NASA said on Thursday that its Voyager spacecraft has helped to show that the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles.
WASHINGTON, June 9, 2011 /PRNewswire-USNewswire/ -- Observations from NASA's Voyager spacecraft, humanity's farthest deep space sentinels, suggest the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles.

In a paper to be published in the April 10, 2011, issue of The Astrophysical Journal, scientists on NASA's Interstellar Boundary Explorer (IBEX) mission, including lead author Nathan Schwadron and others from the University of New Hampshire, isolate and resolve the mysterious "ribbon" of energy and particles the spacecraft discovered in the heliosphere â€“ the huge bubble that surrounds our solar system and protects us from galactic cosmic rays.
NASA's Voyager spacecraft are hurtling towards the edge of our solar system, more than 10 billion miles away from our sun. Interstellar space - the medium between stars - is a region no human-made craft has ever been.
Close to the globe, Earth's magnetic field wraps around the planet like a gigantic spherical web, curving in to touch Earth at the poles.
PASADENA, Calif., Dec. 13, 2010 /PRNewswire-USNewswire/ -- The 33-year odyssey of NASA's Voyager 1 spacecraft has reached a distant point at the edge of our solar system where there is no outward motion of solar wind.

PALO ALTO, Calif., Dec.
A University of Delaware researcher is helping to design instruments for a robotic space probe that will go where no other has gone before: the sun.
New data from NASA's Interstellar Boundary Explorer, or IBEX, spacecraft, reveal that conditions at the edge of our solar system may be much more dynamic than previously thought.
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...
