Nearly a year ago - on October 19, 2008 - the Interstellar Boundary Explorer (IBEX) - a NASA Small Explorer Mission - was launched into Earth orbit to discover the global interaction between the solar wind and the interstellar medium - the gas, dust and radiation environment between the stars - by measuring the neutral atoms created by that interaction.

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...
