11 spacecraft show interstellar wind changed direction over 40 years

Like the wind adjusting course in the middle of a storm, scientists have discovered that the particles streaming into the solar system from interstellar space have most likely changed direction over the last 40 years. Such information can help us map out our place within the galaxy surrounding us, and help us understand our place in space. The results, based on data spanning four decades from 11 different spacecraft, were published in Science on Sept. 5, 2013.
