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.

听力原文：W: I just read a curious fact. Did you know that people who spend less than ten minutes in a drugstore are five times more likely to make a purchase than those who spend half an hour there？
M: I saw that article, too. But think, if someone runs into a drugstore for ten minutes, it's usually to make a specific purchase.
W: And someone who spends more time they may be just looking.
M: Exactly. Haven't you ever gone into a store thinking that you'd like to buy something, and then talk yourself out of it？
W: Yes, I have, especially when I thought I would get it for less elsewhere, or I really didn't need it after all.
M: Exactly. But if you run into buying something specific and have very little time. You pick it up, pay for it immediately and then leave.
W: That's true. Maybe we should learn a lesson from that. Take your time and you'll spend less money.
M: I doubt if that would be true in all stores, though. In a department store, for instance, you may see a sweater or something you never intended to buy, and buy it be cause you have time to look around.
