯示了一個(gè)星系處于一股股從兩頭噴出的物質(zhì)中間，每股射流都大于該星系本身。這些射流是由其中心的超大黑洞產(chǎn)生的。

Another picture is of a galaxy from when the Universe was relatively young – just 2.6 billion years old.

另一張圖片展現(xiàn)了宇宙相對(duì)年輕時(shí)一個(gè)星系的樣子，宇宙當(dāng)時(shí)只有26億年的歷史。
