IBEX Has Helped Scientists Determine the Shape of the Heliosphere (IMAGE)
Caption
As the Sun wades through the interstellar medium, it generates a hot, dense wave like the wave at the front of a boat coursing through the sea. In this illustration, this is the boundary in darker blue. IBEX has helped scientists determine the shape of the heliosphere, which has a comet-like tail.
