Ulysses is investigating what lies between us and the stars21 May 1999 In addition to its well-known role as explorer of the region of space above the poles of our star the Sun, ESA's Ulysses spacecraft has provided scientists with a glimpse of conditions in the distant reaches of space beyond the boundary of the heliosphere. Instruments on board the out-of-ecliptic pathfinder are making unique measurements of dust particles and gas from the cloud of interstellar material surrounding the heliosphere, allowing scientists to learn more about the history of our solar system. These and other results from the Ulysses mission, now in its ninth year of highly successful operations, are featured in an article by the ESA project scientist, Richard Marsden, in the June issue of the popular astronomy magazine, Astronomy Now.
