University scientists solve windy problem.
The law of physics says solar wind turbulence should not be affected by the speed and direction of that wind.
However when the first such data from the space probe Mariner 5 was analysed in 1971, its readings were different.
Now the university's Centre for Fusion, Space and Astrophysics believe the anomaly was because the probe took a single path through the wind.
Spokesman Peter Dunn said: "What was once a small aberration was threatening to become a major stumbling block to us getting a deeper understanding of what is going on in the solar wind."
