What is the color of the universe? Two American astronomers reported their study of all the light in the universe. They said that the universe would appear to the human eye to be a light greenish color.
Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland, reported their recent finding. They presented research at a meeting of the American Astronomical Society. Their study attempted to show what people might see if they could observe the universe from far away.
The scientists gave a number value to the colors of the different star systems. Then they added the numbers together and found the average measurement. The scientists used this arrange to identify the color of the universe. They said it was a very pretty light green color. They called it "cosmic spectrum green." Many newspapers and television stations reported their finding. Other scientists and color engineers attempted to reproduce the result.
Mark Fairchild of the Rochester Institute of Technology in New York was the first person to identify a mistake. He discovered a mistake in the computer software program used by the Johns Hopkins scientists. When the mistake was corrected, the results changed. The new color of the universe is much less colorful. It is very close to white.
The scientists have apologized for the mistake. They are now working with the Rochester Institute of Technology to produce more images of the color of the universe.
What did the two astronomers from Johns Hopkins University report?

选项 A、They reported their research on American astronomy.
B、They reported their finding on the color of the universe.
C、They reported their experiment on various star systems.
D、They reported their invention of a color identification software.

答案B

解析 本题问“约翰霍普金斯大学的两位天文学家报告了什么?”短文一开始就提到,Two American astronomers reported their study of all the light in the universe.They said that the universe would appear to the human eye to be a light greenish color. (两位美国天文学家报告了他们关于宇宙中所有光亮的研究,他们说就人眼看来,宇宙呈现淡绿色。)接着又谈到,Their study attempted to show what people might see if they could observe the universe from far away. (他们的研究试图揭示,从远处观察宇宙,人们可以看到怎样的情形。)据此可以确定[B]“他们报告了自己关于宇宙颜色的发现”正确。
