Galaxies seen in ultra-high definition 天文學家捕捉到宇宙星系超高畫質圖像

222

天文學家捕捉到了迄今為止最詳細清晰的一些深空星系圖像,其清晰度要遠高於普通圖像,這些超清圖像以前所未有的細節揭示了星系內部的運作情況。

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

這些圖像是根據從星系發出的無線電波生成的。

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,這支團隊將分佈在九個歐洲國家的七萬多個小型天線連接在一起,從而大大提高了無線電圖像的清晰度。

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星系處於一股股從兩頭噴出的物質中間,每股射流都大於該星系本身。這些射流是由其中心的超大黑洞產生的。

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

另一張圖片展現了宇宙相對年輕時一個星系的樣子,宇宙當時只有26億年的歷史。
