Summary:
An international team of scientists from NASA, the University of Florida at Gainesville, and the Max Planck Institute for Nuclear Physics in Heidelberg, Germany, observed the deflection of galactic dust grains by solar radiation. The discovery of the phenomenon was made possible by measurements of the ESA/NASA spacecraft "Ulysses".

An international team of scientists from NASA, the University of Florida at Gainesville, and the Max Planck Institute for Nuclear Physics in Heidelberg, Germany, observed the deflection of galactic dust grains by solar radiation (Science 17 December 1999). Galactic dust grains are very small, about four tenth of a micron in diameter. Due to their small mass, their motion towards the sun is decelerated when the particle is hit by a solar photon.
