The Color Of The Universe
When we look up into the night sky it seems black, but scientists have observed something different. In this Moment of Science we discuss the color of the universe.
Colors
Recently, scientists have concluded that the color of the universe is beige. That’s right, scientists from Johns Hopkins gathered detailed data measuring light from over two hundred thousand galaxies, some of which are up to several billion light years away from earth. They processed this data and broke the light down into different optical wavelengths– much like how a prism breaks white light into various colors.
The scientists used a computer program to analyze the results obtained with a modern prism. Then they replaced each wavelength with the color the human eye sees at that wavelength to construct what they called a “cosmic spectrum” to represent all that energy. Finally, they varied the intensity of each color on the spectrum in proportion to that wavelength’s intensity in the universe.
So, It’s Beige?

And after all that, they concluded that the average wavelength is most similar to a nondescript beige. However, researchers initially did think the color of the universe was closer to a turquoise, but then it turned out that the computer program they were using calculated the colors incorrectly.
宇宙的顏色
當(dāng)我們仰望夜空的時(shí)候，它看上去似乎是漆黑一片，但是科學(xué)家們卻觀測(cè)到了一些不同之處。本期的科學(xué)一刻，我們來(lái)探討一下宇宙的顏色。
顏色
最近，科學(xué)家們推斷宇宙是米黃色的。沒(méi)錯(cuò)，來(lái)自約翰·霍普斯金的科學(xué)家們搜集詳細(xì)數(shù)據(jù)測(cè)量了從20多萬(wàn)個(gè)星系發(fā)出的光線，這其中有些星系遠(yuǎn)離地球達(dá)數(shù)十億光年。他們對(duì)這些數(shù)據(jù)進(jìn)行處理，并將這些光分解成不同的波長(zhǎng)，就像棱鏡將白光分解成其他各種顏色的光一樣。
科學(xué)家們用電腦程序來(lái)分析這些通過(guò)這個(gè)現(xiàn)代棱鏡得到的結(jié)果。然后，他們?cè)诿總€(gè)波長(zhǎng)里用人類(lèi)肉眼能看到的顏色來(lái)代替這個(gè)波長(zhǎng)，從而構(gòu)成了一個(gè)他們所謂的“宇宙光普”，并用它來(lái)代表所有的能量。最后，他們改變宇宙光譜中每種顏色的強(qiáng)度，使之與宇宙中的波長(zhǎng)的強(qiáng)度成比例。
所以，宇宙是米黃色的？
在此之后，他們推斷出平均波長(zhǎng)最接近普通米黃色光的波長(zhǎng)。然而，研究人員最初認(rèn)為宇宙更接近藍(lán)綠色，但隨后的事實(shí)證明，他們用電腦程序計(jì)算出來(lái)的宇宙顏色并非藍(lán)綠色。
