     What is the color of the universe? Astronomers had not answered this question until two months ago.

That is when two American astronomers reported on their study of all the light in the universe. They said

that the universe would appear to the human eyes to be a light greenish color.

     Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland, reported their

finding in January. They presented the research at a meeting of the American Astronomical Society. They

said that finding the color of the universe was not part of their more serious scientific research. They did it

for fun.

      However, earlier this month, the scientists admitted making a mistake. They said their finding was

much more colorful than it should have been. They now say the light from our universe is closer to white.

It is more like a milky or creamy white color.

      Their study attempted to show what people might see if they could observe the universe from far

away.  The scientists found the average color by combining light from about two-hundred-thousand star

systems. Their information came from an observatory in New South Wales, Australia.

     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 average to identify the

color of the universe. They said it was a very pretty light 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 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.
