Blue planets?Space is not black,but light green,a team of astronomers announced on January 10． They studied the light sent out by 200,000 galaxies． What they found was that the average colour of the universe is a bit greener than turquoise．
The discovery was part of an attempt to test theories about how stars and galaxies form．Most astronomers believe that the universe probably started with a “blue period” when young blue stars filled space．Now the universe is in a “green period”．They believe it will finally enter a “red period” when the older,redder stars appear．
“The reason for the colour changing is that the rate of stars forming is changing,said Ivan Baldry,an astronomer who worked to find the average colour of light in the universe．
Research presented by NASA scientists shows that the highest point of star-forming may have occurred earlier than previously believed．It was probably very soon after the “Big Bang” that many scientists believe gave birth to the universe．
There is no way any human could actually see the green colour．
“The only way to see it is if you saw all the universe from the same distance away and it was not moving,Baldry said．Baldry and his co-worker,Karl Glaze- brook,have both joked about possible marketing opportunities for the new colour．
Perhaps colour-of-the-universe T-shirts or coffee cups could become popular．But Baldry allowed,“I don't know if you can patent a colour,that's not our business．We haven't actually been to a paint shop yet to see if they have a name for this．

选B,D 2题其他项错在哪?

蓝色星球?一月十日一组天文学家声称太空不是黑色的,而是淡绿色的.他们研究了200,000多个星球发出的光.他们发现太空通常的颜色是比土耳其玉稍淡的绿色.
这个发现是对星系和银河形成理论的探究.大多数天文学家认为当年轻的蓝色星球充满太空时,宇宙开始于一个“蓝色时期”.现在的宇宙进入了“绿色时期”.他们认为将来的宇宙还会进入“红色时期”,太空中会出现红色的星星.
Ivan Baldry,一个致力于研究宇宙颜色的天文学家说星球颜色的改变是因为它的组成成分的比例在改变.NASA的科学家的研究表明,星球形成的高峰时间可能早于我们以前的猜测.它可能发生在科学家们公认的产生宇宙的“大爆炸”之后不久.
但是没有办法让人类真实地看到这个绿色.Baldry说,唯一可以看到的办法就是从同一距离看整个宇宙,并且所有的星体都不移动.Baldry和他的合作者,Karl Glaze- brook,都开玩笑于新色彩的宇宙的市场开发的潜力.
也许新宇宙颜色的T恤和咖啡杯将会很流行.但是Baldry声明说,“我不知道你们是否可以申请这个颜色的专利,这不是我们管的范围.事实上我们还没去颜料店问过他们是否能给这种颜色起个名字.
1A 当他们研究宇宙的年龄时.
2A不对是因为宇宙的颜色并没有一直在变,只变了一种,从蓝到绿
B不对是因为大多数的星体变成了绿色,不是全部
C不对是因为同A,只变了一次
