Twenty-six percent of U.S. respondents do not realize Earth revolves around the sun, a survey by the National Science Foundation indicated.

The NSF conducts the poll on some basic science facts every two years, The Atlantic reported. The foundation said there has been little change in the percentages of correct answers since 1992.

Generally, U.S. residents showed a knowledge of science comparable to those of other countries with high levels of education, including Japan, the European Union and South Korea, the NSF said. In fact, they did better than EU residents on the question about whether Earth moves around the sun.

The most recent survey of more than 2,200 people was conducted in 2012 and just released.

On two controversial questions, whether the universe began with a large explosion and whether humans are descended from other species, fewer than half in the United States said those are true.

The Atlantic said those percentages go up by a significant amount when the questions are rephrased to ask if the big-bang theory and evolution are scientifically accepted.

No other polling data or methodology details were reported.
