The boundary layer around the heliosphere is known as the heliosheath, and within that sits the heliopause, the very edge of this boundary layer. One of the functions of the IBEX satellite is to ...

Just in time for Halloween, scientists have discovered something spooky and strange occurring at the edge of the solar system: The heliopause — the boundary between the heliosphere (the bubble ...

In doing so, the probe crossed a boundary area called the "heliopause." In that area, the edge of our solar system's bubble, solar winds meet a flow of interstellar wind and fold back on themselves.

It had been thought that the NASA probe was already passing through the outermost section of the solar system on its way toward the heliopause — the boundary where the solar wind ends and ...

It's at the heliopause where the solar wind stops and gives way to interstellar space, approximately 11 billion miles (18 billion km) from the sun. Only two active spacecraft have ever crossed the ...

The heliopause is the outer edge of the sun's magnetic influence, known as the heliosphere. At this point, the stream of charged particles emitted by the sun, known as the solar wind, becomes too ...

One is a boundary region called the heliopause. That’s the frontier where the solar wind (the soup of charged particles continually thrown off by the sun) is too weak to hold off the ...

That doesn't mean it left the solar system, though. Rather, Voyager 1 broke through the heliopause: the area where a "wind" of the sun's high-speed plasma particles grinds to a relative halt.

According to theory, the boundary of the Solar System is marked by a region known as the heliopause, where the solar wind—particles streaming from the Sun—meets the plasma of interstellar space.

Voyager 1 hit this milestone in 2012. NASA said Voyager 2 crossed over the heliopause, the boundary between the heliosphere and interstellar space, on November 5th and the probe is now more than ...

The boundary where the hot solar winds of the heliosphere end and give way to the cold interstellar medium is known as the heliopause, and it’s also the border of interstellar space. On November ...
