Latest Heliosphere Stories
Man has officially embarked on a new adventure that surpasses Lewis and Clark's excursion across the US, as NASA's Voyager 1 spacecraft officially reaches interstellar space.
Data obtained through NASA's Interstellar Boundary Explorer (IBEX) project has revealed that neutral interstellar atoms are flowing into the solar system from a different direction than previously observed.
Thirty-six years ago NASA launched one of the longest missions in the space agency's history, the Voyager 2.
According to a new analysis from scientists at the University of Maryland, Voyager 1 has finally left the solar system – marking the first time a manmade object has entered the Milky Way outside of the Sun’s influence.
NASA's Interstellar Boundary Explorer (IBEX) spacecraft has unveiled an unexpected structure in the first complete pictures of the solar system's heliotail.
Scientists are split on exactly where NASA's Voyager 1 spacecraft is sitting within the Solar System, but new research from the space agency suggests it is on the last frontier out.
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...
