Earliest and most distant galaxy ever observed 迄今為止觀測到的最早、最遙遠的星系
詹姆斯·韋伯太空望遠鏡打破了自己的記錄:人們用它觀測到了已知最遙遠的星系。這個星系被稱為 JADES-GS-z14-0,科學家們觀測到了它僅處于 “大爆炸” 之后 2.9 億年時的形態。
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不清晰的紅色印跡,但是詹姆斯·韋伯望遠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。
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.
天文學家們表示,現在通過天文觀測臺觀測到的這個天體的形態不會晚于宇宙誕生后 3 億年。換句話說,如果宇宙的年齡是 138 億歲,詹姆斯·韋伯望遠鏡看到的是宇宙只有當前年齡的 2% 時該星系的模樣。
The most interesting aspect of the discovery is not the great distance, however, it's the galaxy's large size and brightness.
但這次發現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.
研究者們仍難以解釋為何如此成熟的天體會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.
當航天機構花費掉 100 億美元開發詹姆斯·韋伯望遠鏡時,他們承諾它會有非凡的表現。望遠鏡投入使用兩年以后,這項巨額投資開始獲得回報。

閱讀理解:請在讀完上文后,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.
