March 21, 2002: Color of the Universe
By George Grow
This is the VOA Special English SCIENCE REPORT.
What is the color of the universe? Astronomers 1 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 eye to be a light greenish color, called turquoise 2.
Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland,
reported their finding in January. They presented research at a meeting of the American
Astronomical 3 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 to 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 4 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 5 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 ... after.
identify the color of the universe. They said it was a very pretty light green or turquoise color.
They called it “cosmic 6 spectrum 7 green.
”
Many newspapers and television stations reported their finding.
Other scientists and color engineers attempted to reproduce 8 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.
They also asked for suggestions for a name for the new color of the universe.
