Earliest and most distant galaxy ever observed 迄今為止觀測到的最早、最遙遠(yuǎn)的星系

詹姆斯·韋伯太空望遠(yuǎn)鏡打破了自己的記錄:人們用它觀測到了已知最遙遠(yuǎn)的星系。這個(gè)星系被稱為 JADES-GS-z14-0,科學(xué)家們觀測到了它僅處于 “大爆炸” 之后 2.9 億年時(shí)的形態(tài)。

It's just a faint red smudge, but the detectors on the James Webb Telescope are in no doubt that this galaxy, a large collection of stars, is at a prodigious distance.

該星系看上去只是一團(tuán)不清晰的紅色印跡,但是詹姆斯·韋伯望遠(yuǎn)鏡上的探測器確信該星系由一大群恒星組成,距離我們異常遙遠(yuǎn)。 

Astronomers say the observatory is seeing the object when the Universe was less than 300 million years old. Put another way, if the cosmos is 13.8 billion years old, James Webb is seeing the galaxy when the Universe was only 2% of its current age.

天文學(xué)家們表示,現(xiàn)在通過天文觀測臺(tái)觀測到的這個(gè)天體的形態(tài)不會(huì)晚于宇宙誕生后 3 億年。換句話說,如果宇宙的年齡是 138 億歲,詹姆斯·韋伯望遠(yuǎn)鏡看到的是宇宙只有當(dāng)前年齡的 2% 時(shí)該星系的模樣。

The most interesting aspect of the discovery is not the great distance, however, it's the galaxy's large size and brightness.

但這次發(fā)現(xiàn)中最引人注目的部分并不是該星系離我們超乎尋常的距離,而是它的巨大體積跟亮度。

Researchers are struggling to explain the presence of so mature an object, so early in the nascent universe.

研究者們?nèi)噪y以解釋為何如此成熟的天體會(huì)在新生宇宙的早期階段存在。

When space agencies spent 10 billion dollars developing James Webb, they promised it would do remarkable things. Two years into operations, that enormous investment is starting to pay back.

當(dāng)航天機(jī)構(gòu)花費(fèi)掉 100 億美元開發(fā)詹姆斯·韋伯望遠(yuǎn)鏡時(shí),他們承諾它會(huì)有非凡的表現(xiàn)。望遠(yuǎn)鏡投入使用兩年以后,這項(xiàng)巨額投資開始獲得回報(bào)。

閱讀理解:請?jiān)谧x完上文后,回答下列問題

1. What does the galaxy detected look like?

2. True or False? The most interesting part of the discovery is how far away the galaxy is.

3. How old was the Universe as we're observing the galaxy through the telescope?

4. How much did space agencies spend developing James Webb?

答案

1. What does the galaxy detected look like?

The galaxy looks like a faint red smudge. 

2. True or False? The most interesting part of the discovery is how far away the galaxy is.

False. The most interesting aspect of the discovery is not the great distance, however, it's the galaxy's large size and brightness.

3. How old was the Universe as we're observing the galaxy through the telescope?

James Webb is seeing the galaxy when the Universe was less than 300 million years old, which makes it 2% of its current age, if the cosmos is 13.8 billion years old.

4. How much did space agencies spend developing James Webb? 

Space agencies spent ten billion dollars developing James Webb.
